Be prepared to give him any info he may need like, altitude you use the boat at, current prop info off the hub, baseline numbers of the speeds and RPM's for the current prop, boat model and year, engine size, transmission ratio, function (skiing, barefooting, surfing, boarding, tubing, etc.), ballast use, fuel load, gear, nominal # of passengers, etc. He will need it to determine the best prop for
