Garmin Transducer Mount for 7/8 inch tube by scottmi

Last crawled date: 3 years, 1 month ago

Continuing the collection of Grumman Aluminum Canoe toprail attachments, such as this rod holder and this fishfinder mount.
This is a side-of-the-canoe mount for a fishfinder transducer. The particular transducer for this is the Garmin GT20-TM and a 7/8 O.D. tube (I used an old mountain bike handlebar).
Printed parts consist of the toprail mount compents, the transducer-to-tube bracket, and a cable gland (printed in TPU) to protect the transducer cable from the tube edges at the top.
In addition to the 3d printed parts, hardware needed:
one 7/8" tube
one 2 1/2" clevis pin and retaining clip
two 2" 10-24 pan head screws with wingnuts, washers, and internal-tooth lock washers.
(alternative: if you print toprail outboard version 2, requires two 1" 10-24 pan head screws and nylock nuts, instead)
one 1 1/2" 10-24 pan head screw, rubber washer and nylock nut for the transducer-to-tube bracket (I used hardware that came with the transducer).
Fusion 360 file included if you wish to customize the railmount for your application.
The transducer-to-tube bracket is a remix of jabixby's design and can be customized at onshape.
