How to mount a fishfinder transducer on a Honwave t38 ?

Hi everyone, I've been reading this forum for a good while and have taken the plunge and ordered a t38 package. With the air deck trim tabs, has anyone mounted a fish finder transducer to the transom ? What set up have you used.

Cheers,

Dave.

I have a 3.2 airdeck honwave and I usualy sit on the floor behind the seat and I am going to mount my garmin on the seat itself with quick removable set up .I find the seat is to far forward and have to use a tiller extension which is ok on flat water but out at sea feel more in control sat next to the transom and if its choppy I can hold the seat with my free hand.
sorry just re read your post your asking about the transducer not the main unit. must wake up before posting

Honwave make launch wheels that mount to the transom and go around the inflatable tabs at the rear of the transom.
If you have / or are going to buy a set of these I would get a fabrication shop to make you a metal bracket from stainless steel that is able to fit into the launch wheel transom mounting bracket. This would have a vertical metal plate at the end of it to which you could mount your transducer on.
Both transducer and launch wheel would be fully interchangeable.
I know the t38 is a heavy unit and I most certainly would want launch wheels.
Hope this makes

A few pics of launch wheels. Imagine the metal leg cut off at the rear of the trim tab with a stainless steel plate welded in an upright position parallel with the upright angle of the transom.

I ve got those wheels coming with the package. I m not so sure that there won't be a lot of flex from a transducer mounted the way you suggest. Is it something you have tried and tested ?

I ve been looking at the heavy duty suction cup mounts and trying to work out a way of mounting one on the top of the trim tab and then dropping the tranny down from the end of the tab somehow. Something along these lines but with a 90 degree drop down bar to mount the actual transducer head to:

My pal fabricated this setup for his Dory. Lower it when you need it and have it up the rest of the time for launching/landing.

transducer mount

Good idea about using the wheel mounting tube, when the wheels are in the at sea position, upside down, maybe a couple of stainless jubilee clips and a suitable bracket and the job is done?

Hi Jellyworm.
I've no experience of my earlier mentioned suggestion but from personal knowledge of the Honwave wheels you have ordered - a decent grade Stainless steel tube ain't gonna flex much with a small transducer mounted to it.
The brackets are designed to take the weight of the sib and a 60kg outboard.

With the best will in the world ....... forget the suction cup idea.
It won't work.
The transducer will constantly detach from the tab.
I am speaking from experience on this one.

Another suggestion would be to get some pressure treated wood.
Fashion it together in a L angled shape.
Have it vertical running vertically down the transom and have the horizontal hover horizontally over the trim tab so as not to chaff.
Paint it with bomb proof flow coat glass resin paint to match the Honwave transom and protect it from the salt water.
Use a G clamp to clamp it to the transom.
You can play around with the mounting position as well due to it not being screwed onto the transom.
Cheap and cheerful and removable.

I've scribbled a rough drawing.

Good luck with whatever idea you go with.

Cheers Kaman I'm liking that idea . I ve got some spare carbon fibre cloth and plenty of epoxy from a previous project so some marine ply covered in the cloth and epoxy will keep it light and strong.

I'll post the prototype up once I ve knocked it together.

Cheers for the tips and taking time to post the drawing.

Dave.
