Default Do I remove this Ducer?

Purchased a 28 topaz and starting to think electronics. Before I get going this is an abandoned transducer that is now just 6 inched behind the stb engine intake, so not a usable location for anything.

Do I try and remove of just leave in place?

Thanks for any all help.

If it's not in your way or bothering anything, why? Do a cost benefit analysis... It will cost you several hundred at least to have it removed and repaired. While you are at it, may as well prep the entire bottom. What is that repair and bottom job going to get you other than removing that ugly thing from the bottom? If it leaks and costing you considerable GPH I would give it a serious thought.

That protruding B744V or similar T/D and doubled fairing block is creating a substantial drag at no benefit , as well as having risk of strike damage and leak. Too bad there is an intake a bit ahead ( but must be more than 6", no?) as otherwise a flush mount T/D like the B175 HW models would be a good solution to fill the hole ( made a bit larger.) (That's what I had done. Gained a little speed & economy at cruise rpm and had to use less beam-corrective trim tab and the sonar results were way better.)

If that is really not feasible, I agree with Daybreaker above.

First rule of boating, anything that is not essential to the operation of the boat should be removed.

Here is the inside pic I have absolutely no access to repair this from the inside. the old transducer is below the starboard engine and just getting the pic was difficult So I guess its staying put. thanks all for help, I should have checked for access before even considering.

I had a 28 an it had a transducer behind the port engine in a tight space next to a string. It was had to get out due to the location of the engine mount. The best method would be to use a dremel moto tool and cut through the nut. Only one cut is needed. Cut it and use a screw driver to open it up a little, then it will screw right off and you can push the ducer through the hole. Glass it up.
