Strange white liquid from exshaust

[Larrys78]

93 Crusader FI 270s : Noticed after trolling for about an hour a whiteish liquid comming from the exshaust possibly unburned fuel exshaust smells gassy. Oil is clean and water in heat exchanger is clean. Anyone had this experiance before engine seems to run fine.

FYI Forgot to say No Smoke or Steam from exshaust just this white liquid not alot just enough to notice at slow troll and calm seas ( Kinda like there was a glob of white paint in the exshaust hose slowly disolving)

sounds like trans cooler may be leaking

Exactly what I was thinking.

If that was the problem wouldn't I expect to see water or foam in the tranny.

BTW thanks for your help

We didn't say it was the problem. We suggested that you look there first. Is the trans level high or low, or is it fine? If fine and clean then time to look at other things.
The transmission fluid passing thru the cooler is under more pressure than the water passing thru the cooler, hence it will leak one way at first. You may not see signs in the transmission fluid.

Does your engine have an oil cooler? Check the engine oil level.
