Bilge pump motors (Johnson)

I have had these on my kayak two years and no easy to find.

with jetskis they have through hull bearing that are sealed for the shaft to go through. Did not know if you could find them in a smaller size.

you are going to want to silicone pack those motors. I work with a robotics team, and we custom build our own thrusters. We pack them in a pvc tube, sealed at both ends. i have an instructable vide for it.

Take the motor and put it in a film canister of pvc pipe and use toliet wax to water proof it. Works well.
Please send me the instructable vide for it.
I work with a robotics team in Brazil.
Nice to meet you

I'm late to this thread but I've been researching the same thing and I have been thinking about sealing the motor in a pvc tube and having it spin a permanent magnet that will spin magnets on the outside of the tube to turn the prop shaft

. Just how "water-proof" do they need to be? Splash? Submersion? ...?

Most low voltage DC motors will run happily under water Spray with WD 40 every time you use to reduce rust risk. try it you may be supprised.
apparenrly they can work underwater but i dont know if that is true. there isnt an easy way to waterproof them because the spindle needs to spin freely, mabye you could buy specilly made ones? if you are in the uk rapid eletronics sell them for under £1.50 each!!!
