[QUOTE="chrispbrown27, post: 382389, member: 9661"] An uncle of mine recently bought a boat with a 1990 Johnson 9.9 on it. He ran the motor 3 times with the motor running perfectly. Fourth time out it fired right up and idled great but when he tried to throttle up it would choke out and die. He took it to a mechanic up there and he got the news today that it has a blown piston. I have never gotten that far into working on a motor but thought I would ask you guys if you think it is worth repairing or is he better off buying a different motor. The mechanic told him that the piston is no longer made and can't be found, but I found one that is supposed to fit on ebay for $35. What else would I be looking to do while I am in there? [/QUOTE]
