I have a 2000 Pathfinder 15T. Just installed a Honda BF50A. I have a Honda 3 blade stainless prop 11 inches dia. and 13 pitch. I noticed that my anti cavitation plate measured 2 inch above my tunnel. It's slow to get on plane even with tabs fully down. With WOT the anti-cavitation plate is above the water line. The motor is at it's lowest setting. Is there a product to lower the required 2 inches. I know a jack-plate is designed to raise the motor, but what is available to lower a motor?
