Thru-Hull Transducers

[SkunkBoat]

FYI, in a pinch one fall, when my transom mounted skimmer failed, I just propped up a new one inside the bilge in the inch of water that is always there. That got me thru the fall bass run with only an occasional problem when it toppled over.
In the spring I removed the transom mount and sealed over the holes with glass and epoxied the new skimmer to the inside off the hull on the flat area. I guess a picture would help....got it...
I just sanded the area and epoxied using the gel type resin (careful not to make bubbles mixing in hardener).

That one lasted years but the plug corroded so I bought a shoot-thru from LEI.com. That one came with a packet of adhesive. Did need to build a dam with silicone. It has a temp sensor cable to run out to the transom.

They both work great. No problems to 260ft, which is as deep as I've been.

I would never mount a skimmer type outside of the hull ever again.
