I have a 92 Ranger 482V with a 92 Fast Strike 150, jackplate, 24P raker. Recently trying to get more top end with no luck.
(Weight has not changed for any of the tests. One tank empty one tank about 3/4, passengers equalling 350. Lbs, equipment about 100 lbs.)
Test #1 (how the boat was when I bought it)
Jackplate all the way down, prop shaft 4" below pad, 52mph @wot of 4800rpm
Test #2 jackplate raised to 3 1/4" below pad, 50mph @wot of 5000rpm.
Now I'm confused I raised my rpm by 200 but lost 2 mph. I'm going in the wrong direction. The boat gets on pad like a rocket ship then just slowly and I mean slowly gains speed. Like a middle to 30mph. Shoots a rooster tail of I trim up like always. What am I doing wrong? What should I try next? My max rpm is 5500 so I'm low 500 help me out here.
