Have an odd problem here - got a 1989 Four Winns boat that doesn't want to start while in the water.

It starts fine while on the trailer with water connected to it, but once its in the water, she doesn't want to start...

Thoughts? I was told to check exhaust flaps in the out drive, as they can break and there may be too much back pressure. The carb was rebuilt a few years ago, but it made no difference for the starting issue.

The motor is a 3.0 4 cylinder, and it has an alpha one drive.
