Dixon, just curious as to what your min planing speed is? Would think it'd be quite a bit lower than 18 mph with the motor hanging on the transom!
Mine went from 11-12 mph with the 300 lb V-4 on the transom up to about 20 with the 418 lb motor on a 30" setback bracket. Was able to get it back down to 12 mph with a good sternlifting 4B prop, which made a HUGE improvement in how the boat handled! With a 15.5x17 Mirage 3+ 3B prop it was very sensitive to the throttle; I could basically only plow along at about 5 mph or run 30+! It did not like to run below about 25 mph, would fall off plane very easily, and need a lot of throttle to get back on plane. With the 15x15 4B I can run virtually any speed/throttle I want, and easily get on plane with about only 40% throttle. Difference with the 4B was like night and day! Gave up about 3 mph top end but I rarely run WOT and would trade that for the improved handling any day. Denny
