What does a jack plate do?
Jack plates allow you to raise and lower your outboard motor so as to operate at peak performance even in shallow depths. By keeping the motor straight, as opposed to trimming, the full force of the propeller is pushing the boat forward. This eliminates the “rooster tail” effect and helps keep the boat on plane which will help increase acceleration, top-end speed, and of course, fuel economy.
What are the advantages of an electro-mechanical actuator over a hydraulic actuator?
Our electro-mechanical actuator uses no hydraulic fluid which means no filling, no leaks, and no extra hoses cluttering up your boat. Also, there is no possibility of hydraulic bleed down, our mechanical screw locks the unit in place.
What is setback?
Setback is the term for mounting your motor further back from your boat’s transom. It offers several key benefits. First, it allows the propeller to run in “cleaner” water. The water coming off the boat’s hull is somewhat aerated and moving the propeller back to less aerated water will give it more bite. Also, since the water coming off the hull is rising, setting the motor back allows you to run the motor higher in the water. Finally, setting the motor back changes the balance of the hull, at full throttle, having the shaft more level allows for maximum thrust.

Make Sure to Check All of the Connections
- Ensure pins and receptacles are not damaged
- Ensure Amphenol connections are locked tight
Check Wires
- Ensure wire coating is not damaged
- Ensure cords are not damaged
Test the Battery
Remove the motor from the unit and test it to ensure the motor is in good working condition and the shaft spins freely in both directions
With the motor removed, manually test the actuator to ensure that it moves freely
General Tips
- It is always a good idea to disconnect the battery when storing your boat for long periods of time. If possible, use of a battery tender will help ensure the battery stays charged and ready for use.
