Raw Water Pump Seal

[kk lowrider]

Is it possible to change just the seal on the raw water pump pulley I have water coming out of the weap hole after changing the impeller on my volvo 4.3 2000 but to be clear was leaking before I changed the impeller, but now it leaks worst.

Re: Raw Water Pump Seal

yes, that seal can be changed. finding a new seal. or more correctly, someone to sell you one, can be tricky. most places will tell you that you need to change the whole assy.

It's not as ominous as hbm states.
You can order the seal here at iboats at the link below, or go to your nearest Volvo dealer with the number.
You want item #6

I stand corrected. My experience was with a Merc. NOT a Volvo

I`m thinking he means the engine circ pump . If so you will need to replace it as a unit.

The 2000 model VP engines have an engine driven raw water pump. It does have a weep hole and they will leak there. You can replace the seal. Not sure what the condition of the bearing will be, but the seal is replaceable.

I think I found the same problem and I want to fix it myself. You can see the steady stream of water beneath the raw water pump. Is this what your leak looked like? I just can't believe a pump would wear out after 6 years of relatively minimal use each summer. Is this normal?!

I've got a 4.3VP build 2002 I'm pretty sure. The impeller's never been changed. I just noticed the leak this passed weekend after hooking it up to the hose and ear muffs after storing for the winter.

How long of a job was it for you?

Re: Raw Water Pump Seal

This was not bad at all and if you are mechanically inclined you can do this in about 1 hour tops. Just remove the impeller bracket then the impeller housing 4 small brass bolt then remove the fan belts then the 3 large allen bolts on the pulley then remove the pulley and gently remove the center seal without scraping the shaft replace the seal part #827247 the sealing ring $8 bucks at the dealer or you can order it right here. I would replace my impeller and o ring while you are there. You can do it. If you have any questions I will be happy to help KKlowrider

Re: Raw Water Pump Seal

So, the sealing ring replacement looks to have solved my leak problem. Not a drop feel into the bilge when I started it up. I'll follow this reply up with my experience- Thanks KKlowrider for your instructions; couldn't have done it without you!

Question now is, I thought I read somewhere that I should be seeing water spit out of the exhaust/ prop. When I started her up after fixing the seal, and ran her on the ear muffs with a little water running there was no water misting or anything coming out of the exhaust.

Now, I don't remember water coming out if there last year when I started it on the ear muffs either.

I double checked everything, inlet and outlet hose installation, direction of impeller (replaced with new), hoses pointing down, etc. but don't know how I could have done this backwards.

Maybe because I didn't let the engine run long enough that water did not have time enough to circulate in the engine after having been drained during installation?

Any thoughts?
