RE: [PSUBS-MAILIST] Minkota thrusters filled with foam



Hi Dean,

 

If your minnkota has a threaded chrome style tube you can unscrew it and drill/tap the housing right through the base of the opening below the threads. This allows you to drill the holes without taking the motor apart and keep shavings from getting inside on the magnets. You can then attach either a flexible tube over the wires back to the hull penetration (you’ll need to create a motor mount with this method) or just re-install the threaded shaft and pot the wires in the shaft.

I was quite surprised drilling and taping a hole in my little horizontal thruster.

I was going to use the flex tube and WD-40 on it.

 

The front end cone is filled with some sort of structural foam.

Needless to say this won't work to good.

 

It is a 36lb thrust Minkota, has anyone come across this?
