Volvo 5.7 OSxi-E Raw Water Pump Replacement

[Island Time]

I have to replace the raw water pump on my 5.7 OSxi-E Volvo. How do I get the serpentine belt off?

The boat is sitting in the water and I also need to know how to shut off the water coming into the pump while I'm replacing it. Is there a seacock somewhere?

Any advise?

To release the belt, turn the bolt head in the center of the automatic tensioner (item 11 in pic). It will only move a short distance, (don't force it) but it will be enough to slide the belt off idler #10.

If you go to the link below, you can download a free owners manual for your engine. It shows the belt tensioner and how to change the impeller.

As for shutting off the water to do the pump, there is no shutoff. Best thing to do is pull the hose off and put a plug in it. Even a rag will stop most of the water while you change the impeller. The bilge pump will keep up with the little that does come in when using a rag to plug the hose.

Since this sounds like it's your first time, I would strongly suggest you pull the boat out of the water to do the job.

I read your post and find it helpful... I leave my boat in year round (use a BoatSafe heater) - I see a repair(s) in my near future - here is what I noticed when I went to start the engines last week - (2003 Cabrio 330 - with twin 5.7... xi) my stbd raw water pump is dripping a small amount of rusty water and my port was doing the same but now dripping much more with oil mixed with the water - before I embark on replacement, any idea where the oil is coming from - scares the hell out of me!

Any info would be greatly appreciated...
