Before the propeller shaft is connected to the reverse gear flange, check to make sure that the flanges are parallel. A

Move the flanges together so that the guide engages. Then, with the flanges pressed together, check that they are parallel and that a 0.10 mm (0.004") feeler gauge cannot be inserted anywhere inbetween them (A). Then turn the flanges 90°, 180° and 270° and repeat this check at the new positions. Make sure that the flanges are well pressed together during the entire check. If the deviation is greater than 0.10 mm (0.004"), the alignment must be re adjusted. Remove any aids being used and connect the shaft to the reverse gear flange, or flexible coupling. IMPORTANT! The alignment should be rechecked again a few days after the launch when the boat is completed (extra critical with sailboats).
