Procedure · 1. Keep the outboard tilted down at all times when moored or operating in freezing or near-freezing temperatures so the gearcase remains submerged. This prevents trapped water in the gearcase from freezing and damagin...
Spec · 2000 RPM conditions={"mode":"Shallow water operation","note":"If engine speed exceeds 2000 RPM, outboard will automatically return down to maximum trim range"}
Procedure · 1. After engine starts, check for a steady stream of water flowing out of the water pump indicator hole. 2. If no water is coming out of the water pump indicator hole, stop the engine immediately. WARNING: Operating t...
Diagnostic · Cause: Water pump failure or blockage in cooling system resulting in no coolant flow Test: Verify steady stream of water from water pump indicator hole
