Minn Kota Salt Water Transom Mount

Refers to how powerful the motor is. Boat weight is key when determining how much thrust you need. 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.

Indicates how much battery power your trolling motor requires. You’ll need 1 battery for every 12 volts in your trolling system. 55 lbs. of thrust or less = 12 volts, 1 battery 68-80 lbs. of thrust = 24 volts, 2 batteries 101-112 lbs. of thrust = 36 volts, 3 batteries

How do I select trolling motor shaft length?

Choosing the correct 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". In general, shaft length selection is more critical with bow-mount motors versus transom-mount motors. Most boat transoms are similar in their distance to the water, and Minn Kota’s standard transom shaft lengths should be adequate. With bow-mounted motors, there is much greater variation in shaft length requirements. 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.
