IMPORTANT: These engines are equipped with a sealed engine coupler. The sealed coupler and the shaft splines can be

Lubricate the engine coupler splines through the grease fitting on the coupler by applying approximately 8–10 pumps of

NOTE: On Bravo equipped models, if the boat is operated at idle for prolonged periods, the coupler should be lubricated every
50 hours.
