Minn Kota have designed a special line of motors for use in salt or brackish water. The Minn Kota® Riptide® trolling motors have a number of "saltwater-engineered" enhancements, including stainless steel hardware, sealed electrical connections and an advanced painting process for improved corrosion protection. Using any of our standard Minn Kota motors in saltwater may dramatically reduce the life of the motor and voids manufacturer’s warranty. To extend the life of your Minn Kota Riptide saltwater trolling motor, thoroughly rinse the motor with freshwater after every use in saltwater and store indoors. Never leave the motor submerged in saltwater when the boat is moored.
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 center of the motor section should be submerged 9". Most boat transoms are similar in their distance to the water, and Minn Kota®’s standard transom shaft lengths should be adequate. Measure down from the mounting surface of the transom. 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.
|Transom to waterline||Recommended Shaft Length|
|0" - 10"||30"|
|10" - 16"||36"|
|16" - 22"||42"|
|Over 22"||Contact Us|
Minimum clearance required from spine of outboard to end of cavitation plate (see diagram). Cavitation plate to waterline 13" (minimum).
1 = 7-1/4"
2 = 3" (80EM/101EM), 3-3/4" (55EM)
3 = 13"
The battery is a critical element of your electric motor system. A high-quality deep cycle marine battery should always be used. Unlike automobile batteries, deep cycle marine batteries are designed to be run down to a discharged state and then recharged. (To extend the life of your battery, always recharge after use. Most trolling motor batteries fail due to lack of proper charging.)
Thrust is a static measurement in pounds of our motors pushing or pulling power.
Many people think that the more pounds of thrust they are getting, the faster the boat will go. This is not exactly true. With trolling motors and outboard motors, boat speed (and acceleration) depends on horsepower and prop pitch. By changing prop pitch, you can trade acceleration for top speed. Our trolling motors have props designed for maximum acceleration. When you hit the power, the boat responds immediately. This also allows you to hold the boat in high wind conditions. Top speed with our motors and props is about 5 mph. Small boats will reach this speed with most of our motors. Larger boats require our largest motors to approach this speed. Comparing our motors to gasoline outboards is difficult because most outboard props are designed for much higher speed.
