Fastest 29 Ever
 

Question? What is the fastest speed anyone has seen in a 29 late model fever? And at what point do things get really sKETCHY?

Mine runs 93 and you have to drive it. Twin 509s. Year is 95 small step.

There was a guy locally that claimed the fastest 29 ever...something around 110 I believe. Kept killing XR's, then killed a couple Konrads, finally reduced power so he could boat on a regular basis.


(I'm close with these details but know I don't have them exact, hopefully someone will fill in the exact info)

There is one on lake wylie that will do 119 with a quad rotor motor, single engine

There was a guy in Naples, Fl I talked to on OSO about a year ago that said he had a single blown CHIEF 598 and claimed his 29 did 105mph all day long. (if you read this please chime in!!)

Thats scary, I guess every time he stopped "replace the drive check the gas":eek::party-smiley-004:

I believe that was Thomas, with Crowd Pleaser.

that's the boat......just don't know all the details. Of course that boat is famous without ever starting the engine!!!!!

I rode in the Crowd Pleaser at 105....definitely had to drive through some chine walking between 85 and 90....after that it wasn't too bad.....he was going through XR's like candy and then switched to a B-max....the B Max held up better but when he did have a problem he did not have much luck with the manufacturer....I agree with Russ...the boat's other attributes were much more impressive than its speed

I would like to hear some details about that 119 mph 29. I am most curious about which drive is being used, as well as HP.
BTW...The Crowd Pleaser was fastest with the standard XR drive and 6 blade Hering. We had the prop slip down to about 3%, so we were not wasting any of the HP.(May have wasted a little grinding up those Bravo gears:eek:)

I think the last drive that Mark had was Max Machine. He tried several different ones. He actually pulled engine raised X . 6-blade herring I think . Somewhere around 1100 to 1200 HP. It handles pretty well. I was thinking around 115. Not bad for single 29

Hey Rackster dont you have a fast 29 somehow I recall someone telling me you had one that was 100+?

That was the Crowd Pleaser. It is a friend's boat. I helped him with the set up and rebuilt many drives, trying to break 100. The hull is a 2004. It has the stock 525 now,and is much more reliable.

Set up
 

Can any one tell us more about there set up for all us others with 29s so maybe we can learn from them. I have 577 bulldog and will be adding a M3sc procharger to get some more speed. Wont be a 100mph boat but it will be faster than most. Thanks

Rackster I have a 2005 hull with a -2 imco lower whats the setup on that hull to go fast? (std.length lower?) Is there any other tricks I would love to know, any help would be appreciated.

The X dimension is already pretty high on that year. I don't think that you are gaining with the -2 drive. We never tried a short drive with the big motor,but we did try a -1" Imco with the 525. It was harder to get on plane and prop slip was increased (tach was malfunctioning,so I do not have exact numbers).
We got the best top speed with a 6 blade Hering and a standard Bravo XR, however the boat rode and handled better with a Maximus. The Maximus prop provides stern lift and frees the hull up (even the women on the boat commented on how much better the ride was).
The 29 has a lot of good qualities, but there are some major challenges with trying to make it run 100+. You are pretty much stuck with a Bravo style drive (unless you re engineer the engine bay) because there is not enough room to add a transmission. These hulls are fairly heavy for a single engine application, and put a lot of stress on the drive. I feel that horsepower(torque) and weight are what determines drive life. When you increase HP on a hull that is already heavy, it is hard to maintain reliability,but we still try:cool:

I have tried many different setups on my 05/ 29 hull. I had a bravo xr upper and a imco -2 lower with a 2" spacer which should bring the Xdim. back to factory spec. Interestingly enough it ran faster with a std. length bravo lower I think the shape of the xr works better because the "nose cone" on the imco tends to dig with positive trim.I also have tried a hydromotive P-5X/5 blade and it stern lifted so bad it would stuff the bow.These are just of the few setups i have tried.No setup seems to work very well (lots of prop slip) and yes you are correct this hull is extremely heavy 5800lbs dry. I am open to ANY suggestions or advice anyone can give is much appreciated.
