I have an '03 5.7 gxi with a duo prop outdrive and noticed that there used to be 3 sites of water flow exiting the outdrive; 1- directly underneath where the it exits the transom, 2 - from the propeller hub, and 3 - the outdrive port directly above the props. Now water only exits site 1, not 2 or 3 and it's running at 190 degrees. My question is, What would be the most likely source of this problem?

Re: impeller failure signs

Pull off the impeller housing and take a look. It's easy to get to, on the front of the engine. If you find that it's broken, make sure to track down all the piecees as they can block water passages and cause problems. They usually collect in the thermostat housing. What you find will help determine your next steps.

Re: impeller failure signs

When was the last time the impeller was replaced? Volvo recommends a yearly replacement to prevent overheats.

If you do take the old one out to "Look" at it, the vanes should straighten out within a few minutes.

Bet your impeller looks like this Junk one.

So it sounds like an impeller problem, eh? Thank you both for your fast responses. Can someone send a picture of the location of the impeller housing?
