    I used a trolling motor for my new jon boat this summer (my first boat), but I am considering buying an outboard before next spring. So I've been looking around at some motors and accessories and saw these jack plates. This may be a stupid question for most... but what exactly does a jack plate do? I mean other then mounting your motor to it. Obviously people use these instead of mounting directly to the transom... I am just wondering why? Thanks for the help.

    They are used to lift the moter higher on the transome so the drag will decrease and you can get a little more speed. Mostly used on boats with a pad. Big motors and bass boats. \If you want to make you one for a flat bottom go into the library, Bob paul has a good article in there on making a jack plate.

    Thanks, I appreciate the help. So, if I were to put about a 10 hp motor on a 14 ft. jon boat I wouldn't need one right?

    That is correct. No need for it unless you had happened upon a motor with a real long shaft.

    Not only does it get more of the drive up out of the water for less drag, it also puts the drive a little bit farther back away from the stern of the boat. When water comes out from underneath the hull, it has a certain amount of turbulance in it...in others words...it's not "clean" water. The jack plate puts the motor and drive up and farther to the rear of the boat. This "cleaner" water makes it easier for the prop to get a grip and make more thrust.

    As Bubbakat said most are used on boats that have a pad hull. While a jackplate will increase speeds on most boats, a pad hull will see the most increase. I like them for the ability to raise the motor straight up and run shallower water.
