Water circulating pump re-build?
 

Does anyone do it? I have one that is starting to drip out the weep hole. I took the back cover off and it seems the only part that is "marine" is the stainless back cover and bolts....would a automotive one work if I re-use the back cover?

Merc wants about $300 for a new one.

You can probably get a Siera marine brand one for 150 or less.. They make very good parts..

finding the parts to do it would be the issue I think...

I've bought 3 marine pumps for less than $100 from a advertiser here a couple yrs ago. All still going strong.

The only thing I remember buying made by Sierra were seawater pumps...I could have made pumps out of paper-mache that would have lasted longer.

That certainly looks like the right part, I'm just skeptical since it's so much cheaper than Merc's......but THANKS!!!

$89 I've bought these myself.

Maybe it's because Merc is overpriced to start with? ;)

+1 installed one 3 years ago running in mostly salt water...no problems to date

PM 45SS in the Sonic forum he redid all three of his. Or I can try to get you his number.
