I have an 85 S&S. The boat has a 13x13 LH prop on it currently. Everything seems ok with this pitch, lots of punch etc. but I have never had anything else to compare it to. Do you think I can get away with a 14x14 LH? We do a little tubing with the boat and some light skiing, quite a bit of cruising. Thanks for any input.

A 14X14 is for use with a 454 according to a OJ prop sizing chart, so,

Be prepared to give him any info he may need like, current prop info off the hub, the current altitude you use the boat at, 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 your application.
