115 hp e-tech enough for an 18' SF?

[Bushwacker]

In a word, YES! (Unless you want to run 50 mph!) Skip & Carla's 19'Bowrider runs 39 mph with a 115 E-Tec with an aluminum prop. A stainless prop would add another 2-3 mph. Check out Fr. Frank's excellent reply to Windrider's engine size question in the performance section. But recognize that the 18 is even more sensitive to engine weight than the 20!
