Parts Needed
Dealers will need to order parts for this Program.
Action Required
1. Using a flashlight, look through the marine transmission housing vent holes to inspect the existing coupling between the engine and transmission.
2. If the existing coupling is a rubber block drive coupling, replace it with a 1325533 Coupling.
3. Replace the 7E6040 Input Oil Seal.
4. Place a thin film of sealant (Loctite 242 or equivalent) around the outer diameter of the input oil seal and press the seal into the bore flush with the outer face of the rear housing.
5. If the transmission fails before the coupling is installed, repair the transmission and include the costs of the repair under this program.
