Tm Transducer On Transom?

[SissySticks]

What is the best way to mount a TM transducer puck to the transom of a boat? Anyone done this and have a method that worked well for them?

Get the transom mount hardware, new fish finders may be different, but the only difference in a trolling motor transducer and a transom transducer is the mounting hardware. You can buy the hardware to mount the transducer in either spot.

False. A trolling motor puck does not have attachment points for a transom mount. They have slots for a hose clamp.

It has always been that way.

Some adapt a transom mount transducer for trolling motor use.

 

Both of these are trolling motor pucks. one is a dual frequency 2D and the larger one is a Side Imaging puck.

The Lowrance/Eagle puck is like the 2D but about 1/2 the size--same mount system though.

So the transom mount can be put on the trolling motor, but not the other way around?

And also my apologies to the OP.

Wayne, Could you show more pictures if available, of how you have your wires rigged up on the tm shaft and back to the electronic? I'd like to see how your's compares to mine, and I'm sure it's far better. Thanks

I don't have that setup any more, that was about 2009.

 

I have a single Side Imaging transducer on the trolling motor now and it is the HDSI of which there is no puck version.

I have it attached with a Transducer Shield and Saver mount which is way better than the Humminbird trolling motor adaptor..

 

I'll describe one of the best ways to run the cable. Run it up the shaft on the prop side of the shaft to lessen the chance of being crushed if you bump into stuff.The picture shows that routing sort of.

Leave enough slack at the pivot point so the motor will turn all the way around in both directions. Once you get to the shaft clamp on the mount, run the cable along the mount to the deck. That is to keep it away from the power cord as much as possible to prevent RFI.

 

The excess cable is run under the deck, coiled into a choke (RFI prevention) and back out from under the deck to the display. The choke deal is to make about an 8" coil with the slack, twist it to form a figure 8, fold that in half to form a 4" loop and tie it up so it stays that way.

 

The attachment to the shaft has to be done so whatever you use will not pinch or crush the cable. I use plastic wire ties and put the lock where the cable is so I cannot crush the cable when tightening them (been there done that) Tape works good too.

 

 Since I fish in stumps and trees a lot, cable damage can occur where it leaves the transducer and goes around the motor to the shaft (been there done that too). I made this cable protector to prevent that and submitted it to Transducer Shield and Saver to add to their inventory. (hasn't happened yet that I know of).

This is my current installation.
