Tom Kirkman Rod Holder PVC Trolling Motor Mount Question

I made one for my 19' Outback and for the first few trips it was performing like a champ. No wobble or shifting.

The first thing it occur, there was a severe vibration and I looked back and saw the trolling motor mount trying to lift out of the rod holder twisted inward. I watch Tom's video several times and he mention the tube should be just slightly under the "centerline". When he mention centerline, where exactly is the centerline of the 19' outback?

I took several pictures of my mount, if anyone have any suggestion especially Tom, please feel free to chime in so I make a updated version. Thank you and happy holidays everyone!

The way my design works, is by having the motor forward of the rod holder which tends to pull the mount down into the holder.You may be in a situation where the motor is pushing the mount forward and up. It's just hard to say without being able to see it in person. It's all about the geometry.

Grab the motor down at the powerhead and push it forward, like it would do if you were under power. What does it try to do?

I'm having a hard time making out the position of your mount from the photos. The motor should be attached to the forward side of the mount, not the rear. Which end of the mount, fore or aft, is your motor fastened to?

When I push the powerhead forward it does not feels like it is trying to "climb" out of the rod holder. More like the trolling motor is trying to turn right.



Motor is at the aft of my mount.

I have already started my version 2 of your mount and will move the motor forward. My question is the tube at the correct position? Still a little confuse about the center line part. Thank you.

I can't tell you that just from looking at it. As I stated in the various videos I made on this type mount, each model hull is a little different so each mount may wind up being a hair bit different in terms of the geometry.

But the motor definitely needs to be forward of the rod holder. I thought that was clear in my videos.
