Scott.  I would try one of the MC 101 motor controllers for each vertical thruster.  They should work well for this application.  The motor controller has a soft start which should solve the fuse blowing.  You don't need a reversing contactor with these controllers.  When the pot is near the center of its taper (2.5vdc) the motor to the thruster (10AWG) are also connected with 1/4" spade connectors.

Alec,

I am pretty sure that is correct. The side thrusters are 14.5 amp 36V and I believe 1/3 horse and the rear thruster is 74 amp 36 volt and 3 horse. I may have to take them apart to look at the plates on them again. The problem I am having is the spike from on/off in either forward or reverse frequently pops the fuse. Is a motor controller the best way to fix this or is there a better way such as a capacitor? DC electrical motors and engineering are my two weak subjects in submarines.

Thank you,

Scott Waters
