Have a 16ft. MV aluminum jon boat. The boat did not come with a base for the trolling motor like some i have seen. From the front casting deck to the top of the gunnel is probaly about 3- 4 inches high. I was wondering A) Do i try and find someone to make and weld on one (MORE EXPENSIVE) B)Do i make one out of wood C)Do i find some sheet metal and pop rivet one myself. ANy advice would be greatly appreciated.

Re: MOunting Trolling motor

Cheapest = make it yourself. What you make it out of and how you make it is a matter of how creative you are. Wood rots. Fiberglass lasts forever. Aluminum takes a sheet metal break to make decent bends unless you are again creative and have an assortment of angle iron and "C" clamps to do the same job. My thoughts are to buy a quick release plate. Then head to the hardware store and by four stand-offs of the appropriate length to bring the quick release plate up to whatever height you need. Secure the plate to the deck with bolts through the stand-offs, attach the other half to the motor, mate the two and your done. No welding, no bending, just a little drilling. The nice thing is that you can remove the motor in seconds to keep it safe wherever the boat is stored.

1st what type trolling motor are you using, permanent mount with a base, or a clamp on.

Re: MOunting Trolling motor

I'm having the same problem of mounting a permanent bow troller on my 14' Jon boat. The gunnel is 2" higher than the deck, so as a temporary setup I just installed a 2x6 between the deck and mount. It works fine but I want to find a piece of aluminium that'll last longer. If I can't find what I need by spring then I'll have it made for me from aluminium angle and plate.

Re: MOunting Trolling motor

I have a 40lb thrust Minn-kota all terrain foot controlled trolling motor. I was gonna go with the 2x6 idea but there is no way for me to get underneath my casting deck, cuse its closed off. I wouldn't be able to get the nuts on the bolts. How hard is it to bend sheet metal myself? I like silvertips idea, about bending the sheet metal myself. I don't think it should be to hard. ANd then riveting it to the gunnel and deck. By the way, what are standoffs? THanks for the info guys!

Re: MOunting Trolling motor

Standoffs can be anything you make them out of. A piece of copper, galvanized, or plastic pipe for example. Call them spacers if you like. You can also buy them (these are called spacers) at Lowes in plastic and various lengths.

You also don't need to get underneath the deck. Use "well nuts". These are rubber plug looking deals with a metal nut embedded in them. you drill a hole the size of the well nut. Push it in the hole. when you bolt something down on them, the nut is pulled up, expanding the rubber and therefore securing things nice and tight. Use a well nut that accepts a 1/4-inch bolt and you will be good. If you use the quick release plate the well nut also serves as vibration damper so motor noise will be cut down.

If you plan to bend somehting up, you need to make a pattern of whatever form you wish to end up with. It then must be bent in a specific sequence or you may not be able to make a cruicial bend because the previous one is in the way. it takes some thought and drawing/planning ability. You also need some fairly substantial material. If you don't have a way to make nice straight bends, you can't do this.

If you don't want to spend the money for the quick release plate, stop by a machine shop and buy a piece of 1/4 inch thick aluminum plate cut to the size for the base of your tolling motor. Then use the standoffs (spacers) and well nuts. It will be cheapest and effective although you loose the ability to quickly remove the motor. You only need to drill holes to match those on the torller and whatever pattern you need to mount the plate to the deck.

Re: MOunting Trolling motor

Now thats what im talking about! As long as i can find those well nuts, thats exactly what im gonna do! One last question. If i get some spacers how do you make the bolts fit inside of the spacers? Do you use a washer at both ends? Or do you find a spacer with about the same diameter hole through it as your bolt? THanks for the info Silvertip!

Re: MOunting Trolling motor

If you try Lowes, Home Depot, etc or even your local hardware store you can buy them with a hole through them for whatever size bolt you use. Or you can use steel or aluminum tube also at the same stores. Use a hacksaw to cut the tube to the desired length. Again, buy tube that is close to the diameter of the bolt. You don't need a washer except on the end that sits on the well nut.

Well nuts look like this:

Spacers look like this:

Well, I stopped at a welding shop today, and SURPRISE- they had exactly what I've been looking for- a piece of 2" x 6" square aluminium tubing, 35" long. PERFECT!
Now all I got to do is cut the ends to match the boat, drill a few holes and bolt everything down. Piece of cake.

COME ON SPRING! I need to catch some FISH!!!!!!!!!
