Mounting options for a trolling motor/Minn Kota

Thread starter #1
I just ordered a Minn Kota 40#....as far as mounting options I would prefer no holes. Can I just glue 2 layers of oak ply to the transom on the inner and outside? Any suggestions on batteries? Do these lead batteries die after hitting the water?

Experience tells me you want that motor mount to be strong and secure. The torque that a trolling motor puts out is surprising when you're docking, for instance, and quickly go from full forward to full reverse.

Wouldn't using glue leave a scar on the hull if you remove the plywood later? Here's a pic of the Minn Kota mount I made for my 55# motor that I'm using now. Four stainless bolts and wing nuts. Used solid oak and Minwax Helmsman spar urathane to seal. The other great bright work on the stern is cosmetic, from the previous owner. I just worked around it.

A 40# motor is a great choice for this boat.

Are you planning on motoring quite a bit, or just to get in and out of your launch area?

I've experimented with all sorts of setups on sailboats this size... 28 to 80 lbs thrust, 12 and 24 volts, 1 and 2 batteries, Minn Kota and MotorGuide... circuit breakers, various wire types, varying mounting positions and methods, etc. etc.

Looks simple enough. I was trying to avoid adding another set of holes in the hull for water to get into. I assume those holes go to the inside of the hull with washers? It is mostly for getting in and out of the dock or back to the dock if the wind picks up too much or dies. I also though a marine batter from Walmart or Costco would be a better option than the Maxx.

I used 6 gauge Temco Easy-Flex welding cable. Very flexible and durable. You can buy it by-the-foot on Fleabay.

I fished the cable under the cockpit bench to the hatch area, using a telescoping dock hook. This required climbing all the way inside the hatch area, which was not very fun for me.

I used Anderson electrical plugs as well, rated for 50A. Industrial strength stuff.

Probably overkill, but better too much than too little.

I really like that wood working on the transom! I would like to do the same on my A16 and possibly Capri. Could you post more pictures from the back side and cockpit?

Strange, when I tried to add some pics it says "The uploaded file is too large for the server to process." But they're way below the file size limit.
