Valve, Pressure Control

For a number of obvious reasons, mostly to do with safety and peace of mind, your Yamaha marine engine has to be reliable (safety) smooth (comfort) and powerful (safety, comfort and overall performance).
The engine this component suits is renowned for its rugged reliability and longevity, so when the time comes for a complete refurbishment/rebuild, make sure that any part displaying wear, damage or excessive salt water corrosion is replaced with a new component if the old item is beyond economic repair?
