I failed! :( Up to and including baptizing a brand new trolling motor in the lake.

Sorry Tom, I let you down.

I made the mount for my outback and mounted a 30# Endura C2 to it. I made it out of 1 1/4" PVC.

Issue 1: The home depot conduit clamps I bought are crap. the motor yaws left to right with ease. I can try to tighten them up more, but I think I need a better solution because there were very tight before lake.

Issue 2: The motor rolls left to right. I had tightened those clamps up pretty tight on the PVC CAP, but I must have made the bolt holes a little too big. That combined with the yaw movement kicks the motor up and left making the tiller roll into my body (its mounted on left side of kayak.)

Issue 3: I wont tell you how the motor went into the water (too painful) but on that note, is there anything to be concern about with getting the motor head/controller wet? Thankfully it was not connected to the battery when this occurred. also, I glad I could grab it in time otherwise davey jones would be having himself a nice new motor!

NOTE: The aforementioned issues happened at speeds 3 and greater. Slow speed appeared to work ok aside from yaw issue.

Questions:

1.What specific clamps should I use to clamp motor?
2.use electrical tape to tighten up mount in hobie rod holder slot?
3.How far below the hull should I mount the motor?

I covered these items in one of the YouTube videos I made, and also mentioned several times that the geometry of the tubes is very important in order for the mount to work properly.

I'll have to go into my channel and find the video that has the specifics. Will try to find that for you this afternoon.

Here is the video that shows and explains the mount in detail:

Now there are some things you're going to have to fiddle with and decide for yourself. There are minor differences between these plastic hulls so unless you make the adjustable model shown, you'll have to tune and tweak the unit to fit your particular hull.

I think I covered most of what you've asked in the video but if not, respond back and I'll do what I can to help.

I just went through the middle. Seems ok so far. I can release it, pull it out and swap it with my mirage drive quickly. Stows away in front hatch well without the liner. Pardon the mud.

Very clever, and mud is good! :) What brand & thrust of motor? How did you mount the shaft to use the Mirage fittings?

I drilled a hole through the cassette, installed rubber grommets with marine goop, then I took the head off the trolling motor slid the shaft through a couple of times, made some jokes about it, then I wired a Minn Kota plug up, and finally put it all back together. Rewind, first I took it all apart, naval jellied it, sand, painted, and clear coated it.

Thrust I'm not sure of as it was given to me and had nothing indicating thrust on the motor.

Awesome!

I would love to either buy one from you for a transducer for my Hobie Outback or have you post the plans with the correct geometry.
I would much rather buy one from you than have to go through the trial and error finding the correct geometry.
When you decide to sell them, I and probably a zillion kayak owners will be ready to buy!
Thanks for sharing a great idea.
I have no doubt someone will be trying to make these and sell them on ebay soon. I hope it is you!

Just made my 1st attempt at this mount and guess I need to call it a failure.
without the motor on it felt solid pushing toward the rear but the slightest pressure pushing forward would make the whole thing turn and pull out from the rear side. I then decided to add a coupler to the front side between the T and the cap (to make it longer and not be able to shift) and add some tape around the cap to compensate for the curve in the hull.

That made it feel solid when pushing in both directions! But after putting the motor on it just seems to flex to much when pushing on the motor in either direction. Im using an endura 30 (older style) with the transom mount removed and shaft cut down to 18 inches.

Not sure if the motor is to heavy for this mount or not but with shaft cut down and transom mount removed it only weighs 10 pounds. Not sure how acurate that weight is tho cause i just used a bathroom scale. Is the 18 or 24 pound sevlor or watersnake that much lighter?? anyone have any pics comparing the endura 30 & 18 sevlor or water snake?

Im not giving up though and will make the next one with threaded couplings so it can adjust and find the correct angles.

Unfortunately dry fitting PVC before glueing is pretty much impossible unless someone knows something i dont know.

By the way, this going on a 2011 outback.

Here's one I made... not quite as simple as Tom's but it won't come out!

If you get the angles and lengths correct the one I designed won't budge. But as I said, it needs to be very close to exact.

You can test fit PVC if you'll spend just a little time sanding out the fittings to the pipe pieces will slip in and slip out. It doesn't take much - just enough so that they won't jam solidly in place.

My second attempt was much better and is rock solid. I used threaded schedule 80 Just like the one Tom shows in one of his videos. After I got it set I put an aluminum screw through the threaded section so it wont move. Figured that may also work as a shear pin if I hit something hard enough. I also went ahead and added screws to all the other joints for added strength just in case. Cant wait to give it a trial run.

Fantastic. Just remember, if you do hit something, you'd prefer to have the mount break rather than the boat! The "shear pin" may be a good idea.

Report back on how it all works on the water. Sounds like you're in for a good time.
