15 ft fibreglass runabout. 1993 90hp tohatsu. 13 3/4 x 17pitch hustler prop. cavitation plate about 15-20mm above the bottom of the hull. it turns 5200rpm at full throttle. not sure of the mph. I believe its in the range it should be. I am not concerned about top speed but interested in a bit more hole shot and wondering if going down to a 15 pitch is the way to go?
