I think you will find eBay to be the cheapest source. Or perhaps Amazon.


However for the price of the kit and shipping etc, I’d replace the whole pump for the extra $75.

Duane, Craig, Bill, Mark and al,


Thanks for the info, very useful !


Does anyone has a good reference/source for the major rebuild kit for that pump?

Actually, you're right - it is easy-peasy and you definitely don't need to go to the expense of a shop rebuilt. I agree with Mark that having two pumps works great - you can rebuild one at your leisure after popping the new one on. I do this with both my genset and my main engine water pumps - have rebuilt them both many times over the years.

In lieu of a press you can just carefully tap out the shaft using a socket from your socket wrench set as a "pusher". On reassembly you may want to put parts in the freezer and/or hot water to make them go together more easily. Sourcing parts is easy.

Have fun with it!

Cheers, Craig Briggs

Bill R.,


Thank for your post.  I actually had a rebuild kit on board (memory is an occasional thing for me these days it seems) and though easi-peasi, just rebuild the pump!  But it will take a shop to get this one apart.


I agree with you, another pump is the way to go.
