MAINTENANCE SERVICE MANUAL NUMBER 22
Page 1B-40 90-860074--1 FEBRUARY 2002
Engine Coupler / U-joint Shaft Splines
NOTE: Refer to the appropriate Mercury MerCruiser Sterndrive Service Manual for
sterndrive unit removal and installation, if necessary.
IMPORTANT: These engines are equipped with a sealed engine coupler. The sealed
coupler and the shaft splines can be lubricated without removing the sterndrive unit.
1. Lubricate the engine coupler splines through the grease fittings on the coupler by
applying approximately 8-10 pumps of Engine Coupler Spline Grease from a typical
hand-operated grease gun. If the boat is operated at idle for prolonged periods of time,
the coupler should be lubricated on Bravo Models - every 50 hours.
