made new braket

(1/3) > >>

jimf:
I have a997c si and I had a problem with my 2 elec motors hitting the trasducer line of sight. I try rasing the motors but they had to go up to high and I was getting prop wash and it was to slow.
So I desided to make my own braket for just under the boat in the back. I made it out of anodized metal and it is 3"x 3" and it only drops down about 2" under boat. I don't take the boat on any lakes with wood , just weedy lakes and I only have a15hp and maybe I can get up to 20miles per hour.
The company braket was in palce with 3M outdoors tape, Very sticky stuff ( home depot). I just used it to make sure thats were I want to put it. After I might use 2 part lockit expoy with 2,100 psi or JB weld 3,300psi when it drys. I think it will hold good on the boat. I don't want to screew it in the boat. never did with any of my trasducers.

the braket was off setted because the bottum of boat is not flat.

Nice mount for a home made job...  Just remember that even thought there is no wood in your lake there are plenty of other ways to "remove" the transducer from the bottom of the boat for you.  Things to keep in mind would be beaching the boat while loading and unloading if you fish by yourself, random floating stuff ( I passed a 55 gallon plastic drum the other day at 55 mph ), fishing real shallow water (bedded fish in the spring) and plenty of other unspected things.  Something else to keep in mind is I have ripped the tranducer for my 788ci off my trolling motor going 2 mph before by running the tranducer into the bottom while fishing shallow water.  Just some things to keep in mind.... I wish you luck

good job on mounting.  Related to several others posts, remember to not overtighten the mounting screw to hold the transducer in place.  Overtightening can crack the transducer hub.  You might use a couple of shock absorber washers.      chuck

Like those rubber washers ? Like the 1/4" ones. I did use one on each side.
That is the thing. I know I can rip the trasducer off if I run over something to fast but I use my boat with elec motors or gas motor 50/50 % of the time. I just hate knowing I can't use it when I'm in elec. only lakes.
Most of the time if my front trolling motor hit buttom I don't to any farer or my 2 back motors hit buttom before the boat dos.
