Maintenance Engine Overheating (All other Models) If your engine overheats, the audible alarm will sound and a temperature gauge on your instrument panel will indicate your engine is overheating. 1. Turn off the engine. 2. Tilt the drive up and look for obstructions to the water intakes (e.g., seaweed, plastic bags, etc.). 3. Lower the drive unit. 4. Start engine and run in NEUTRAL at 1500 RPM. 5. Check the engine gauge to verify the condition. 6. If overheating still occurs, do not operate the engine unless it is an emergency. Only operate it until you are clear of the emergency and seek a tow to shore. 21195 CAUTION! Continuing to operate an over- heating engine will cause engine damage.

Engine Flush Volvo Penta engines incorporate an engine flushing port designed to flush the engine with fresh water while the engine is running. If flushing the engine with the boat in the water, the engine should not be run higher than idle or sea water may be drawn in with the fresh water. 1. If the engine is running, shut it down. 2. Remove the blue plastic cap from the hose that is clamped to the starboard side of the engine. It is marked with the running engine flush symbol ( 1 ). 3. Connect a water hose from a fresh water source to the flush connector on the engine ( 2 ). 4.
Turn water on full and start the engine. 5. Let engine idle until engine temperature stabilizes at its normal operating range. This will allow the thermostat to open and ensure the fresh water circulates throughout the engine. 6. After engine is flushed, shut engine the down. 7. Disconnect water hose and reinstall the cap. CAUTION! When re-installing the blue cap on the fresh water flush hose, tighten it by hand, then tighten 1/4 turn using a wrench. If the cap is too loose, air may be sucked in, caus- ing the engine to overheat, resulting in dam- age. 22347 Drain the engine if freezing temperatures are expect- ed.
