well chris i think you are going to be real happy with the 540 with the lower boost you are going to have a very dependable motor. on the other hand eric and i went to the lake while ago hung over from my birthday party last night (good times and great friends thanks!!) but anyway we broke the 100mph mark finely we ran a 32 six blade herring and the boat loved it very driveable and pulled the motor 5800. i wish i had a video to post this prop carried the whole boat so high you could feel the boat dancing on the rear of the pad it felt like you were driving a bass boat. and last of all i would like to thank eric of eb marine for all the help he has given me over the last year with the boat.

Congrats Jerry!

It is a neat feeling isnt it

I have no desire to go any faster in my boat. Just an easier time getting over 100 consistantly, and being able to swing a bigger prop so as to increase my 3k - 4k cruise speed.

Chris

P.S. I love my boat!

Which brings up a good question... Who has over 100 mph Nordic V-bottoms? and what are the speeds?

Jerry - 100+ mph - Nordic Heat Closed bow - 540 with 3.3 whipple.
Nate - 102+ mph - Nordic Heat Closed bow - 598 with 3.3 whipple.
Chris - 100+ mph - Nordic Heat Open bow - 502 with 4.0 whipple

Guy in WA had a Rage going 114.7 with a 572 twin turbo motor..he later put that motor in a Thor...and now goes 142 mph.. The Rage was very unstable at speed

The guy with the Yellow Nordic Heat with the 598 quad rotor motor does 108 mph+ This is with a Bmax drive, a 1" shortie, 1.35 gears, and a merc lab 30 spun to over 7000 rpm.

If you can add more... please do

Chris

chris with that prop at 3200 we were running 60 and at 4000 we were running 80 talk about cruising speed what a good feeling.

Jerry,

32 pitch Hering prop
1.5 gear ratio

3200rpm = 60mph = 7% slip
4000rpm = 80mph = 1% slip
5800rpm = 100mph = 15% slip

Chris

thats what we came up with also but 12% on top i dont see the drive lasting long with it.

Jerry... That is a definate drive breaking combo you have there.

Chris
