View Full Version : Trolling motor question

I usually slow troll for crappie and striper but both of my old trolling motors are too strong. I've got a 14 foot V-hull jon with a good bit of weight on board. I'm 300lbs, my fishing partner goes about 250, plus all the gear.

One motor is a Shakespeare Sigma. It's about 25 years old, 25lb. thrust, and it has 3 forward speeds. The other is a Motor Guide, about 15 years old, 34lb. thrust with 5 forward speeds. Both of them on their lowest setting is WAY too fast. I went striper fishing about a month ago and I had a bunch of shad water skiing up behind the boat.

Does anyone know of a simple way to slow them down or of another $100-$200 trolling motor I could buy to fix the problem? Can anyone help?

Turn them around and troll backwards. The flat transom slows down the boat.

look on the 5 or 6 page for a listing (motorguide speed contol) It has a circuit that can be built to control speed. if you or someone you know can built it. It is posted by cane pole

good to see someone else out there besides myself that uses old equipment but it is still good, use plastic buckets of different sizes, like driftsocks don't have to be very big

i was going to suggest a drift sock. i have also heard of people using buckets for lighter boats.

Hey there kid, What you need is a Maximizer by Minn-Kota. There are still a few floating around on E-Bay from time to time. Here is a pic of mine.

I can dial mine so slow that you can count the revolutions of the blade! I also spiderrig with slip corks and I can set it so slow that the corks hardly ripple the water!
I just set the speed and leave it running all day...just steer!!:)

Can you buy the Maximizer new or did they discontinue them? I checked ebay and couldn't find one.

Take a dremel tool or file and start shaving down the prop.

Good idea TwainGang. Might be the best idea I've heard yet.

Hey Kid, They haven't made them in over 15 years. But about once a month 1 or 2 will show up on E-Bay. Most are new never used! Expect to pay 100.00 to 150.00+
Just keep checking..one will show up!

you might be able to take a regular 120 volt rheostat (like one used on a ceiling fan in a house) from Lowes and wire it inline with your trolling motor. I am sure it would work with 12 volt, the question is, how long would it last? I would bet money it would work just fine and would only cost a couple of bucks to find out. Don't trim your blade as you will need it for full power at times.

I wouldn't recomend trimming the prop down either, you may get into some wind and need it. I would recomend something like the Maximizer or a drift sock or two.(cost more than a bucket but store alot smaller).

this is not trolling motor related (sorry) Would the buckets/drift socks work to slow down my 25 horse johnson ?

Drage a couple 5 gallon buckets behind you or get a Drift Sock.

The rheostat will drop the voltage to the motor and up the current. Can cause the motor to overheat. Trimming the prop can do the same thing.

I agree with CatFan, don't use a dimmer switch or anything like that. I hear you will burn your trolling motor up.
I had an electronics buddy of mine open up my Maximizer and he said it was pretty complicated what they were doing to reduce the power. It also has a large aluminum heat sink on the back so it must produce a lot of heat.

The Maxximizer pulses the battery power on and off very rapidly to give variable speeds. The FETs that do the pulsing get very hot. That pulsing is the reason you sometimes get fishfinder interference with digital trolling motors.

Somewhat. Biggest problem with RFI interference is tying the transducer wires to the TM battery cable (to make things look pretty) and another is running the sonar off the tm battery.
