Another boat question

Here's my '56 Chris-Craft Cavalier(plywood) 15' Utility. Fitted w/116HP gray Marine 6 cyl( Continental F-226) and used for slalom skiing.
Almost doubled HP from 60HP Chris 4-cyl(Hercules). 34MPH while pulling skiers. Taught you to ski 'Free of the Boat' or you'd slow the boat down too much & pull it off course slightly due to the light weight hull.
