I'm running a 1990 Ranger 374V with no jackplate and a 150hp Johnson Fastrike with a 23Raker with cup added by Mark Croxton, my numbers today were 5600rpms and 57 mph a buddy was out and video taped my boat running and sent it to me and it looks like my roster tail is about 2 feet over my cowl give or take . Should I try to bring this down or try a different prop?? or just leave it as is ???
