Pro 785 ADVISE? Water in engine bay over winter
Hi can anyone help me out, i didnt cover my skis this winter and water got into the enging bay! The skis was tilted back so the water drained off the foot deck, water didnt touch the engine, it collected buy the pump at the back of the skis I tryed turning them over buy hand and both skis are locked up solid!
when i turn the output shaft with a spanner and the plugs removed i can see down the plug hole that the pistons move slightly.
I dont think the engines are NOT seized but i cant understand why the pumps seem to be locked up!
Please can anyone give me so advise?
Is it easy to strip down the pumps and replace the bearings? thats all i can think it is!!!
WHAT YOU THINK?

If I'm reading this correctly, you're saying that water collected in the actual pump where the impeller is or water was inside the engine bay towards the back of the hull?

How much water was inside the hull? How deep around the engine?
The jet pump is easy to remove. Instructions have been posted elsewhere on here.
Once removed, you can assess the problem.
Jet pump is straightforward to rebuild, just need a tool to remove the impeller.

Spray some lube down the clyinders so the rings dont stick.

Your first step is to see whether it is the pump that is locked up or the pistons that are locked up. As stated above, just remove the pump then try to turn the engine over. If it still doesn't move, you know the problem is with the engine.

There is no access to the pump from inside the hull, you probably have a bad thru hull bearing.
