The picture didn't load, but the model number for that pump indicates that it's the remote
intake pump for the 24v version of a Raritan
Atlantes toilet..a pump that was discontinued in 2002. Because your boat
has 24v electrical system
, you wouldn't be able to use a 12v pump, but I would NOT buy a pump that has be at least that old even if you could.
I see they also no longer make this model of pump, but make a new style with the pump outlets in a different orientation. Anyone know if that outlet is threaded or why it exists?
What you're calling the outlets are actually the INLET fittings--one on each side of the pump to accomodate connecting to a thru-hull on either side of it, or--using the supplied 90--in front or behind the pump. Raritan supplies a plug/cap for the unused inlet. The outlet fitting is on the top of the pump.
I STRONGLY recommend you give Raritan tech support a call before you do anything...800-352-5630 x 5. Ask for Jerry. I've already talked to him about this.
