Strange loss of powers question..

[kameika]

225HP OMC on a 1987 Sea Drive.

Running at no-wake speed (2000 rpm ) peeing nicely.

Rev to cruise speed- 3600 RPM when the engine bogs down to 2100 RPM for perhaps 10 seconds. Suddenly, back up to 3600.

Again a few moments later at WOT (5100) bogs to 2100, then back again to WOT without problem.

Strangest thing? A third time a few moments later. And never again.

Vapor Lock?

Another hint: To make it happen? I slightly raised tilt. Electric hydraulic drive. (Yes, 14.1VDC from the stator.)

Power pack problem? Dirty connections caused by this?

Simple vapor lock?

tilting the engine, may be carp in the carb bowls. the sea drive is very similar to the outboards heres some outboard elect testing. http://www.boatpartstore.com/page35.asp

Just had a thought.

Father and I were fishing -- anchored. Jerks in go-fast boats buzzed us.

Cylinders 3 and 6 may have gotten wet. It's possible. We were waked badly.

This kind of crap I described may be a wet plug/wire connection?
