Mr Gellner,
I would love to take the credit for your compliment. But I am sure you are referring to Gary Teague(aka GT Performance) who has done quite a bit of machine work for me and continues to support my performance efi engine work. Yes, he is a good guy and very knowledgable.
Kirk,
Thanks for the kudos, you gotta know I have all the respect in the world for you "East Coast Guys",,,,,,,,,,,,,,,,you guys run hard in some big water.
No doubt about it, This 28 Bullet is pretty light at 4200 lbs, but it rides nice and stable up to top speed. I always like to test a boat in flat to 1' chop to really see what the bottom is doing. This 28 bottom stays connected and really works well for those conditions.
I heard about this thread, so I thought I would check it out. You all are too kind. I will look for some pics and video.
Thanks again,
Gary Taylor

As I've said before and I will again, you are a really great guy Gary. Be careful and keep doing what you do.
You build great angines, work well with your customers and have one of if not the fastest V bottom boats ever!!

Hey,
You TuffBoat guys are on the right track, you definately don't need my help
. I will say, we are running what started as a Mercury Racing 35 lab bravo and has a little "tweeking" done to it. The gear ratio is 1.35 and the slip is 24% at wot(130+mph), The motor is turning 7000 rpm(I can hear the gasps now.
This motor likes that kind of rpm. The drive doesnt seem to mind it either. This is where the boat likes to run. It does not like a lower gear ratio, and it definately does not like 5 blades(any of them), at least not above 110 mph. So seeing how the boat likes the 1.35gr and this 35 lab, thats where I run it,,,,,,,,,safe and stable. By the way, the best we have ever done with a standard lay up and a stock x-dimension with a 525 was about 84 mph in a 28 Bullet. You Tuffboat guys are running 95. That is impressive.
Below is a link to that 130.3 article. It has a pic of the boat and motor.
To read it, just click the link and then click the left side of page where it says "Howard Bullet clocked at 130.3".

Good write up BTW. As I read the questions keep coming. Forgive me all the inquires, but your the man that just walked on the moon.
The story mentions a conservative X height, that is the whole thing right there. I'm not a motor guy, so I probably dont appreciate the hp as much as I should. But to avoid blow out at that speed especially without full surfacing the drive is awesome. I assume that you will be experiencing laminar detachment of water flow at the front of the case, which would explain the high % slip and the boats desire for alot of cup. What really scares me is the paddle wheel high pitch of a prop trying to walk the boat sideways and create blow-out. Do you have some kind of torque device on your skeg? What is the drive height? Does the boat want to crab? Are you picking up water cooling through the drive?
