Re: 2003 YAMAHA 50HP 4STROKE CRANKSHAFT PROBLEMS
For some reason the connecting rod inserts went bad and the 4th journel on the crank was really pitted bad. So I took the crank to a marine shop and they tried to smooth it out with some type of sand paper and now the journel is smaller than the rest. The new inserts have a huge gap between them. The marine shop said my crank is bad, need a new one.. This is where I stand right now. Your help would be great.
