I tried and it is not coming off to easy. I don’t want to apply any more pressure on it and break it if it’s not the correct way to change it. Any pointers?

I strongly suggest using a padded vise and supporting the whole assembly with the motor elevated above the head while doing this to prevent small pieces from falling down into the motor and circuit board. It comes apart in the head. You pull off the top cover. Then the cables and cable drum come off. Then you drill out the rivets holding the pinion gear on. You can get replacement rivets from the same source as you get your bearing. They are a 1/8 rivet 5/16 or 1/2 long stainless steel pop rivet. I believe. Do not use an aluminum rivet. It will break on you under use. Do not use a steel rivet. It will rust. I bought stainless rivets from a bulk supplier, but if you are just doing one motor its easier to just pay the outrageous price for the “MotorGuide” rivets. Anyway, after you have the head apart the motor and lower shaft will slide right out of the upper shaft. Replace cup and bearing as needed. Reassemble in reverse order.
How to Identify and Resolve Common Issues ?
We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :
The safest way to increase the speed of the boat is to duplicate the propulsion system, i.e. add another battery, trolling motor, and whatever else goes with it.
Add Ground Wire Adding an external ground wire from the Minn Kota lower unit to the trolling motor battery negative/ground and depth finder battery negative/ground will help prevent interference.

However, if the shaft is too long, the propeller creates turbulence deep beneath the boat that will spook any nearby fish. And if the shaft is too short, the prop won`t be adequately submerged, which will create noisy chop in the water and also scare away the fish.
Typical trolling speeds vary from 2.4 to four kph (1.5 to 2.5 mph) for trout, and 1.9 to 2.9 kph (1.2 to 1.8 mph) for kokanee. However, when trolling plugs or bucktail lures, you can speed up to as much as 5.6 kph (3.5 mph).
As a general rule, we recommend a 110 amp hour (Ah) rating per battery for 6-8 hours of runtime. If you have a lower Amp Hour rating, you will want to calculate the runtime for your motor.
A NLGI 2 grade grease is the most commonly used in electric motor applications.
Tighten prop nut 1/4 turn past snug, [25-35 inch lbs.]. Caution: Over tightening can damage prop and bend the drive pin. Caution: DISCONNECT THE MOTOR FROM THE BATTERY BEFORE BEGINNING ANY PROP WORK OR MAINTENANCE.
Propeller pins are designed to break when the prop gets caught on debris or underwater obstructions. They are designed to break to prevent damage to the armature and other parts of the lower unit of the motor.
Once you`ve readied the new propeller, you`ll need to install it onto your boat`s shaft. To do this, start by tightening down the nut on the back of your boat`s engine until it is snug. You want to make sure that you don`t over tighten this nut as this could cause damage to your boat`s engine or drive shaft.
Removing Your Boat Propeller: Step #1
Now, you`ll need a socket, usually 1 1/16” will do the trick, but if you have a socket set, we recommend having that handy as not all sizes are the same and can vary by manufacturer.
Nuts are just as tight as when the went on. In aviation a nylon lock nut is one time use. On a boat, if you thread it on and you still feel resistance at the nylon I would say your still good to use it. I have never replaced the prop nuts on my drive.
Often times simply removing the prop, rotating it 180 degrees, and re-installing it will lessen or eliminate the incidence of vibration. If this does not correct the problem then you should contact your local Minn Kota Service Provider for an evaluation.
Submersion Rule: You`ll want the top of the motor submerged at LEAST 12″ under the water to ensure adequate power and to prevent noisy cavitation which will scare fish.
Engine calibration alters a vehicle`s engine parameters to align with the way the vehicle is used. The result is a vehicle working more cost-effectively and efficiently, which means lower fuel costs, improved safety, greater productivity, longer vehicle life, and a better bottom line.
In our experience, both MotorGuide and Minn Kota make quality products that you can count on. Both have a long tradition of making well-known trolling motors, and both lines are still manufactured in the United States.
The jumper wire used should be one size larger than the Trolling Motor lead wire. Connect positive (+) red lead (from motor) to positive (+) terminal on battery 2. Connect negative (-) black lead (from motor) to negative (-) terminal of battery 1.
The standard shaft length is 42″. To determine the right length for your boat, measure the distance from where the shaft is mounted on the deck or the transom to the water. Then add 16″ (for MotorGuide) or 20″ (for Minn Kota) and select the next closest measurement.
While engines can scare fish, trolling motors are not the same as a two-stroke outboard engine. Trolling motors are actually designed to help you move without scaring the fish, too much. However, there are some fish, such as crappie, that will be scared by a trolling motor in shallower water.
The shaft length on a trolling motor is measured from the base of the motor head down the the top of the motor compartment.
Shaft adapters and extenders attach to the end of a motor`s shaft to increase the shaft diameter, convert the shaft thread size, or increase the shaft length. These adapters provide more mounting options for motors.
For a trolling motor speed determined by a factor of prop pitch and motor R.P.M. Thrust is simply a static measurement of pushing or pulling power, and higher thrust does not necessarily mean greater speed.
A 100Ah lithium battery will last for 1.85 hours or 1 hour 51 minutes on that trolling motor at full speed.
They typically last around 2-3 years and may require some sort of maintenance.
