Works great for a 1436 Jon Boat. You can raise or lower and adjust it by uninstalling it and re-bolting it. After installing, I realized that I could go up one more inch. Just drill out the marked holes on the mini-jacker and re-bolt to transom. The wood has no water protection so a couple of coats of outdoor polyurethane on each side of the wood should work fine. Also used clear silicon around the bolts and where the mini-jacker makes contact with the transom. Uses 6 bolts, not included. Very sturdy for a 85 lb 9.9 hp. Now the ventilation / cavitation plate is 1 inch above the keel.
