Hi All,

I'm building a simple small sub and was hoping to use an off the shelf
motor, but of course I'll need to waterproof it. Any ideas, or a FAQ that
I can reference that will get me on the right track?

TIA
Steve

if you're not running the boat in saltwater...why not run the motor wet? I
understand a number of folks do so.

When running the motor wet I found it enhances the overall lifetime of the
motor when flushing it whilst it is running with acrylic spray. I did this
now four times with the motors I tried for my snuggle Revell S-100 until I
found a model suiting the ship by power, noise and weight. I had them
running 2 days from a PC's PSU until the acrylic had dried fully - all were
and are fully operational so far.

Apparently i'd suggest looking for a short propshaft - fill it with grease
and then you can put the motor inside the waterproof electronics-module -
My propshafts prooved to be watertight even after loosing a ship for almost
a week in a rosebush at a lake until I rented a small canoe to pick the
ship up.

Hi All,

Thanks for the input, running them wet will be the quickest (and cheapest)
solution.

Has anyone played with magnetic coupling on small motors?
