Water laps against the luxurious Real Ships 77, the Aventura.
PowerSource: The vessel holds 5,400 gallons (20,435L) of fuel, and this is no ordinary fuel-filtering system. Joe: We installed an ESI fuel-filtration system to filter fuel for contaminants before it goes to the day tank. As a result, the John Deere engines get beautifully polished fuel. PowerSource: Any idea how much polished fuel these engines sip a day? Joe: We ran the boat in rough water and achieved 10 gallons per hour (37.8 L/hr) per engine. I think that’s great when you’re pushing 120 tons (109 metric tons) through the water. PowerSource: What type of marine gear are you running? Joe: Twin Disc transmissions with Quick Shift gears using a 3:1 reduction. It’s turning 42x35-inch (107x89 cm), 5blade Nibral propellers. The boat cruises 10.4 knots running 1400 rpm. It’s really vibration free. In addition to propelling the vessel, the engines also hydraulically power the bow thruster, anchor winch, and boat davit.
Deep in the hull of the Aventura, a gleaming white engine room with 7-foot-tall (2 m) ceilings houses twin PowerTech 6125AFM marine engines.
PowerSource: Of all the marine engines on the market, you chose John Deere for the Aventura. Why? Joe: It’s a good strong engine. John Deere offers more displacement for the horsepower. As a result, the engine works less. At 1400 rpm, it’s barely awake. When you run at continuous duty, the M1 is going to last a long time at 1400 rpm. PowerSource: What engine characteristics are most important to you, as a builder of high-quality yachts? Joe: Reliability. You want to put the engines in and have them run, run, and run. Dealer support is important, too. These boats will be in very remote locations, so we need to know that you can get the boat worked on when you have problems. We have a client in Thailand who requested a John Deere engine because of the local support he receives there. PowerSource: What did you like most about building the Aventura? Joe: The owner of the Aventura is someone who wants the best of the best, with top-of-the-line systems and components that make sense. When you’re a boat builder and have an opportunity to build a boat like this, it’s heaven.” Engine Model Displacement Rated Power Cylinders Aspiration Distributor
