Hi Tarek,I would have to say that Minn Kota motors are the preferred choice. I am using 20 year old motors still with no problems. Hank

Hi guys,
I am building a Dry Ambient Submarine and I been having trouble finding a
suitable Motors for it, as I don't want to spend 1000s of $ on each motor.
I am sure that the topic has been brought up many times before, but I would
like to enquire about the best Trolling Motor
that can be filled with OIL in order to withstand 40 meters Depth of Water.
Appreciate any help in this matter.

Hi Rick,
Yes, the standard Min kota controller has reverse. Its just a potentiometer
on a knob.
I went for 24v min kota rip tide 80's. Wish I had gone for the 101's to be
honest.
I have the aft thruster rigged with the controller at the side of the seat,
so I set the power and trundle off. I tend to use the aft thruster for
surface driving or slow seabed cruising, so its ok where it is. Then I use
the side thrusters while submerged for manouvering.
Works ok for me.
The pots on the controllers are on a ribbon cable. I didn't dare cut them
to extend to anything more useful, although I suspect it would work.
To be honest, that's why I changed the side thrusters to simple on\off
relays. The pots were to complicated to move.
Got a couple of links here on my site.
regards
James
This was how I had it originally. Was awkward to use side thrusters.

Hi Ian,The gears you made for me arrived, and they are amazing! ?I had no
idea the fine detail capability. ?The timing is perfect also, as I have just
finished the gripper and need the wrist gears to complete the connection. ?I
might have it put together today for a test.Thank you againHank

Well done Ian.
I have posted this before. It is of 3d propeller testing done here in
Auckland.
Their preference in the end was polycarbonate!

Ian,The gears seem pretty tough, and I am sure they will stand up due ?to
the thickness. ?They machine nicely also, I was worried when I put the gear
in the lathe chuck, but is was fine. ?I machined the bore out so it would
slide nicely. ?Pitty I don't have the wrist drive motor yet ;-( ?Hank
