New user.. asking a “dumb” question.. pump cycling

i have lifted this hatch before and we did see the bilge so I am aware of where you are talking.. We are anxious to get down to the boat on Friday and roll up our sleeves and start problem shooting for this as well as tracking down our slight water leak in the engine bilge area.

On bilge leaks, the first order of business is to taste the water. If it's fresh, that's another indication that you've got a fresh water leak somewhere, that's causing your FW pump to cycle.

We are on a fresh water river so I don’t think tasting it is going to do me any good on this one. But I have another post on here that has given me a lot of places to start so we will try trouble shooting this weekend tracking it down. My fresh water tank has yet to go down over the last 2 weeks so we believe something might have vibrated loose on our 7 hour ride home on the River after we bought it.

That's a good observation if your tank hasn't gone down, but I have replaced 98% of my freshwater fittings because they were all starting to leak. My tank didn't go either because the drips were all small in nature but it drove me crazy.

Major sources of water in a bilge are raw water cooling for motors, dripless shaft seals, rudder posts, hot water tank, freshwater fittings and I'm sure a few options.

I too chased down water in my bilge and found one of the sources was the water pump for one of the Air Conditioners.
These are not mechanically coupled but rather magnetically coupled.
In my case, the water pump was leaking. In the example picture below, it is the white plastic part.
If this indeed is your leak, the pump can usually be sourced separately from the motor.

thank you! This is very helpful as well!
 
First thing, I confirmed the sound I was hearing all night was indeed the AC pump and it’s working properly.. just me getting used to all the sounds and what they mean .. secondly, I found the source of water in the bilge.. which is a crack in the raw water housing on the starboard motor. Once my husband gets that fixed I’ll clean up the bilge and hope that it was the only source of water.
