expected speed increase with 150-200 hp
#1
I have one more question- I am looking for an average mph increase that I can expect to see with an additional 200 or so hp. I am comparing a merc 600 sc motor and a KE 675 motor that on the dyno was 700 plus hp. Assuming all other factors are equal. THANKS

Thunder- keep weather conditions in mind . I have noticed 2-3 mph depending on heat and humidity. Also tides and wind. Are the KE's intercooled? If not, you may not be hitting the dyno'd hp while running outside in the SE's heat. Saltwater a little faster than fresh. My boat runs the same speed as one with 575's when it's hot outside.
Hope you hit that bumble bee -- !00

My experience has shown almost a wall at about 92-95mph
in most V bottoms. Getting from 95 to 100 often requires
more than just increases in HP, drag becomes your biggest
problem, ie X dimension ect. Getting from 100 to 105 all
things become exponential. Go for it but be ready for some
real disappointments.
