Hello all, I am new to the forum and have a couple of questions. Currently have a 1986 Crestliner 16 ft alluminum deep v with a 20 hp Johnson tiller. Thinking of upgrading to a 50 hp tiller which is the maximum for the boat. The boat weighs in at 470 lbs before you ad in the 5 chairs, plywood, etc. It is about 77 inches wide if this matters at all. Would this motor be enough to pull kids on tubes, wakeboards, and the like? If not would a 60 hp be safe to put on this boat? Any help would be appreciated.
