Question about Minn Kota Maxxum 70 Freshwater Bow Mount Trolling Motor

1 Answer

My trolling motor maxxum 74# thrust feels like i have broken something in the shaft. It is almost impossible to turn and everything in the head looks fine (cables,gears,etc.). What is in the shaft that could cause this and how do I disassemble the shaft to replace whatever is broken?

Here's a schematic for your motor:

I suspect the the bearings and cups are damaged and binding the tubes. Have a look at key #'s95, 78, 58, 59, 78A, 79. as these are the actual brgs and cups.
Good luck on your repair!

Burning out fuses on trolling motor at battery


not enough info. I went the the min kota website, they show four maxxum 80's at different voltages.is it a 12v 24v or larger? without a year model I'll have no reference to what wiring schematic Is the fuse connected inline with the trolling motor? what size amp fuse are you burning up? well I can give you some troubleshooting tips. tools to buy (1) amp gauge. if you are unfamilier with amp gauges make sure you get instruction book with gauge or you could burn yourself. Toubleshooting(1) Remove cover off minn kota trolling motor. black cover ontop of unit were the foot control wires go into.turn over foot control remove cover (2) check for corrosion. any exposed terminals should be cleaned.(3) go to your batteries and clean all connections. make sure the batteries are fully charged.(4) take amp gauge and test positive wire for amp draw as you tun on trollling motor and run it through all speeds. if batteries are in the rear away from trolling motor get a 2nd person to control trolling motor. if the trolling motor is more than a 12v system you will have more than one positive lead to test.GOAL. What your trying to find out is how many amps the trolling motor is really pulling. and at what speeds. under a load in the water and out of the water.how many more amps than the fuse raiting? newer trolling motors come with inline breakers not fuses so I'm guessing your using 30 amp fuses. again without more info i can only guess.

I need to replace the bearings in my Maxxum 65lb Thrust trolling motor.


If you never did this before , I strongly advise take it to a local shop....if you don't seal it correctly, you will end up buying a new one for water getting in.... I fix alot of things on my boat but not the trolling motor....your choice....GL

TOOK THE BOLTS OUT OF MINN KOTA AND CANT GET THEM IN. 2 SHORT.


Hi!
Here's a schematic:
Max 74 Bowmount
Make sure the end housing #7has a small mark in it pointed to the bottom (towards the skeg). The bolts can be a pain to line up!
Also make sure the armature is all the way forward it can go....past the brushes is the toughest part to get through and lined up. Keep it up, you'll get it!
Best of luck
Mike

Where can i get a circuit board for my minn kota foot pedal Part # is 9901-200c

You need your serial number of the trolling motor, length of shaft, and thrust poundage.

or you could call Minn Kota direct and give them the same information at 800-227-6433.

Install


Click the link below, You do need to know your serial number thrust of motor and length of shaft as well how far away from trolling motor you will install your battery. This link is on Minn Kota Motors website under FAQ you can discuss with a service rep at Minn Kota please call 800-227-6433, but you will still need the information I asked earlier to come up with the answer.
