Re: Mercury 60hp Bigfoot Benefits?
Forget the hub statement as that is a very common rubber hubbed prop vs the more current XHS (exchangeable hub style). The lower unit on that motor is the same as the one used on 75-90 HP motors. I happen to have a 75 HP with the standard rubber hub and there is no clutch dog rattle. You don't experience that unless you install a heavier stainless prop. You can use either. If you order an XHS style prop you need the hub to match. Order from iBoats and the hub will be listed automatically. As for performance, Johnson/Evinrude used 2:42 gearsets on their 40/50 HP motors for years and they were not specifically designed for pontoon service so your situation is merely one of propping correctly. On a very light boat, I would try a 13-1/4 x 17P. That prop should put you in the 33-35 MPH range with that engine and you should still have good hole-shot. Mount the engine so the anti-ventilation plate (the flat plate just above the prop) is at least flush with the keel to about 1-inch above it.
