The white one appears to be an electric Whale brand water pump, either bilge, freshwater or icebox drain. The red one is a transducer, I'm gonna guess a speed transducer 'cause it appears to have a handle to aid in removal for cleaning.

Second what Capttb said and would point out that your wiring in the bilge seems to be less than up to spec.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Definitely a speed transducer. The top of the spare plug is visible. They are usually forward of the keel so that the water flow is less disturbed.

Should that pump have double hose clamps at each end, if it is below the waterline? I do not see how you would get 2 on.

I usually like to double clamp all hoses, the only way on that pump would be to use a couple SS clamps that are not so wide. It would be helpful to know where its coming from and going too, whether it is on the bilge side or fresh water side

Jackdale—

I doubt that pump is a raw water pump.... it is probably in the fresh water pressure system or for something like an icebox/refrigerator drain or shower sump, and likely not going to sink the boat even if the hoses come off.

The electrical is very sketchy on the entire boat, that is one of my biggest projects. The pump is inline with the fresh water supply and the sink, I have never used the water system but am guessing it pressurizes the sink water? You can clean the speed transducer while the boat is in the water from the top access point? Thanks for the help.

Yes you can. On newer boats there is a baffle that stifles some of the water flow. Regardless, after you unscrew and pull the transducer, put the replacement plug in and and tighten it. You will get water, but your bilge pump will handle it.
