Had #4 cylinder to seize up on my Yahama 130 hp outboard. Only thing can figure is rings let go and metal fragments locked up motor. Really damaged cylinder wall and top of piston. Ive called few places about trying to fix motor. Some don't want to mess with yahama because of the Price of parts and others say cost more to fix than worth. Just wanted to get some opinions from other members before deciding........ Thanks fellas for any info
