OEM parts are readily available for these units. Built properly, these units will last for the life of the boat. The main issue with the shift dog clutch units is the shift cable maintenance. All the cables manufactured, stretched and caused shifting and adjustment issues. It is of the utmost importance, that all shift components are kept in good working order. This includes shift cables, control box, pivot arm, shift arm and pivot arm bushings.
There should be a 1” brass fitting with a grease zerk in it, on the starboard side of the gimbal housing, just in front of the drive mounting area. If this is an aluminum plug, you probably have the original bushing and shift components. These should all be checked and the brass bushing installed. Our warranty is contingent upon the shift system being in good operating condition.
