I want to mount a trolling motor on my 78 16ft tri-hull which I have converted the front to a floor with a swivel seat(bass boat style). I am not sure how to mount or if the trolling motor would work right mounted on the front of my trihull. Also, I am told I will probably need 24volts to power a 55-70 pound thrust motor and I don't know how to get 24volts? Any help would be awsome. thanks jaybird

Use 2 12volt batteries in series to get 24 vots.<br /><br />Take the negative of one battery and connect it to the positive of the other. The remaining 2 terminals (positive on one battery and negative on the other) will give you the 24 volts you want.

Most "boost", or "starting" batteries don't work well with long and deep draining devices, such as trolling motors. Better to use a dedicated (or two dedicated to get 24V) "deep-cycle" batteries.<br /><br />I've seen bow mount devices for the front of boats that may work. Most devices bolt to the top of the bow, so you will definitely need the long shaft trolling motors.<br /><br />Post pix.

If I were to do it over again I would have gone with 24v. It has a much lower amp draw and can last a bit longer, especially in windy conditions. Now with that said I have never actually had a problem with my 12v setup, it will just get a bit sluggish toward the end of a 10-14hr day of fishing(normal conditions).<br />Mounting it should not be a big deal but you are going to have to pick a motor before you think about how you will mount it. Every series motor has a different footprint. I would suggest a Min Kota powerdrive series. It has a very small foot print that would be easy to mount.

Minnkota has a 50 & 55 Power Drive (12V) that will work just fine on your 16 footer. I have one on a larger boat and it runs all day on a single, large deep cycle battery. The Power Drives also require very little deck space for mounting. Use a quick release plate to allow removal of the motor for theft prevention.

Upinsmoke is right on this one, buy the 55, and dont look back. Im going to buy a new motor for my 18', and Im not going to go with a 24 volt motor.

My boat is not just a 16ft boat, it is a very heavy 16ft boat as it is a old(1978) fiberglass boat with an inboard motor. Do you still think a 12V 55lb thrust will do good? By the way, thanks for replies and help!!!

Your enemy is the wind, not weight.<br /><br />If your boat is high sided, Bass boats sit lower in the water and if you go out in brisk winds sometimes, you may be better off with a 24 volt. I have a 45 # motor now, and it is pretty good for what I do mostly, so when I upgrade Im going up to a 55# but staying with 12V.

Re: 12V.....24V??

12 volt or 24 volt ?... I've run both for many years. A lot of things to consider... size, weight, draft and style of boat and how the wind effects it. Where and how you use it... is there water current, how long you will use it and how fast you want to travel. Then there's the weight, space and cost of a two battery 24 volt set up. As with boats and motors there are compromises to be made.<br /><br />I do recommend buying the biggest (power) motor for your needs. A 24 volt system is the best if you are going to use it hard but with the newer and bigger 12 volt motors they are a very good choice. My guess and it's just a guess, is a 12 volt should work just fine for you, as it does for most, as most boaters are not in heavy current. Give it a lot of thought, you want to get it right, these things cost $$$.<br /><br />Since the Minn Kota is mentioned above... In '01 I bought a Minn Kota 55 PowerDrive with AutoPilot (12 volt). It's a very good motor, doesn't take much space and I would surely buy the same motor again for the boat I am using it on (14' aluminum utility), but it does have a draw back for me (which I knew)... again compromises. I fish the Mississippi river with a lot of current and when in obstructed waters (rocks, wood, weeds, etc.) or shallow waters (just enough to float the boat) it is more of a hassle to quickly get it up and over the obstructions under power than with the other style of trolling motor (manual) where you pull on the cord to release and lift the motor with one hand while still powering and steering with the foot pedal, holding the prop surfaced just biting the water.<br /><br />You don't want to avoid these areas because your motor is more difficult to operate in.<br /><br />Two years ago I added the CoPilot to the motor (a hand held remote control). It will override the foot control or can replace it. That is a real nice addition. I also have the quick release mount. In one minute it's off, and the battery, for when I don't want to use it.<br /><br />I do see they are putting these motors on the big bass boats, but for the river, my preference would be the manual, 24 volt, cord pull up, pedal push-pull cable steering motor. I have a good 25 years experience with these boats and motors, but haven't run a 36 volt.<br /><br />With a manual you know the motor direction with a remote you may have to also look.... again compromises.
