Manual Jack Plates for 225–400 Horsepower Engines

Even powerful boats can have trouble getting out of the hole, which is why Vance Manufacturing offers boat jack plates for 400 max horsepower engines. Installing our manual jack plates for 225–400 horsepower engines also lets you use a long-shaft engine with a short-shaft transom. These plates come pre-drilled. We have a calculator to help you find the right hardware kit to mount our jack plates to your boat.

These 4- and 6-inch jack plates for powerful engines have an adjustable vertical lift and higher mounting points. This gives you 5.5 or 7.5 inches of total vertical lift, depending on the model you choose. If you have an unusual mount, you can drill through the aluminum of our 225–400 hp outboard engine lift plates to get a custom fit. However, we cannot accept returns on modified plates.
