Maybe there is a limp mode, once RPM are up alarm goes off? Its great news for me, the engine is good and we are on track for Lake Cumberland Poker Run. I will repay the engine gods by doing the top end services at the end of the season.

Please tell us he hooked up the external gauge before he pulled the engine!!

Yes they did, that would have been an expensive bilge cleaning! Picked the boat up yesterday, couldn't have turned out better.

Might want to check the drive and power steering bottles, alarm coming on plane is often low fluid.

You need to say who did the testing on your motor as they sound like a very honest marine shop. If they were dishonest they had for rebuilds and easy pickins.
