Minnkota not running full speed

Just picked up a used Minnkota Vector 80lb trolling motor off hsolist for the bowfishing boat. It runs off 24v vs the 12v system the boat was originally wired for but I put a 24v plug in the boat and wired 2 12v batteries in series and got it working. First time on the water it ran great, full speed was crazy fast and we ran at about half speed all night. Only issue was if we got into thick weeds and the prop started getting wrapped up it would pull too much current and trip the breaker in the boat. The next day I bypassed the breaker to prevent it from tripping as a temporary fix since I couldn't get a larger one in time. Got out on the water and the motor barely moves the boat when turned up to full speed. Both batteries had been hooked up to the charger all day. The battery meter on top of the motor read 100% power. Pulled the power head apart to check for debris and everything looked clean. Any ideas whats wrong with it?

If that is old school motor there are a bunch of resistors in the motor part that is in the water.  If it was drawing too much current you could have burned out something.  Take a multimeter and measure the resistance across all the wires going to the motor part from the top of the motor. 

If it is one with electronic speed control, then that isn't the problem.

are you sure you have 24 volts when you hooked up the breaker again ? Is there a chance you re hooked you reversed the wire or put it on the wrong terminal

Do you have in line fuses on the positive connection for each battery?  If so, are either of them 'popped'?

No inline fuses, there has to be 24v getting to the motor because the battery gauge on the motor head read full power. Thats the part that confuses me the most.

Call the Motor Clinic in Bloomington (952) 881-0898 - it sounds expensive to me. :)  I would try another set of batteries if you could to rule that out.  Sounds like it's only running on 1 battery.  .02

or take your multimeter and measure the voltage while running the motor even just in a plastic tub of water.   Measure as close to the motor as possible, perhaps on the back of the socket.   I am sort of suspicious of those meters on the trolling motor.   Or the battery could have a problem when loaded.

I had a similar problem with my Minnkota, it would only run up to about half speed.  Took into a shop and they found the brushes and windings all corroded due to a seal leakage.

I will do that. The motor itself is in perfect shape, I checked brushes, bearings, etc. I'm thinking its an issue either with the batteries or with the circuit board in the top of the trolling motor.

Not sure if my story will help but this is what happened to mine...

I was running my MK in heavy wind all day when I started noticing a slight burning smell. Only caught it when the wind was right. I later pulled my MK power head and noticed the wires were charred at the connection from the shaft wires to the power head. This all steamed from an old worn out BATTERY! It was the end of the year and I was going to replace the battery before next spring...one trip away!  Anyways, I was looking to replace the PDV2 power head with IPilot. I was worried that I ruined the whole motor. I cut away the charred wires and replaced the power head with IPilot and has been working great since. "If" it is your power head (circuit board) it's very easy to replace and you can order online.

Moral of my story...batteries!

      It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.

      Problems with Yetti

      By rundrave · Posted

      we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.

      By Wanderer · Posted

      I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.

      Problems with Yetti

      By rundrave · Posted

      reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
