One of the great jobs in the Man Cave is rigging, maintaining and working on our boats. We love working on tackle but there is something special about boat work. Whether it's a new one like the Polar Kraft TX , the Ranger Z or even the old washtub, the Ranger Banshee , there is always something new to add or something to do on them to make them work more effectively. All of us at Wired2Fish are detail oriented, love challenges and that carries over to our equipment. Installing new electronics, shallow water anchors, or our recent project, changing a 12 volt trolling motor to a 24 volt one takes careful planning. Just about every job is step by step procedure and neatness counts.
Installing new electronics, shallow water anchors, or our recent project, changing a 12 volt trolling motor to a 24 volt one takes careful planning.
Just about every job is step by step procedure and neatness counts. One of the challenges with most boats is batteries due to the weight and space they require. This boat was rigged with a 12 volt trolling motor and we are converting to a 24 volt system and different motor. Polar Kraft supplies ample raceways for hoses and cables so changing from the 12 volt system to a 24 volt system was not difficult but did take a little engineering. The wiring provided is neatly run but because the Minn Kota Edge 45 is 12 volt both the positive and negative leads were run to the same compartment.
Connecting two wires means utilizing a butt splice and shrink tubing. It's always good to grease this connection inside the butt splice to keep corrosion from occurring down the road as well.
Trolling motor hook up
Hooking up the batteries is the next step. Trolling motor lead will have positive wire run to the positive lead on battery one and the negative lead on battery two. When you enchant people, you fill them with delight and yourself in return.Mounting a Fish Finder On A Trolling Motor
For electric trolling motors do I need to hook any thing else besides hooking the trolling motor to the battery? Transom and bow mount should be the same? I am wondering if I can directly hook it to the battery without any fuses or anything.
No you need a in line fuse. We use a trailer type harness with a 30 amp fuse. Reasonably priced fuses can be hard to find. There are reasonably priced circuit breakers available. For a 16 foot boat, a 24 volt should do the job. Also, most people separate their main motor battery from their trolling motor battery.
If I had both connected to one battery, then I would definitely use an inline fuse. If the connection to the battery is a clip, like on jumper cables then you probably don't need a breaker since if something shorts you can just pull the clip off, plus the connection is more out in the open.
Wiring Batteries for Trolling Motors
Agree with the breaker vs a fuse. Most of those inline fuse piggy tail things use like 14 gauge wire and your trolling motor is probably more like 8 gauge. Plus if you blow the breaker, you just reset it. No need to carry around backup fuses. I'm guessing your talking about a 16 foot aluminum boat with some bench seats?
I have a My 12 volt 55lb minnkota gets that thing moving and can last a whole weekend with moderate use. A 36 volt system seems like overkill on that boat. Sorry guys I meant 24 volts instead of 36 volts.
So my question is if I put circuit breakers on the batteries, do I need to put a circuit breaker on each of the two batteries for 24 volts? Even 24v might be overkill. If you've got the space for two batteries, go for it. But I think you'll be fine with a 12 volt system on that boat. We choose to fuse all our batteries to prevent burning up the rest of our electronics. When I sold the Rebel and bought my Sylvan Adventurer with console I transferred the 40pd to the bow and used it for many years.
Even though the Sylvan was quite a bit more boat, most of the time the 40pd was plenty unless the wind was over about 20mph then it had to work pretty hard. In fact, the only reason I upgraded to the 12v 55pd last year was because my brother-in-law upgraded his and I got his 55pd for a fair price.
The biggest advantage of 24v over 12 volt all else being equal is that you can get by on much smaller wire and fusing.
A 12v 55pd motor will draw about twice the current of a 24v 55pd under the same load conditions. We have a 70 24 volt for the transom but don't use it that much, in fact it often isn't even on the boat.
We keep different jumper wires in our battery compartment to change from 2 rigged series as 12 volt or to change over to 24 volt system. One thing to be sure of is using the right gauge of wire. You need to be a member in order to leave a comment.
