For more than 30 years, Yamaha Outboards have delivered far more than superior power, performance and efficiency. Yamaha owners get something that can't be measured in HP or RPM - legendary Yamaha reliability. Maintain this reliability with genuine Yamaha outboard parts.
Two-stroke outboard motors can reasonably live between 1,500 to 2,000 hours before needing major maintenance, and 4 stroke engines can last longer. All engines will last even better with proper maintenance and preventative measures.
