Anyone know the brand/specs for the AC unit seawater pump that sits just outboard of the starboard motor? 2001 4600 SCB.

Thanks,
Steve

Here's info for a 1999 4100 SCA ... might help you - probably close if not the same.
Dometic Model 331566 115V 2.1 Amp Replacable with Dometic PMA1000 AC-5C-MD

It shouldn't matter, provided it's an AC (Alternating Current 110v - 120v) continuous duty circulation pump.

I believe mine is March pump.

That’s what I ended up buying. Direct replacement but in a terrible location. Getting too old to squeeze around the motors.

I'm the same way. On the 41 SCA the rear AC has a lot less water flow than the forward AC....so it clogs up a lot easier. I just had to run a new water line to the rear AC after 4 years or so. In Pensacola. Tried flushing it...gave up and ran the new hose.
