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 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 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 do you measure the shaft length on an outboard motor?
To measure your outboard motor shaft length, measure from the bottom of the mounting bracket where it rests on the transom to the top of the cavitation plate, this is the horizontal surface of the lower unit immediately above the propeller.
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 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 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.
What is the diameter of a Minn Kota trolling motor shaft?
The diameter of the Endura shaft is 1-1/8″ (1.125″ ).
How deep should my trolling motor be in the water?
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 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.
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.
What size shaft is on a 56 frame motor?
A 56 frame size motor will have a dimension from the rotor shaft centreline to the underside of the motor feet of 3 ½” and a shaft diameter of 5/8”.
What is shaft height motor?
The longer the motor body, the longer the distance between mounting bolt holes in the base (greater F dimension). You can figure that a 48-frame motor will have a shaft height of 48 divided by 16, or 3 in. Similarly, a 56-frame motor has a shaft height of 3.5 in.
What is the diameter of a 48 frame motor?
NEMA FRAME D* U> 48H 3 1/2 56 3 1/2 5/8@ 56H 3 1/2 5/8@ 56HZ 3 1/2 7/8.
What instrument measures Dia?
Hint: A screw gauge is an instrument that is used for measuring the diameter of thin wires and also the gauge can be used for measuring the thickness of thin metal sheets.
What tools are measuring hole depths?
Types of Depth Gauges Analog (dial) depth gauges. Digital depth gauges. Depth gauge micrometers. Depth rulers. Vernier style depth gauges.
What machines are used to measure length accurately?
Contact devices Architect’s scale. Caliper. Diagonal scale. Engineer’s scale. Feeler gauge, used in metal working to measure size of gaps. Gauge blocks. Gunter’s chain. Measuring rod.
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.
Can you convert a short shaft outboard to a long shaft?
A large outboard motor inventory is no longer needed with a Bay Long Shaft Kit. Your short shaft motor can also be sold as a long shaft with a Bay Kit. Motors can be easily converted back to fit any customers need. Bay Kits come complete with all parts needed to make the conversion.
