Dear Marine Professional,
As we are in the beginning of the new year, it is a great time to revisit our “Back to Basics” resources. This will enable dealers and technicians to reestablish a firm foundation for certain basic service procedures such as maintenance, troubleshooting, and more.
When working on any type of issue, whether it be mechanical or electrical, try to not overthink the problem. The word “problem” merely identifies the gap between the current situation and the desired outcome. Here at Yamaha, that is what the word “problem” represents. So, what are some ways that you can successfully assess a situation to identify what it will take to move into a desired outcome? Sometimes, all it takes is to take a step back and remember the basics. One way to brush up on the basics is to attend a YMU course or enroll in an e-learning course.
YMU courses are designed to train students to obtain the competencies that will help them assess and identify a “problem,” properly execute the correct service procedure, and successfully move toward the desired solution. To give students a structured back-to-basics foundation, our training department designed the Service Skills Training (SST) maintenance course, available for Outboard and WaterCraft. SST is a course on maintenance services such as oil changes, fuel filter changes, and spark plug replacements. However, it also offers more in-depth maintenance training, such as how to

successfully inspect and replace the timing belt or water pump.
It is imperative, for the success of any dealership, that dealers and technicians are equipped with the knowledge and technical training on how to correctly diagnose and perform service procedures. To that effect, YMU has created an educational pathway that targets specific areas of our products that will guide each student from a “Practiced” to “Advanced Technician,” and then to a “Master Technician.” Be sure to contact our training department or scan the QR Code below for more information on how you can register for classes today.
Additionally, our Knowledge Centers provide ample resources to ensure that you can look up any best practices to review such as past On Board magazines, Info Exchanges and Technical Bulletins, and Service Videos. To check out any or all of these sources of back-to-basic information, simply login to YMBS or YDS, locate the “Knowledge Center” tab, and use the search bar or category side bar to locate whatever you need.
Remember, Maintenance Matters®! Proper maintenance, completed at regular service intervals, helps protect the value of the customer’s investment and provides years of trouble-free fun on the water. As always, Yamaha Marine remains committed to providing top-quality, service-based resources designed with your success in mind. We hope that 2025 holds a great and prosperous season for you, and remember, we are here to help!
Sincerely,
Joe Maniscalco General Manager Yamaha Marine Service Division

TECH TIP CORNER
Back to Basics: The Importance of Flushing
This tech tip, from our Customer Relations team, is a “Back to Basics” reminder of how important it is to inform your customers to flush their outboard motor after each use. For new boaters, be sure to point out the location of the convenient built-in flushing attachment on the motor before relaying the steps below.
Flushing the Motor with the Built-In Flushing Attachment
Do not perform this procedure while the engine is running. The water pump may be damaged and severe damage from overheating can result.
1. If the boat is remaining in the water during flushing, tilt the outboard motor up until it is completely out of the water. This will allow the fresh water to flush out the water and exhaust passages in the midsection and lower unit that would otherwise remain below the water level.*
2. Disconnect the freshwater flush adapter hose from the fitting on the bottom cowl.
3. Connect the freshwater flush adapter hose to the garden hose.
4. With the engine off, turn on the water supply and let the water flush through the cooling passages for about 10 to 15 minutes.
5. Turn off the water supply and disconnect the freshwater flush adapter hose from the garden hose. Reattach the freshwater flush adapter hose to the fitting on the bottom cowl and tighten it securely.
If the freshwater flush adapter hose is not properly reconnected to the fitting on the lower cowling after flushing, cooling water can leak out of the flushing hose and the engine can overheat, causing severe damage
It is best to perform this maintenance procedure after each use. Built-up debris and deposits will stay in the motor if it’s not properly flushed out and can damage the unit as seen in the pictures below.
Remember, you can always refer your customer to the “Maintenance” section in their outboard’s owner’s manual for this procedure and more in-depth information. Additionally, you can watch our “Fresh Water Flushing–Maintenance Matters” service video by scanning the QR Code below.

NEW PRODUCTS Ringing in the New Year with
Yamaha is pleased to announce the following new products and updates that will continue to ensure that our customers have the very best boating experience in the industry.
New Engine Options for F150/200 Models
The new F150XHA and F200XHA models incorporate a feature-rich, power-assisted tiller handle. Paired with the electro-hydraulic steering system introduced in 2023, the new mechanical steering-assist tiller handle engages an electric steering sensor that triggers the outboard's integrated electro-hydraulic steering system. At or above 2000 rpm, the steering sensitivity can be set for lighter, effortless steering to reduce arm strain during long runs.
To promote comfort and convenience for captains of various physical sizes and to accommodate different boat load scenarios, the new steering-assist tiller handle can be adjusted up to 15 degrees port or starboard from center in 5-degree increments, whereas the height adjustment screw allows the tiller arm to be raised or lowered parallel to the boat deck or captain’s seat to modify according to captain seating preferences.
The tiller arm can also be folded and locked vertically 90 degrees at its mounting base, allowing upright tiller arm steering during loading, and trailering.
The standard-length tiller is included in the engine crate. However, you will need to order the appropriate "fitting kit" dependent on the desired handle length, standard, which includes just the necessary control cables and wire harness, or the 8" extension kit that also includes the tiller handle insert.
Design and Color Updates!
F50/ T50/ F60/ T60/ F70
This new year, Yamaha’s F50/ T50/ F60/ T60/ F70 models are adopting the modern and sleek design to match our more highly powered outboard motors— giving our product line a more unified feel.
Additionally, the F50/ F60/ F70 models are now available in our most desired color by hunting and fishing enthusiasts, Matte Brown. Originally available for the F25 only, you can now have more horsepower as well as the perfect camouflage to enhance your outdoor experience.
NOTE: High thrust models are excluded.
Our most popular color, Pearlescent White, is now available for our F50, F70, F90, and (L)F115 models.
NOTE: High thrust models are excluded.
Helm Master EX Updates!
On the Helm Master EX autopilot panel, you no longer have to hold down “Track Point” in order to engage the feature. Now, just a quick hold will turn on Track Point. Cruise control for low-speed travel in canals and no wake zones is now easier with a short press of the “Joystick” button. This will enable the captain to move the handle forward to select a desired speed. The selected speed will be maintained until the captain pulls back the joystick.

DIAGNOSING A 535 CODE ON A HELM MASTER EX SYSTEM
One question that our call center has been asked lately is, “How do I clear trouble code ‘535’ from my Helm Master EX system?” Whenever this trouble code pops up, the first and best method is to check and see if all of the components are connected and communicating properly on the CAN-bus.
NOTE: To refresh your knowledge on the CAN-bus, please refer to articles, “Identifying Yamaha CANbuses” (June 2023 On Board) and “Diagnostic Testing on Components and on the CAN-bus” (August 2023 On Board).
If you refer to the 2023 Helm Master EX 6X9 Digital Electronic Control Rigging Guide located in the Knowledge Center, you will be able to see a complete troubleshooting chart (beginning on page 251), with codes, symptoms, and diagnostic steps that will help you narrow down the cause of your system throwing this particular code.
However, some codes are accompanied in pairs, such as codes 535 and 223. Both of these trouble codes are telling you that there is a communication problem with the steering system.
For the purposes of this article, we will use a diagram of a dual application for a bolt-on Digital Electric Steering (DES) system.
As you can see, both motors are connected on the same network. Now, if you have code 535 popping up on the meter, use the above-mentioned rigging guide on where and how to check the supply voltage, key-on power voltage, and ground at the steering actuator harness.
If no voltage is present on the steering actuator harness, that means the harness needs to be replaced or there is a bad connection between your measurement point and the battery terminals. If the voltage is reading correctly at that testing point, test the continuity between pins as stated in the “Diagnostic Testing on Components and on the CANbus” article mentioned earlier. Refer to the photos above right for testing points.
Keep in mind that code 535 is specific to the Steering Control Unit (SCU), so you will only need to test for correct voltage output between the SCU of each engine and the continuity of each harness between them. If all of the harnesses are reading the correct voltage and continuity is reading correctly on the CAN-bus, this is a strong indicator that one of the DES components needs to be replaced. Once you have treated the source of the problem and cleared the code, in this case code 535, all other associated codes, such as 223, will clear as well.
Remember, this troubleshooting method (for a communication issue like this) is common for any component on the CAN-bus on any network. In summary, test to see if the component that is experiencing a communication issue is receiving power. Then test to see if the component has good CAN H and CAN L continuity between the device that is missing from the network and the component that is reporting the communication error.
4.2L B MODEL TRIM SENSOR DESIGN
Addressing Issues with the Upper Tilt Ram Rod’s Roll Pin
By Jesse Dayton, District Service Manager
With the introduction of the XTO™ 5.6L V8 in 2018, a design change was made to how trim sensors operate. The design is very different from earlier models as it incorporates a three-wire trim sender that is keyed to the upper tilt ram pin—now retained by a roll pin.
When the engine is trimmed up or down, the outer part of the trim sensor, which is bolted to the swivel housing, rotates. The inner part of the trim sensor keyed to the upper tilt ram pin that is fixed in place does not rotate. This sensor works similarly to a throttle position sensor, where the sensor is fed a 5 V supply on the orange wire and, when there is a change in position, this causes a change in resistance that changes the output 5 V on the pink wire. This
output 5 V is received by the engine’s electronic control module (ECM), and it changes the reading on the trim gauge. This voltage can also be read with the Yamaha Diagnostic System (YDIS).
This design has now been incorporated into new models introduced since the XTO, such as the F150/200SA DEC/DES models and F150/200C mechanical control models, the 4.3L F350SA, and SHO® mechanical control and 4.2L B model offshore DEC and DES motors (VF200/ 225/ 250B, F225/ 250/ 300CB, F250/ 300SB).
On the 4.2L B model offshore DEC and DES models and SHO mechanical control engines specifically, there have been reports that this roll pin (referred as a spring pin in PartsManager Pro™, reference #11 in the picture above) can partially or completely back out. When this happens, the upper tilt ram pin is no longer fixed in place, which can cause the pin to rotate on its own due to vibration, or the pin will move with the swivel housing. Both instances could result in incorrect trim sensor readings.
In situations where the trim reading is stuck in the up position, the engine may not have any trim up function. It may also activate the power trim and tilt protection feature which will put the engine in rpm reduction mode (see Info Exchange SP2024-002 for info on maximum rpm and trim sensor voltages where this feature will activate).
If the pin has partially or fully backed out, DO NOT REUSE THE PIN. Install a new pin (P/N: 91690-6002200) using a 6 mm roll pin punch (see picture below, acquire locally).
The upper tilt ram pin must be indexed properly to allow installation of the roll pin and for the trim
sensor to read correctly. There is a mark above the slot where a flat head screwdriver could be used to rotate the pin. This mark should be facing up as shown below.
While attending the Advanced Offshore instructorled training class, Wilmer Crawford of Legendary Marine in Panama City, FL, pointed out that the slot where a flat head screwdriver could be used to rotate the pin lines up perfectly with the hole that the roll pin gets driven into. Therefore, aligning the slot in the pin with the hole in the tilt ram is a quick and easy way to line everything up for the installation of the roll pin. Install the pin flush with the opening in the tilt ram (see pictures below).
For more information about the trim sensor, upper tilt ram pin, and roll pin, please reference the publications below. These publications are available electronically through the Knowledge Center found in the Yamaha Marine Business System (YMBS).

A NEW WARRANTY FEATURE ON YMBS
Yamaha is introducing a new warranty claim status, “Hold for Parts – Paid.” Yamaha will use this option from time to time to obtain parts on paid warranty claims when investigating trends or carrying out other market issue follow-ups. These paid-claim requests for parts to be returned to our Failure Analysis department will not affect the reimbursement you have already received for the warranty repair.
As a reminder, Yamaha warranty policies and procedures require all parts replaced to be held for 90 days from the date the claim is submitted, even after the claim is paid. Refer to Chapter 8 in the Outboard Warranty and Y.E.S. Handbook (P/N: LIT-11760-00-22), available printed or in the Knowledge Center in the “Warranty” category.
If you have submitted a warranty claim that was completed and paid within the 90-day period, you may still receive a message alert on the YMBS homepage as seen below.
Click on the alert to be taken to the “Warranty Claim / Authorization” page.
If the status is highlighted in red and set to “Hold for Parts – Paid,” then you should use the following procedure (which is the same as that for the regular “Hold for Parts” status claims):
1. Click on the highlighted status to generate a Warranty Parts Recall form (“call tag”). Carefully check to see what part(s) are being requested on the form; we may only request one or two parts, not all the parts replaced.
2. Be sure each requested part is properly identified with a Warranty Parts Tag (P/N: LIT-11790-02-00) and pack the part or parts carefully to avoid damage during shipment.
3. Fill in the weight and dimensions of the package in the indicated fields and click “PRINT” to print out the form.
NOTE: You only have one chance to print, so be sure to specify the number of copies before printing. It is recommended to make at least two copies and keep one in your warranty files for the claim.
4. Cut out the return label portion of the form and securely tape it onto the package. Put the rest of the form inside the box with the part(s).
Thank you for using this procedure when requested. It will help Yamaha achieve its goal of maintaining and improving product quality.
Remember, you can also have alerts about pending parts-return requests conveniently sent directly to your email so they won’t be missed. Simply insert your email address in the highlighted field below when filing your claim initially.

TECH TIP CORNER!
1.8L & 1.9L SHEARED FLYWHEEL SYMPTOMS
Has your customer ever brought in their watercraft with any of the following symptoms?
• It will crank but will not run.
• There is no spark or fuel injection.
• It has a hard start or backfires.
If so, Evan Dobbins, Yamaha Testing Supervisor for Yamaha Boat and WaveRunner, advises that these symptoms could imply that the flywheel key has been damaged.
Has the engine been worked on recently? A sheared flywheel key is usually the result of the flywheel rotor not being torqued correctly during reassembly. It is important to have the applicable service manual nearby whenever working on a vessel, so you have the correct torque specifications right at your fingertips. These additional steps will help ensure that your customer’s product is being serviced with the utmost care.
Also, a sheared flywheel key could result from the customer revv ing the engine while out of the water to an excessive rpm. One example of when this can occur is if your customer takes their Yamaha Boat and WaveRunner out of the water and runs the engine over 4000 rpm or for more than 15 seconds while discharging any remaining water from the cooling water passages. Remind your customer to consult their owner’s manual for proper operating procedures.
DID YOU KNOW?
HYDROLOCKING
Did you know that a bent or broken connecting rod is usually caused by the engine hydrolocking? Hydrolocking is caused by too much fluid, water, or fuel entering the cylinder. Because fluid can’t compress like an air/fuel mixture, the piston cannot reach the top of the combustion chamber on the compression cycle. Either the engine stops rotating, or the connecting rod suffers damage. This can happen if an engine is submerged or takes on water. However, a leaky carburetor or fuel injector may fill the cylinder with fuel and hydrolock the engine as well. Although the connecting rod will bend at the time the engine hydrolocks, catastrophic engine failure may happen later if the engine continues to operate with a bent connecting rod.
As you can see, the connecting rod is bent, and the piston is disintegrated. Remember, you can inspect the oil, fuel, air filter, and the inside of the intake manifold for signs of water to determine if hydrolocking was the cause of a piston failure.
Below is another example of a hydrolocked engine.
PRODUCTS RINGING IN THE NEW YEAR WITH
