After taking forever to get through a draw bridge in the early afternoon then smacking a poorly maintained dock, I thought about a simple trolling motor on the 16. Here is what I have in mind.
I'm looking at the following trolling motor set-up for a Hobie 16
1. Machining a a derlin block which adapts a tiller motor shaft to the Hobie 16 crossbar
2. Gutting a trolling motor or just buying repair parts for motor, prop and shaft
3. Trimming shaft to appropriate height installing a permanent stop
4. Epoxy keyway to shaft to prevent motor from turning
5. Install an adjustable locking collar which allows motor to raise up and down
6. Install one or two Shorai LiFePO4 batteries in a floating neoprene/foam bag with speed control and waterproof plug to motor head
The Shorai batteries are designed as starting batteries, however the chemistry should work well in a deep cycle application. I'm just unsure as to the charge control circuitry in the battery. I sell these batteries and can save a few bucks testing one for this application. The motor with prop and shaft from a trolling motor is affordable, especially how higher range product.
I'll document my progress and share results, but have the following needs:
1. Anyone use an electric trolling motor on a Hobie 16? Models? Results? Published thrust numbers?
2. Anyone use a fixed motor while retaining rudder steerage?
3. Anyone with expertise and ability to make the block rotate so the motor shaft need not protrude when not in use?
Post if you are interested in such a project.
