T-H Marine Hi-Jacker JP-4FAHD Heavy Duty Fixed Jack Plate, 4 Inch Setback, Fits Outboards up to 300 HP

The T-H Marine Hi-Jacker JP-4FAHD is a heavy duty fixed jack plate built to solve a short transom on boats rigged with a long shaft outboard. It is also a solid fixed jack plate choice for V6 outboards. This version is rated to handle outboards up to 300 hp, making it the heavy duty counterpart to T-H Marine's standard 150 hp fixed jack plate in the same 4 inch family.

The bracket is machined from a solid 3/8 inch thick aluminum extrusion for strength and long service life in a marine environment. The mounting pattern includes three engine mounting holes on top plus a bottom slot, along with two transom mounting holes, giving installers flexibility when lining up the plate to the boat and motor. The design incorporates a 3 inch designed lift combined with a full 4 inches of setback, for a total available vertical lift of 5-1/2 inches once installed.

This is an affordable way to correct a transom-to-shaft-length mismatch without replacing the outboard or the boat's transom, and it is a straightforward bolt-on upgrade for boaters running larger V6 outboards who want additional setback and lift.
