Looks like there were 23 boats that showed up to race in Ft. Myers on Sunday.

I think the guys login name was omcdeal. It was pretty ballsy thread. To bad it got axed it would have been a good one!

Hey Troutly,
What challenge?

the teardown to see if the motor was leagal challenge--i would rather see the motors pulled and dynoed---i have heard alot of hp500 motors--those sound a little different---

Hey JFM311,
Thanks for the info I agree. Send them to CRE!

We would love to post movies of the races but the rights belong to SBI and without their permission we can not post.

Well then, get on the horn and get it done. :D

Troutly,
You are right it was a very sporting challenge but who was gonna be the mediator? Someone that is impartial to both sides of the coin. I guess money talks and BULL**** walks.:cool: Mr. Threadstarter did not want to play.

Here is an Excerpt from the SBI Rule book ? Now 2 of these Engines with parameters Specked out below are going to push an 11-12 Meter Vee hull @100 MPH LMAO Now that my friend requires a giant leap of Imagination Using only Line 11 of 13.8.2 ! A casual glance at the Boats prop size Verses the top Speed Should give a “Hint” oops better remark the props.

MANUFACTURERS CLASS I

:p

How many people here have been told by a few SBI F-2 racers (within the last 12-18 months & don't mention names) that they needed to "bump up their engines" to even try and stay close to the "cheaters" in F-2? I know quite a few and no it is not "hear say." It came from the horses mouths.

I even know of a local 'L' class boat that got walked by one of the F-2 boats and this "L" class boat has 750hp a side!
