I have a 3 cylinder yamaha 90hp outboard (1998). One of the oil injection<br />hoses came loose during transit, and the 2nd cylinder caused the engine to<br />overheat. The result is a crankshaft with half the centre journal a bit<br />scuffed. I'm told by a mechanic that I would be crazy to use the motor again<br />without replacing the crankshaft ($1200). It amazes me that I cannot find<br />anywhere in Australia who can repair a crankshaft !<br /><br />Is it possible to get some sort of two part hardened metal sleeve that can<br />be fitted over the jounal once it has been ground down to restore it to it's<br />original size ? How deep is the "Hardening" on the crankshaft ? How else are<br />crankshafts repaired ?<br /><br />Thanks for your assistance<br /><br />Liam
