Yamaha Water Pump Impellers
The Yamaha outboard water pump impeller helps circulate cooling water through the engine. Impellers wear over time and should be inspected or replaced according to the maintenance schedule for your specific Yamaha outboard.
Yamaha Thermostats
Yamaha thermostats help regulate engine operating temperature. A worn or damaged thermostat can interfere with proper cooling-system performance, so select replacement thermostats based on your specific engine.
Flush Your Yamaha Outboard
Regular Yamaha outboard flushing helps remove salt, sediment, and debris from the cooling system. Yamaha recommends making flushing part of routine engine care, especially after operating in saltwater or other environments where mineral and debris buildup can occur.
Yamaha Spark Plugs, Anodes & Tune-Up Parts
Yamaha Outboard Spark Plugs
Maintain reliable starting and combustion with the correct spark plugs for your Yamaha outboard. Spark plug type, heat range, and gap vary by engine, so use the exact specifications recommended for your Yamaha model rather than choosing a plug based only on horsepower.
Yamaha Outboard Anodes
Yamaha sacrificial anodes help protect compatible underwater engine components from galvanic corrosion. Inspect anodes regularly and replace them when sufficiently deteriorated. The correct anode material may depend on whether your boat operates in saltwater, brackish water, or freshwater.
Yamaha Maintenance Kits
Save time gathering routine service parts with a compatible Yamaha outboard maintenance kit. Depending on the kit and engine, contents may include filters, spark plugs, thermostats, anodes, water pump components, seals, or other commonly replaced maintenance items.
Yamaha Marine Grease, Lubricants & Corrosion Protection
Yamalube Marine Grease
Use compatible Yamalube marine grease at specified lubrication points to help reduce friction and protect moving components exposed to water, salt, and vibration. Follow your Yamaha owner's manual to identify the appropriate lubricant and service points.
Yamaha Propeller Shaft Lubrication
Routine propeller removal gives boaters an opportunity to inspect the shaft for fishing line, damage, and corrosion. Apply the Yamaha-recommended marine grease when specified before reinstalling the propeller and related hardware.
Yamaha Corrosion Protection
Saltwater and moisture can accelerate corrosion on outboard components. Yamaha corrosion protection products, freshwater flushing, regular cleaning, lubrication, and anode inspection can all play a role in protecting an engine operated in marine environments.
Yamaha Outboard Storage & Seasonal Maintenance
Preparing a Yamaha Outboard for Storage
Extended storage can require more than simply turning off the engine. Depending on your Yamaha outboard and storage conditions, preparation may include treating the fuel, changing engine and gearcase oil, protecting internal components, maintaining the battery, flushing the cooling system, and applying corrosion protection.
