Moving the transducer

[dogbert]

Has anyone ever tried moving a transducer? Can it even be moved?

I'm trying to find a place to put a thru-hull connector for my ballast system for the water in-take, but the best place to put it just happens to be right in front of the transducer for my depth finder. The transducer appears to be epoxied to the hull.

If not, can I get a replacement transducer for a Hummingbird depth finder or do I need a whole new depth finder (gauge and all)?

Any suggestions are appreciated.

I know how to get it off the hull, place the end of a 2x4 firmly against the transducer horizontally and give the other end a sharp rap with a hammer, should pop it right off.

The problem is placing it back on the hull, it has to be in a position free from turbulence from fins, intakes, etc. If you can just move it forward from it's current position then that would probably be ideal.

It also has to be bubble free in the epoxy or you can have false readings. Place the epoxy on the hull in a patch a bit bigger then the transducer. Place the transducer in the epoxy at a 45 degree angle and slowly twist it into the forward position while pressing down. This not only doesn't create bubbles but helps force out any already there.

This maybe more info than you wanted but hey its better to have too much than not enought right!

So, I don't have to try and get the old epoxy off?

I was just planning on moving it to the other side of the hull from where it is now. There should be nothing obstructing it in this location.

Off what, the hull or the transducer? Leaving it on the hull won't hurt a thing, and i don't think you really need to remove it from the transducer. In fact i think it would be a bitch to try! You'd probably do more damage trying as not. As long as you put it in to avoid the bubbles the epoxy will fill any voids. Just check in front of where you want to place it and make sure it's not right behing the impeller intake or such.

Cool, that's what I needed to know! Thanks, man!

One question, what type of epoxy do I use?

Dogman - Let me know how it turns out. I wsa thinking about buying a used one a couple weeks back, but then we all decided we probably couldn't remove it without hurting it.

I have put several in bass boats, as well as the one in my Tige. I used 2 part epoxy from WalMart. I think it is made by Duro. Never had one come off.

Pretty much any epoxy that hardens to plastic will work as long as it isn't the quickset type. The quickset will have more air bubbles b/c of the quick temperature shift.
