I recently bought my first boat it has a 1989 forcer 150. The engine had spit #5 cylinder ring. I put a new piston and rings honed the cylinder. the engine actually ran to my suprise. when i ran the water through the engine water was coming out the exhaust also leaked a little through the exhaust manifold gasket. im thinking there might be a gasket leaking but i don't know where the water flows through an outboard engine this is my first time working on one hope to hear from someone thanks.
