transom mount transducer pole and bracket

[senkosam]

Other than my Tracker fishing boat, I own a few other smaller boats that I can launch on waters that don't have a decent launch. One 12' Jon and a 10' semi-V are loaded on a flat bed with a winch that allows me to crank those boats at a steep angle up onto the trailer. Problem is: I like to switch trolling motors. The 62# thrust is pretty heavy and usually attached to the larger boat permanently; the smaller 30# thrust is ready to install on the smaller boat used for smaller lakes and crappy launches.

Rather than change transducer mounts between trolling motors at the bottom of either with a bracket, I came up with a cheap way to be able to mount them using a pvc pipe and transom mount clamps. On-line, a mounting pole mount goes for $50 - $360. Mine costs less than $10 because I already had some 3/4" PVC pipe laying around and a broom clamp on Amazon is 4/$5. PVC pipe T's cost $6/3.

A clamp is attached with two screws on each transom.
The transducer is attached to a small section of PVC pipe that fits into a T at the bottom of the pipe. Another small section of PVC is attached to the other side of the T to keep the pole vertical.
The transducer wire it attached to the pole using two zip ties.
The pole is clamped to either transom mounted clamps.

Now I can switch boat trolling motors and not have the transducer clamped to either of them. Plus, when mounted on the bottom of the trolling motor, a depth off set on the sonar must be adjusted for true depth or it will read shallower. The PVC pole can be slide up to just below the surface and when I row in shallow areas with motor up, the transducer is above the bottom of the boat hull behind the transom and can't get weeded up.

Of course the pole clamp can be attached anywhere on the hull.
Note: a slight angle of the transducer doesn't affect reading the depth or seeing fish.
