Trolling motor


Recommended Posts

I have a little 12 foot little fishing inflateable that i want to put a little trolling motor on the transon. My boat is about 100 pounds. I was wondering about how much thrust i would need to make it go a decint speed. Also do trolling motors come with batries and chargers and if not how much are they. Also does a motor have to be 12v to run on 12v or do they just run on a 12v, 24v, or 36v.

How much do you want to spend and what will you use this for? If, you are not planning on long-lining crank baits all day, then read on.

I put a transom mount motor (minkota, 12V, 36LB) on my 14' deep&wide lund and it was well matched. I figure the boat weighed about 1000lb fully loaded.

My advice: For your boat, set your sights on a 30lb thrust, 12V trolling motor. Any thing bigger is overkill. These are easy to find in the used ads because many people buy them for bigger boats and find they are undersized. You'll also need to purchase a 12v deep cycle marine battery. Fleet Farm sells them for around $50. Lastly, you need a low-amp charger (trickle charger) to recharge & maintain your battery. You don't want to recharge with more than 2amps. You can find these low amp chargers for cheap (under $30). The chargers get expensive when you have multiple ranging (2amp, 10amp, 70amp...).

To answer your question about voltage - yes, a 12v motor needs 12v of power, a 24v motor needs 24v and so on.

DGS has some great advice.

A 27-34# thrust Minn-Kota is available for around $80-$110 respectively.

A variable 2/6 amp charger I have also seen available for around $20.

Like DGS has stated, you want to charge deep cycle batteries slowly, otherwise heat will build up, they won't take a full charge, and the life of the battery will be shortened consequently .

A 115 amp hour battery is probably suited best for you, and will give you plenty of hours of use with such a light rig and smaller size trolling motor.

Good luck and good fishing

Every fall, I use a 27lb thrust Minnekota on a 12ft. aluminum that I converted to a duck boat. With two men, a dog, and three or four dozen decoys, the motor moves it about the same speed as I could row it. But its lots easier. For the boat you described, you probably don't want to go more than 30lb thrust, because any bigger and you'll end up with the longer shaft. The 30lb has a 30 inch shaft and the bigger ones have 36 or longer, which would get rather clumsy in a small boat. Good luck.

      On the south end...  A great week of walleye and sauger fishing on Lake of the Woods.  Lots of limits.  Good numbers of fish being caught, which includes eaters, slots and some trophy walleyes to make things interesting!    Most anglers are jigging with a frozen emerald shiner or live minnow.  Jig colors to consider are gold with a bright color such as gold / pink, gold / glow white and even gold with some tinsel.     Some reports of spinners starting to work well tipped with a minnow or crawler.  A great technique is drifting with a 2 ounce bottom bouncer and spinner rig. Fish being caught around the lake.  Trust your electronics and watch for fish.  In addition to the south shore where various schools of walleyes and saugers are living, consider the Garden Island area, Knight / Bridges Island area, and Twin Islands where good fish are being caught.   Most walleyes in that 18 - 24 foot depth.    Good pike reports.  Back bays are still holding good eaters and a few big females.  Some of the larger fish have made their way to the lake.   On the Rainy River...   Walleye anglers are finding some nice eater walleyes in the River.  There is always a number of walleyes that stay in the river all year.  Whether you like the beauty and secluded feel of the river, have a small boat or simply want to get out of the wind, the river is a great summer spot with little traffic.  Anchored up or slowly moving upstream with a jig and minnow, trolling spinners / crawlers or trolling crankbaits are all effective right now.     Smallmouth bass are plentiful in the Rainy River.  Whether you are a bass angler or simply want to mix up species, target feeder rivers, bridges, and areas with rocks.   The sturgeon season will re-open again July 1st. Up at the NW Angle...  Excellent walleye fishing this past week.  The jig and minnow is the goto bait.  Anglers using spinners with crawlers or minnows and crankbaits are catching lots of fish as well.     Structure around the many islands holding walleyes.  Shallow flats areas with current are also heating up.     Great fishing reports from both sides of the border.  NW Angle anglers boating into Canada to fish cannot possess or transport any bait, alive or dead.  Most are using jigs / plastics, artificial crawlers on spinners and crankbaits with great success.  If desired, live bait is available and can be purchased for the day just over the border via boat in Canada, check with your resort for details. This entire area is great for multispecies action.  In addition to walleyes, big pike, smallmouth bass, jumbo perch, crappies,and muskies are also being caught on a regular basis.

      We are heading up a week from Friday if anyone has walleye thoughts on the West end. Thanks!

      Fishing for Walleyes slow. Panfish are going good however.  Lots of junk floating around the lake be careful. Pontooners give the fishing boats a wide birth.

      Thanks to all that have shared reports.   Please post water temps and general area of the lake from the weekend and throughout this week.  I am heading up this weekend and water temp will play a role in our tactics.  Thanks!

      Great idea! Filming your hunts and watching the footage during the offseason is a fantastic way to stay connected to your passion. YouTube offers a wealth of non-professional hunting videos filled with tips and inspiration. Your friend's camera stands for shallow water hunting sound impressive! It's a clever way to capture memorable moments. Enjoy your hunts and happy filming!

      Fished for about 4-5 hours this weekend with the kids, all time in Big Bay. Had a mix of rainbows and pike suckers for bait. Rainbows out-fished pike suckers, and the small rainbows were bringing in fish. Caught about 12-14 fish, kept 8 for a fish fry. Biggest was 16". Limited sample says action seemed better in the morning than evening. Working 16-18' in the morning was our best run. Evening was slow. Didn't get to too many places, hit four reliable spots and caught fish in 3 outta 4.

      I generally found 65 degrees in Black Bay, and 60-62 degrees in main areas of the west end. Ideal swimming temps in my opinion, where you jump in and notice the cool and then it feels great after you swim around a bit.
