Oberdorfer N202M15 on M25XP

Hi guys,
Thanks so much for all of the suggestions and ideas, I really appreciate all of the help you provide. Sorry it's taken me a while to follow up.

It appears that the thru hull got plugged after leaving my slip. I always verify that water is flowing after starting the engine. I ended up blowing out the inlet line and something finally broke loose. After that, I was able to get the old pump to pump water. It was still dripping, so I put on the spare pump and it worked fine. I've taken the boat out a few times and just motored around for hours. (No wind anyway) So far so good. I will either rebuild the old pump or have it rebuilt to keep as a spare.

The only real difference that I can see between the 2 pumps is the cover plate gasket. The replacement pump has an o-ring and the original pump had a paper gasket. The inlet and outlet elbows fit both pumps.

Thanks again for all of the help!!

Just FYI when you rebuild the old one, you can get a cover from Moyer Marine that upgrades the 202 to an o-ring.  It's 'specially for the old pump bolt pattern (not interchangeable with between the 202 and N202.)
