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

Greg I have potted the wires, and built a mounting bracket. I left a 1/8 brass pipe nipple sticking thru the pot material for filling the
housing. This worked great for my vertical thruster, a different model (42lb thrust) This smaller thruster would not except enough oil
so I decided to tap the holes in the nose and fill it that way. That is when I found the foam.
 
I am going to see if I can find some specs on it and go from there. This one I will probably do a failure test heheh

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?
