How To Measure Shaft Length On Trolling Motor

The shaft length on a trolling motor is measured from the base of the motor head down the the top of the motor compartment.

How do you measure the shaft length on a Minn Kota trolling motor?

Measure down from the mounting surface of the transom or bow to the water level. Add 5″ to waterline measurement for fishing in rough water. Add 12″ to waterline measurement for steering a hand control motor while standing. Use this measurement and the tables below to find the appropriate trolling motor shaft length.

How do you measure the shaft length on a bow mount trolling motor?

Bow Mount Shaft Length Start by measuring the distance from the horizontal mounting point on the bow to the waterline, then add 20″ to this measurement. Generally, you will want a shaft length that is equal to or greater than this sum, but not less.

Can a trolling motor shaft be too long?

A trolling motor shaft can be too long. If the trolling motor shaft is too long, you risk the propeller hitting bottom or the inability to stow the motor properly. Too long of a shaft can not only damage the propeller but also the rest of the motor and the environment beneath the water as well.

How long should the shaft be on a trolling motor?

How do I select trolling motor shaft length? TRANSOM TO WATERLINE RECOMMENDED SHAFT LENGTH 0″ – 10″ 30″ 10″ – 16″ 36″ 16″ – 20″ 42″ Over 22″ Consult Factory.

How far in the water should a trolling motor be?

A trolling motor’s ideal propeller should be at a depth that keeps about 6 inches of water above the blades. In other words, the centerline of the motor and the prop shaft should be about 12-18 inches below the waterline, depending on the make, model and dimensions of the trolling motor.

How do I know what size trolling motor I need?

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.

Can you change shaft length on trolling motor?

While it would be cost-prohibitive to lengthen the shaft of any trolling motor, yes, in some cases the shaft of a trolling motor can be shortened. Only models from the below motors families are capable of having their motor shafts shortened: Endura.

How do you measure the diameter of an electric motor shaft?

The frame number relates to the “D” dimension (distance from center of shaft to center bottom of mount). For a two digit frame divide the frame number by 16 to arrive at this dimension. For example, in the two-digit 56 frame, the “D” dimension is 3½” (56 divided by 16 = 3½”).

What tool do you use to measure the outer diameter of shaft?

Slide Calipers: A tool used to measure the inside and outside distance (diameter) and depth of a feature. Different models exist such as digital, dial and vernier calipers.

How is shaft width measured?

The shaft width is measured at the greatest measurable circumference around the shaft of the boot. This applies to mid-high and high boots, and is most often measured in the calves.

What is the diameter of a Minn Kota trolling motor shaft?

The diameter of the Endura shaft is 1-1/8″ (1.125″ ).

How big of a boat can a trolling motor push?

Trolling Motor Thrust Guide Boat Weight (lbs) 1,500 2,500 Boat Length 14-16′ 18′ Minimum Thrust 55 70 Performance Thrust* 55 80 Motor Voltage 12v 24v.

Where is the model number on a Minn Kota?

The serial number is located on the top of the transom bracket.

How deep should my prop be in the water?

If you have a short shaft motor, the top most part of the transom and the lower most part of the boat should be about 15 to 16 inches. For a long shaft, I think 20 to 21 inches is correct.

Can a trolling motor push a pontoon boat?

Do trolling motors work well with pontoon boats? Yes, they work well with most pontoon boats as long as you select the right one for your boat. The right one depends on two factors: the right shaft length and the right amount of thrust.

How fast will a 55 lb thrust trolling motor go?

Assuming perfect riding conditions, the use of the best fuel i.e. the distillate marine diesel, and moderate load, 55-pound trolling motors are likely to attain a maximum speed of only 5 miles per hour. This would take around two hours for the deep cycle battery charge to get completely depleted.

How can I make my trolling motor faster?

Make Your Trolling Motor Faster Make Your Trolling Motor Faster. Change the Battery. Reduce the Load of the Canoe. Fix a more Streamlined Propeller. Put on Lighter Attire. Replace the Existing Motor. Conclusion.

How do you know if your outboard is too high?

Too high usually results in low water pressure, prop letting go in turns, or lack of bow lift are usually the telltale signs. Sometimes porpoising is caused by too much bow lift and dropping the motor will give it more bite and make it worse.

What is the strongest trolling motor?

Minn Kota has introduced the most powerful trolling motor on the market featuring 112 pounds of thrust.

Will 2 trolling motors make you go faster?

Two motors in the back will just push the bow a little higher in the air, and the stern will dig in deeper, slowing you down. The boat will be faster with a trolling motor if it’s level in the water.

How do I know if my boat motor is long or short shaft?

Measure from the top of your transom to the bottom of your keel. If it is from 15″ to 17″ long you’ll need to get a Tohatsu outboard with a “short” shaft. If it is from 20″ to 22″ long you’ll need our “long” shaft outboard.

Can you run a short shaft outboard on a 20 inch transom?

zike Elite Refuge Member If you set the motor back far enough without jacking it up, a short shaft will work on a 20″ transom. Never argue with idiots as they will do nothing but bring you down to their level and then beat you with experience.

What is the difference between a short shaft and a long shaft outboard motor?

If your boat has a Transom Height 15″-16″ you will need short shaft and if it is 20″-21″ you will require long shaft engine. Auxiliary engines for yachts usually require a long shaft engine so as to make sure the propeller remains well submerged when the boat is in a seaway.
