1988 13' Super Sport
2000 35hp 3cyl Johnson w/trim tilt & oil injection Mounted 2nd hole....
Rated RPM= 5200-5800
Whale Tail installed

New to me boat W/no history

Took it out today and it only did 26mph GPS @ 6000 RPM (Light load just me and 2gal of gas) 14p 4-Blade Aluminum prop (Engine gear ratio 2.15:1)
I assume that the whale Tail is loosing a few MPH but if the tach is correct it does not make much sense.
It jumps on plane in 2 sec and runs very smooth..
There is tons of info available for the 2cyl engines but nothing on the 3cyl.... It is geared like the E-tec and has tons of power..
Any ideas on a prop to get closer to 32-35mph?
My thinking tells me that a 16 ish pitch would get me close but that just seems crazy for a 13'

Video of it running https://drive.google.com/open?id=0B8w...zB2ZHl2alU
Sorry I can't figure out how to insert it into the post.. It doesn't list what format will work....

Thanks...
