better yet contact a reputable dealer.on a motor that new my intuition says yamaha will at least pay the parts if its a defect even if its out of warrenty.
I have seen yamaha pay for stupid things 10 years out of warrentry. the key is to take it to a dealer with a good realtionship with yamaha.
you explain why you think the crank is buggard and I may shoot you some email adddress's

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.
