Summary for the User

The JPZ-6-DP is an excellent choice if you are looking for a set-it-and-forget-it solution to optimize your boat's "sweet spot" for speed and fuel economy.

Installation Tip: When installing, ensure you use a marine-grade sealant on the transom bolts to prevent water intrusion. Since this is a manual plate, it's best to adjust it in small increments (1/4 inch at a time) while testing your water pressure and GPS speed to find your ideal height.
