Mounting a transducer

[Fisher Dude]

I am planning on mounting a transducer to the back-end of my tinny. I do not want to put wholes in the boat below the water line. Is there any substance that glues well to aluminum?

Thanks,

Drill and tap a piece of aluminum plate to accomodate the transducer bracket. There is a glue that will bond rubber to metal ( I don't remember the name of it but I will try to find what it was and post it). Take a piece of tire tube and glue it to the piece of aluminum then glue this to the boat, so the rubber is sandwiched between the hull and the aluminum plate. I know someone who did this and it has held for years. It's recommended to pry it off every few years and replace the rubber just to be safe but it works well.

wouldn't JB weld work!?

this stuff you can get a canadian tire, get the 10minute drying one.
sounds like a good idea about sandwiching it with (tire tube)..

The name of the glue was: RemTech Tip Top 2000 vulcanizing compound.

I used to use a portable fish finder with my 12 footer years back. I mounted the transducer at the end of a steel rod (actually it was one of those wall shelf brackets with all the holes in it). I drilled a hole in the gunnel on the top of transom and attached it with a bolt and wingnut whenever I needed it.
You set up the length of rod with the transducer to the right length and once drilled, it will always be at the correct depth and position in relation to the bottom of your boat. The shelf bracket I used as the rod to hold the transducer was half a hollow square, so it had an area in the back for the cable which I secured with zip ties. Worked perfect.
Another benefit is you can loosen the wingnut and move it out of the way when you pull it up on the beach, etc.
Worked perfect. It may just be the ticket for your type of fishing.

Thanks guys!

I used Marine Goop to mount everything to my boat. Works perfectly. I have mounted my transducer to my transom, fishfinder to my dash and GPS antenna to my gunnel, all without drilling one hole. When it drys, it is like cement, but if you need to remove what ever you mount, you just have to apply pressure and cut the goop away. I fyou ued contact cement it is harder to remove.

Wow...I think I have about 300 new holes in my rig...and that is just for all the RAM mounts.

Just wondering if the bonding will hold in rough conditions?

I can just imagine the damage a transducer would do to a lower unit and hull if it came off at 25- 55 mph.

Any of you folks that bond the units to the transom ever have one come off?

i drilled and then slathered the screws and the surfaces with goo just incase (smaked it off a rock and run it in the nastiest water my boat will handle no problems at all
