Hi Phil - I should check that out. I need a specific size of 14 spline coupler... wondered if I could salvage/adapt the crank end from a dead outboard from Gilbert's marine...

---

Anyway: success!

Then: failure!

The good news is: I slapped together a wooden motor mount, coupled & aligned everything as best as possible, connected the jumper cables and it whirred happily away with a minimum of vibration.

On 12v in gear there wasn't enough thrust to move the boat against a 8-10 knot breeze (guessing). No surprise there - really wasn't expecting it to. (I just slacked the dock lines and played around without leaving the slip. The wind was on the nose, pushing me back in.)

So I stepped it up to 24v and the thrust seemed more promising... briefly ... until the coupler split! Then it spun uselessly. I may attempt a repair/reinforcement and try 24v again tomorrow.

It looks like at 12v it will only be useful in calm flat conditions, much like the electric trolling motor. I'll need 36 or 48v to get any serious push from it.

Will post a bunch of pics tomorrow showing what I've done so far.
