Hey everyone! this might be a stupid question, but what are the 3 cylinder type things with a wire coming out of them on either side of the engine at the bottom of the boat??

The 2 on the left, the wire broke off. The one on the right still has a wire attached with some type of plug at the end. Wondering if these are important and what they do!?
 
Those look like shoot-through-hull transducers for a depth gauge/fish finder.
Must have been one stopped working and they decided to install a new one in a different place? If those are epoxied, I would leave those alone!

I dont plan on removing them but theyre not plugged in and i dont know where to plug them into anyways. They dont go all the way through the boat tho. Could they still be a depth / fish finder? Maybe something else?

Yes, it's a silly name "shoot-through" - the signal shoots through hull fiberglass, there is no opening/ cut-out.

Yep. Fish finder transducers. Previous owner took the head unit and left the transducers.
 
I’m pretty sure they’re bilge pumps. The one on the bottom left even says “bilge” on the blue label. Possibly a stock one, a backup, and ones a replacement for an old burned up one? The first hole cuts through the engine compartment floor and the unit rests on the bottom of the boat bilge.
 
Although not sure why there’s no discharge hose on them :confused:

I don't think so.

maybe the power to that one was on the bilge circuit ?

I agree with the transducers just very strange with the writing on the tape,

Do you have a bilge pump?
 
They're transducers. Maybe they wrote bilge on them to make sure they were mounted in the bilge area and not somewhere there is a double hull. No hose connections = no pump.
