I plan to buy a new 18' Bayliner with outboard to be used for cruising and water skiing (about 50/50). Should I go with the 125 hp for the power needed for water skiing? Or will a 90 hp be enough and save gas? I appreciate any help you can provide. This forum is really great. I feel much more confident about buying a boat with the information I have gathered here.<br /><br />Steve
