Raw water impeller

Spacelord

I pulled mine without disconnecting the hoses.  Getting to the hoses is a total pain in the butt on my engine.  It seems like you have a whole different set of challenges.

I pulled the belt.. then pulled a couple of pullies eventually getting the pump free.

Then I pulled the 6 or so bolts and pulled the front off the whole pump.

I was a little paranoid about getting it all back on while keeping the gasket in place.. but I managed.

I have the brass pump BTW.

Just remember to give a little gas when first firing your boat back up to get the pump primed and water flowing..

Looks like all points are covered here.. I thought I'd add just for the sake of it: I too lube up the interior ends of hoses when reinstalling.. but I have a hard time trusting clamps to hold the hose on the nipple when they're lubed up with anything petroleum based... (boy, somebody taking this post out of context sure would have a field day, huh?) .. it's for this reason I use dishsoap to lube it.. once it seats and cooks, that bad bear ain't going nowhere..... I reckon I need to add: neither am I a big fan of reusing hoses, though.. which is handy while using the soap trick- on the count you'll just about have to cut it off.. I promise you, though, that hose won't leak at the junction.

Got to love the rotozip!  before you cut, tape over the area to cut with blue painters tape, helps reduce any cracking.

Take your pick. Bummer, but it's up to you to cut it out.

For a one-off task the Harbor Freight version is often on sale for under $20.

NHSD, I have one of the cheapy HF versions. Love that thing for tight spots.

I wonder how the cutting project/water pump impeller change out went.

Concerning Volvo Penta Water Pumps.  4.3, 5.0, 5.7 all the same.  VP will tell you they are not re-buildable and you must buy new.  Around 400 clam.  But they are re-buildable for under 20 clam.  You just need a bearing puller.  The bearing and seal ring are available in the market.  The seal ring via VP and the bearing via a bearing shop. I have part numbers if you are ever in need.
