You will want a trolling motor battery or a dual purpose. Starting battery's are not meant to be used on a trolling motor.

thanks for the ifo, I have a 14' bayliner and having the battery on the front deck, gets in the way, so could I wire it to the back with a seperate battery? thanks! Guy

Northlander is correct. You need a separate deep-cycle battery or a dual-purpose battery. As far as the wiring, I have a 14' boat with the battery in the front and a set of heavy-duty wires running down the inside to the back of the boat where I hook up the trolling motor. Be sure you use

heavy wire (8-10 gauge should be sufficient.) Also use good connectors.

I would recommend using 8-ga wire as a minimum. With a single battery (12-volt system) you need to keep the voltage drop to absolute minimum for best operation/efficiency.

Also, be SURE to put a fuse or circuit breaker as close as possible to the positive battery terminal. There are some (circuit breakers/fuse holders) that will mount directly to the battery terminal. I think something in the 30 to 50 amp range is likely appropriate. Don't want to burn down the house, ya' know...

I would definitely not go with anything smaller than 8ga.

30amps over 8ga at 12' is okay. If you go up to 16' 8ga is too small. Likewise if you stay at 12', but go to 40amps, 8ga is too small.

You can do a search online for "voltage drop" and find some handy calculators for sizing wire, or you can post your actual motor amp draw (max) and actual wire length (including all slack) and one of us can do the math for you. I need 6ga on my 15' boat due to the current draw of the motor.

I just ran wiring from the front battery to the back of the boat for a transom mount 12 volt. I used 6 gauge wire. Heavy wire, but I feel safe using it. Also installed a 40 amp breaker at the battery. I think I could have gotten by with 8 gauge, but didn't know any better. grin.gif Good luck, Junky......

      Opener was decent on Saturday and absolutely on fire Sunday. 9 eyes, three over 25 in, one at 28.5. A bunch of largemouths, some crappie and perch and a TON of bullhead. One of those weekends where your hands start to hurt.

      I'm quite happy since I'm going fishing with a pal for the first time in a long time. We plan to purchase some clothing for it, such as exclusive hoodies.

      The majority of docks can't be put it. Water is over the top of pretty much every permanent dock.  Very few docks are in.

      Crappies are all up shallow in the south metro. Caught this one shore fishing with a beetle spin from a more secluded lake without much access. All of the crappies were between 7-9 inches with this 11.5" being the exception

      A co-worker reported they had some the best fishing ever on V last weekend.  Trolling 6-8 feet in the morning with HJ10’s.  Where the water temps were in the mid/low 50’s

      Those campsites are right across the water from us. Seem pretty well protected and I haven't heard of challenging over there. Holiday weekends they fill up very fast

      My son camped on Hinsdale with his aluminum runabout. Nice site but walking across the hull parked on uneven ground he separated a couple of the rivets.

      Thanks "Skunked Again!" I searched old posts and it sounds like my fiberglass boat might not be the best rig for Hinsdale. Still, would appreciate more advice/input.

      I don't know about either of them, but welcome to the forum.

      I destroyed my main propeller saving a neighbors dock section from ramming my other neighbor's dock. Definitely watch out for each other out there.   Raven77 - on the plus side of the high water, the floating swim platform that you sold me the other year was able to just float off of the rocks that I had beached it on. No need to do any heavy lifting this season! I'm glad that I tied it to a tree as usual.
