I have had a Fourwinns Fling that the teenager has taken out for over 3 years. Problem is there is water pumping in the engine compartment a trickle at idle and a lot while under a load or higher RPM. We are in the process of pulling the engine out. It appears the water is coming in from below the engine where the engine sits on the jet drive case. Maybe from the coupler to powerhead drive shaft. I have the repair manual but it does not appear water even gets into this part of the engine? Anyone know if water circulates or could leak from this area?

I have attempted to find someone to work on this boat but noone will touch it. They stopped making them I think in 98 and evinrude/OMC venture went under. Parts are hard to come by. It still runs awesome when we keep the water pumped out of it. I'd feel more comfortable with getting it fixed versus getting a larger automatic bilge and turning the teen loose again as a mechanic who looked at it but wouldn't fix it suggested.

We have checked the hoses and no leaks. Without the motor pulled out we can not see any of the fittings to see if they have came loose.

Anyother ideas on where the water could be coming from?

Thanks!!

hoses, boots, the motor is basically an outboard engine, using many outboard parts.

Very common in colder climates for the adaptor to crack if not properly drained at the end of the season. Usually they can just be welded and work just fine.

Almost all engine parts are readily available through the BRP store. Just select the parts tab, then select TurboJet at the the first window. http://shop.evinrude.com/

The adapter is exactly what was cracked. Looks like it has been repaired once before, maybe not. We didn't drain the pepcock under the motor just the exhaust box. Didn't even see it:mad: When you say weld, JB weld or how do you weld cast iron, I am not familiar with welding cast iron, can it be done?

Thanks!!

The adapter should be cast aluminum. That's not a big job to weld for a welding shop. If you take the adapter to a couple of shops that have the correct equipment, you should be able to get it repaired.

Don't let an amateur try to repair that or you may need to find another one; at $1500. I'm sure that you don't want to do that.

Yup that would be bad. The price of the drive and other turbojet specific parts seems to be the indicator of a whithering parts supply. Thank god the engine is standard.
