It's rare when a product works as advertised AND bolts-on like it's supposed to. This is not a sponsored video we are just passing along the good vibes about an excellent product from Place Diverter and Controls. In episode 170 of Mike Finnegan's Garage we swapped nozzles on the back of our Berkeley jet drive, which powers our 1976 Rogers Bonneville TR and GAINED three mph of top end speed. Our butt-dyno also says this mod also increased the boat's holeshot. We also adjusted the angle of the nozzle and gained another two mph of top end speed. The nozzle swap took less than twenty minutes to complete and required no drilling, no wiring, and no grinding. It was just that easy!
