[h=2]150 HP Evinrude not reaching RPM´S[/h]
Hi Everyone, Im new guy to this forum!
I just bought a Champion 18´6 bass boat With a 1993 150 HP Evinrude Ocean Runner (20" gear case) seated on a 6" jack plate with a 14-1/4 x 23 Alumunium propeller.
The compression test result was 115-120 lb on each cylinder.
The hole shot is excellent ,but the top speed is just 45-47 MPH and just reach 4700 RPm´s
Where should I Start to make changes to reach 5400-5500RPMS and increase my MPH??
I did Rise the motor with the jack plate 2" but I did not perceived substantial changes
.
Thanks in advance.
