voltage mismatch weirdness

[xeon_tsd]

My water pump sounds like it is dying. It is old. It cycles yadda yadda rebuild or replace. It's a boat this sh1t3 happens. I go take a pic of it to find a new version etc, and I see that it is a 24 volt model!?!?! I have NO 24 volt systems on this boat. WTF!?!? I have not yet run a tester on the wires to see the voltage... that is coming up this weekend when I can really move stuff around and get down, twisted around, Stand on my head etc... BUT for now my question is... what would the 2 volt pump be running like on the 12 volt system? Would the pressure be half? OR?????

31595-0094 PAR-Max 2+
Voltage 24 (Vdc)
Amp Draw 2 (amp)
Fuse Size 7 (amp)
Cut-In 20 (psi)
1.4 (bar)
Cut-Out 40 (psi)
2.8 (bar)

It would be drawing approximately double the current and perhaps take longer to reach the cut out pressures its set to.

Very odd that someone would install a higher voltage (more expensive) pump on a 12 volt system. Might you have a converter on board that you didn't know about? Check the voltage on the circuit. If it's a 12 volt circuit, just replace with a 12 volt pump.

Yay!! A new 12Volt water pump and all is well with the world... well with that part of it anyway! Why in the heck there was a 24 volt there?!?!?!?! i will never know.

Previous owner got it at a flea market. Didn't ready the label. A pump is a pump, right?
