How did you know the rev limiter actually caused it?

Yea, happened yesterday. This is embarassing, but here goes. Its an SBT. I got the crank new in a package deal when I bought the donor 1200 boat. I actually sent the crank to Competitive Crankshafts and dropped $200 on it to have it inspected and rebalanced etc (and this was a new crank). I felt comfortable running it at that point. If anything would of failed, I thought it would have been a bearing. I also thought that this portion of the crank was OEM, even if it came from SBT. I dont know though. Maybe somebody knows?

most likely when you sent a "new" crank into the shop....they picked it up, looked at it..laughed and said its fine.....then billed you 200 bucks

sean it more them once on the same boat. drop the limiter back down and it stoped snapping the crank off. but that was 100 years ago. not the same motor but same thing happened. i would put this one on a combo of a sbt good for stock and not much more crank and lot of rpm. just my op.

the old school kawe guys will know what im talking about.
