For optimal performance, use Yamalube 4M FC-W 10W-30 or 20W-40 engine oil. Always ensure the oil meets NMMA FC-W standards.
First, check the battery connections for corrosion or looseness. Ensure the battery is fully charged. If the problem persists, inspect the fuses and ignition switch for faults.
Regular maintenance includes oil changes every 50 hours, checking the fuel system for leaks, and inspecting the propeller for damage. Consult the owner's manual for a detailed schedule.
Maintain a steady speed, avoid unnecessary idling, and ensure the engine is well-tuned. Regularly clean the hull and propeller to reduce drag.
Stop the engine immediately to prevent damage. Check for obstructions in the cooling water intake. Ensure the coolant level is adequate and inspect the impeller for wear or damage.
Drain the water from the engine, add fuel stabilizer, and change the oil. Remove the battery and store it in a cool, dry place. Cover the boat to protect it from the elements.
Connect a garden hose to the flushing port. Start the engine and let it idle. Run water through the system for at least 10 minutes to remove salt and debris.
Check for a damaged or unbalanced propeller. Inspect the engine mounts for wear. Make sure the drive shaft is properly aligned.
Verify that all safety equipment is on board and in good condition, check the weather forecast, and ensure the fuel and oil levels are sufficient. Test the navigation lights and horn.
Use a mild marine soap and a soft brush to clean the hull. Rinse thoroughly with fresh water. For stubborn stains, use a marine-grade cleaner following the manufacturer's instructions.
