Why a JackPlate?

Why a JackPlate / Performance Plate / FAQ's?


If you are needing to lower your engine into the water you can not use a JackPlate because a jackplate only raises an engine. A Drop Down Plate is the plate best suited for lowering engines, click here for more information


A jack plate will compensate for a long shaft engine!

Does Your Boat Need a Jackplate? For this one, we consulted our network of industry professionals. Their responses were all varying degrees of a resounding YES. But how can you tell if your boat would benefit from a jackplate? What are some of the symptoms?

  • Poor Holeshot
  • Your outboard’s not perpendicular (straight up & down) in relation to the water at top speed.
  • If you can trim the engine all the way up without the prop letting go or with no appreciable loss of water pressure at full throttle.
  • The hull doesn’t seem to “lift” like it should.

Boats rigged with jackplates, but otherwise identical to yours, turn higher-pitch props and perform better

Keep in mind that these characteristics can also be indications of other, more serious problems, but if you’re experiencing any or all of the above, your boat could be a good candidate for a jackplate implant.

What is a Performance Plate?


The performance plate option is a great add-on accessory to your jackplate! It is a solid aluminum plate we fabricate and install onto the bottom of a jackplate, closing off the cavity of your jackplate on the bottom so that water can not spray up through the jackplate. Simply put, the performance plate is like filler for a tooth cavity not allowing things to go where they should not. The performance plates' job of keeping water out of the inside of the jackplate not only increases your speed but it helps to improve your boats overall performance! A performance plate is only able to be installed when ordering your jackplate because we modify the bottom of the jackplate to facilitate the performance plate. However, you can remove the performance plate from the bottom of the jackplate if need be by simply loosening a few bolts.
