Valero YT Setup

Randy I just got an 87 Valero YT with a 150xr2 mercury with a LWP 2to1 foot and a laser2 25p. I thought I was turning to high off rpms. so I put on a 30p chopper and got 60mph at 6000rpms with a GPS. Iíve been told I could not turn a 30p. My tach may be off. What prop should I run to get top end? And what speed will I see if I turn around 6000 to 6500 rpm? What would be the best motor to put on this boat?  I am going to have the tach checked out.

Thanks
Jim

 

Check out the tach, but drop the motor down a bit. You may pick up some prop efficiency and gain some. You can figure about 67-68 mph for that combo.
