There may be a difference in gear ratios like there was between Bushwacker’s 150 ETEC and my 150 HO ETEC, both on 20’ Seafaris. I dont remember the details but his liked the Cyclone better than mine, so he bought it. I had better low speed control at 17 mph and achieved the desired WOT RPM with a 17p High Five.
