Part # N202M-16 I made a costly assumption when ordering a retro-fit pump for my M12. Catalina Direct does not allow returns if the part ordered is not for a Catalina. This was made clear when I ordered it and I was sure it was correct…………Doh! $375 shipped to your door (US only). I can send pics of the actual pump on request. 3FC5BC7F-2871-4EE4-BE7D-177D67CA4B5A.png

I did get the correct one finally. Appreciate the link though. I’ll hit them up for some spare impellers.

Out of curiosity and perhaps saving myself from the same mistake down the road, why was the N202M-16 wrong for your engine?

Wrong mounting flange. I needed this style which uses a couple hold down blocks on that round flags. A9C5DA69-F9DF-4D4E-9292-F6B55CB58C41.png

Also, N202-M16 has 1/2" NPT fittings vs the -M15 which has 3/8" NPT fittings. Easy to adjust between the two with new hose barb fittings. In fact, 1/2" fittings are probably easier to find in more varieties than the 3/8" ones.
