Yamaha 8 HP Outboard Motor

Yamaha 8 HP outboard motor. Model 8MSCH (2004) 2 Stroke. It's tested and working. It has a head issue with pitting on the head where the exhaust is blowing over to the water jacket. This prevents the water from cooling the unit above mid rpm. (Needs work to resolve) Has new prop. New waterpump impeller. Starts great. Runs great. Except for the known gasket issue.
