Does shaft length matter on trolling motor?
Choosing the correct trolling motor shaft length is important so that the angler’s electric motor does not cavitate, creating fish-spooking noise. The rule of thumb is that the top of the motor section should be submerged 12″.
How long should a transom trolling motor shaft be?
For transom motors, shaft length is generally between 30″ to 42″, depending on boat length.
How far should 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 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 your 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.
Can I put a longer shaft on my Minn Kota 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 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.
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 far below a boat should the prop be?
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.
How does Minn Kota measure shaft length?
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 shaft length.
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 long will a 24v trolling motor last?
This will give you maximum speed and power and is often necessary on a large boat, or in strong winds. Thus, if you operate your trolling motor at maximum speed, you will typically get about 2 hours of use from a fully charged pair of “average” batteries. Possibly 4 hours of use for the larger extra capacity batteries.
Will a 55 lb thrust trolling motor?
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.
What size battery do I need for a 55 lb thrust trolling motor?
For a 55 lb thrust in a trolling motor, you will at least need the battery size of 240Ah rating. Depending on the speed, you will be using approximately 20-40 amps.
How can I speed up my trolling motor?
Table Of Contents 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 many pounds of thrust do I need for a trolling motor?
General rule of thumb: you need at least 2 lbs. of thrust for every 100 lbs. of fully-loaded boat weight (people and gear included). If things like wind or current are major factors where you fish, you’ll want a little extra thrust.
Can you shorten Minn Kota Terrova shaft?
Cut the amount off you want. Be careful not to cut any wires when cutting the shaft. I used a small metal pipe to slide down in the shaft to keep from cutting the wires. After cutting the shaft shorten the wires and put the head back on.
Can you shorten an ultrex shaft?
Can you cut the shaft length on an Ultrex? Yes you can, but you have to be careful not to cut the wires and you have to re drill the the head screw holes in the head. I recommend you bring to a Authorized Service Center to get this done because if you do it yourself it will void the warranty on the troll motor.
What is the diameter of a Minn Kota trolling motor shaft?
The diameter of the Endura shaft is 1-1/8″ (1.125″ ).
