Hello, I have a 1999 seafarer 228 with a 225 ox 66 2stroke mounted in the second hole down in the upper bracket. It has a 15 1/4 x 17" stainless 3 bladed prop. It runs very well and will top out at 41 mph with a full tank(92 gallons)10 gallons of fresh water,and 2 people on board.I was wondering...
