Bob's Machine Shop Kick-Back Jac Plate - 45 Degree Tilt Up Jack Plate for Outboards up to 115 HP

The Bob's Machine Shop Kick-Back Jac Plate, also known as the "Stump Jumper," is a jack plate that gives outboard motors up to 115 HP a 45 degree tilt up (kick up) function. Instead of relying on chains or springs like many other jack plates, it uses Delrin rollers and bearings at the pivot points to deliver smooth, long-lasting kick-up operation. Integrated locking pins hold the plate in place so it will not kick out unexpectedly when the motor is run in reverse or while the boat is being trailered. A motor tether attachment point is built in for added safety, and the pivot points are greaseable through automotive zerk fittings for straightforward maintenance.

This jack plate is rated for outboard motors up to a maximum of 115 HP and is designed to let the motor kick up when it contacts an obstruction while moving forward at speeds up to 5 MPH; it is not designed or intended to encounter obstructions while the boat is operating in reverse. The plate measures 17.5 inches wide by 12 inches high with a 5.5 inch offset. For boaters running a clamp-on outboard, Bob's Machine Shop also offers an optional Clamp-On Motor Adapter Plate (part number 100-105001) that works with this Kick-Back Jac Plate.
