[QUOTE="airshot, post: 499439, member: 1183"] Your motor could be raised a little from the pic, but wont make a big difference. You need rpm to make HP so a tach will let you know how your rpm measures up. Your 4 stroke is geavier and wont have quite the snap a 2 stroke has. I had a 14 Starcraft, slightly newer with a 9.9 evinrude and could get sbout 15 mph, added the carb upgrade to a 15 HP and could get 20 mph plus. A tail fin slowed mine down, so I made my own fin, smaller and made from .030 SS , only slightly wider than the cav plate but about 3" longer out back of the cav plate, then added a slight angle down about an inch back...this worked perfect !!! Now I could get 22-24 mph with just me in it. My two stroke only weighed 64 lbs, had fuel tank on one side and battery/ electronics on other side between back and middle bench seat. While your 4 stroke might use a little less fuel, you wont have the speed a two stroke has....really think you might want to go to a 18-20 hp....in my younger days we had a 14' mirro craft, with a 18 hp evinrude (1964). We could pull up a skier with that. (Skinny one)..... [/QUOTE]
