The Detwiler manual jack plate was the first to utilize adjustment from inside the boat. The manual "On The Water" Series jack plate can be adjusted within minutes to quickly find peak performance.

The Ex-Zact Dial II is the best calibrated switch on the market for changing hydraulic jack plate heights.

The Detwiler hydraulic jack plate can travel a full 6" in 8-10 seconds making it one of the fastest on the market.

All Detwiler jack plates have been load and stress tested at outside testing facilities to insure one gets the best possible value for their dollar.

Changes the leverage angle of the boat and improves hole shot.

Improves bow lift due to leverage angle to improve speed due to less hull drag. Top end speed increases 2-4 mph in most cases.

Adjustments in engine height can be made in increments of inches vs. 1/2" to get better performance from setup.

Prop slip reduction lends to better prop efficiency....better top end speed/better fuel economy.

Changes the leverage angle of the boat and improves hole shot.

Improves bow lift due to leverage angle to improve speed due to less hull drag.

Top end speed increased due to being able to turn a larger than normal pitched prop. Hole shot is not sacrificed.Top end speed increases 3-5 mph in most cases.

One can compensate for load, water, weather conditions to get peak performance.

Prop slip reduction lends to better prop efficiency....better top end speed/better fuel economy.

Better control of the boat when fishing and boating in shallow or stumpy waters by using the hydraulic plate to lift the engine and not having to use tilt/trim.
