few questions for the krypt guys
got my 27 w a 500efi (stock) and a 28 Bravo 1 hittn just under 4900 rpms @ 73mph (gps on phone) in the water this weekend and have a few questions. according to powerboat magazine this exact boat was tested in Sept 2000 and ran lil over 80 w Teague driving and a 28 pitch bravo. I'm trying to get a build sheet from Kirk.
Anyone have Kirk's number ?
Are the fuel tanks a part of the boat (like skater's) or are they seperate (aluminum) ?
Fuel tank capacity ?
X dimension ?
thanks and any other input would be appreciated as well

Should be somewhere around 100 gal fuel cap.
I know that boats are "supposed" to be fastest at neutral trim, but try trimming it up more. Mine gets faster the higher I trim it, to the point that I get nervous for the U joints and stop bringing it up.
I am set up at around 3" below the pad with an ITS box and no notch, and would like to bring it up higher another inch or so.

Race boats and pleasure boats were set up different from what Kirk told me. (Please be kind I am remembering conversations from 7-8 years ago.)
My boat the fuel tank was directly under the rear seat. I had 90-100 gallons if I remember correctly.
X-dimensions were all over the place. Mine was the first one he built with an extension box. I first had a standard length then swapped to a 2" shorty.
The boat liked to run 1-2 clicks above neutral trim and I used to run the tabs neutral and slightly drag them in an oncoming sea. The boat runs best flat.
I have a 27" or 28" labbed something lying around. You are more than welcome to try it if you like.

I would LOVE to try that 28 labbed if you have it lying around!
The kryptonites do ride flat. Stock props work best. If you lab it take the stern lift out and cut the diffuser off. I also leave the tabs dragging a bit. I cruise 1 click below neutral and 1 click above neutral if I'm getting on it. Some people love the ride, some people hate it. Its very unconventional for a 27 footer to run flat. Most of them hang out.

When I go through the garage I will post what it is and if anyone wants to try it, they can have it.
If they like it and want to keep it (or bang it up real good), make a reasonable offer.
Just cover shipping.

Mine is running great this season. Just over 12 hours on this motor and pulls to 6000rpm with 4 people and a full tank of fuel on board as long as I trim it up to get the bow out of the water some. Mid to high 90's fully loaded is nothing to complain about.
