We are looking at new 18 ft I/O bowriders.<br />One weighs 1950lbs. and the other 2600lbs.<br />Our family weighs 600Lbs.<br />Add another 600lbs. for freinds.<br />Will the 3.0 give us enough power to ski or is it worth the extra $2000 to get the 4.3<br />Will the 3.0 give us enough power to ski with just one famly in the boat.<br />The manufaturer of the heavier boat says that it is all in the hull design.I Can't imagine that one company really has a better design. They all claim to have the best!!!
