Frequently Asked Questions About Gen 3 Extreme Jack Plates

How much difference does a jack plate make?

A jack plate can make a difference by helping a boat's performance by reducing drag, enhancing speed, improving fuel efficiency, all leading to a better hole shot. The specific difference a jack plate makes will depend on how well it is adjusted to suit your boat and motor.


Will a jack plate increase speed on a boat?

Yes. Jack plates often provide the ability to adjust the angle or trim of the outboard motor, which can reduce resistance. A jack plate also can help your boat have a less submerged lower unit for less drag, which can lead to increased boat speed, especially at higher throttle settings.


What does raising a jack plate do?

Raising the jack plate with the outboard motor positions the propeller higher in the water, which reduces drag, leading to improved speed and fuel efficiency. It can also create a quicker hole shot which can enhance overall boat performance. Raising a jack plate can also help protect the motor from water corrosion to extend its lifespan.
