Need help. My boat is no longer huffing with the engine (Universal M25 XPB) running (i.e. cooling water is not being expelled). There is a distinct sound when water is flowing through the system. That sound isn't there. It sounds like the seacock is closed (it isn't). When the water exhaust port...
I have a 1984 M-12 diesel in my Oday 28
I think that motor came w either a Sherwood or an Oberdorfer pump. Are the impellers compatible? The
Sherwood impeller is part num 287439
Impeller 302875 for Oberdorfer
Any idea where to find these and are they the same? The Sherwood impeller has...
I have an M-12 two-cylinder 10 HP Universal Diesel inboard motor in my 1984 ODay 28. I replaced the fresh water pump 4 years ago. I replace the sea water impeller every year.

Problem: Changing...

Has anyone else used the relocation kit by [SeaSpaceMarine.com] to relocate their raw-water pump?
My daughter's boat requires lifting the engine and removing the pump completely just to check the impeller. So instead of repeating this process every year, I am thinking of relocating the pump now...
