Location: minocqua, wi. | i don't understand ... turning rpm's isn't the goal, if it is then put on a high-five and spin the motor. i'd rather have plane at 26mph and 51.1 cutting and moving water with the rev 4 at 5200.
when you cup and rake water you will lose rpm's, you may see an increase in rpm's on a 3 blade with some more speed, but you'll suffer that flat ride and launch you get from the rev-4
51.1 with a 150 and 26mph on plane with that boat is very, very good performance.
if you want more you will have to get a 175hp outboard or buy another boat with a 200-250hp motor. |
