80 MPH in a 292 Fastech with just 500 HP
292 Fastech
no cabin just 5000 lbs single 500 EFI 28 LH lab finished Bravo 1 @ 5900 RPM (modified rev limiter) 80 MPG GPS http://www.youtube.com/watch?v=No-KwO56Ai8 |
That's moving for a single eng 29'er, don't think you could do that here at LOTO, the bath tub on the weekends would chew you up, nice ride though.

Seems like your prop is slipping quite a bit. 5900rpm with a 28 should put you in the upper80s
Have you tried different props? |
Not sure if that video has me convinced....
|
No Way IMO
|
I think it's possible.
Mine weighs in around 7500 lbs and with twin 320HP it hits 70-71 mph. Knock off 2500 lbs and an extra outdrive, 80 mph with 500HP should be doable. At the rpm they are running it is maybe a little more than 500HP. |
500 efi stickers. Prob need closer to 600 hp and no fuel etc.

This boat is extreme lightwight
have a look at pictures and see both steps above water line compared to a stock 292 The X Dimension is pretty high and it takes a moment to get on plane but from there it goes like hell You are welcome to take a ride - just jump on next plane overseas I drove many performance boats , but nothing in similar size ever came close to the MPH output from just 470 HP at propshaft (500 EFI) We have a 271 Fastech with a 525 EFI here This one is doing 70 MPH all day and 72 in perfect condition Its also using the same prop - 28 LH lab finished maximus but its not exceeding 5300 RPM The video ride was shot at sea level in the South Netherlands |

The "Cabin"
The boat gained 500 RPM by removing the spacer , that the previous ownner used for what reason ever |
I am not doubting you run 80 , I was just saying your rpm is way too high, your running over 20% slip ..
Get that slip down and you may run even faster! |

:drink:I still think it is possible. pokerrunboats, how about some gps shots while running?
Also, back in the day didn't the single engine 292 just like this win an offshore championship for the year in its class? Can't remember the year, but remember reading about it somewhere. |
Might be possible the F-class formula boats are fast. These F-1 boats are not layed up production 292's so we aren't just subtracting cabin/rigging weight...it is much like the 382s(kevlar hulls) which I am pretty sure were hovering around 90 with 500s and 82mph out of a set of 496ho's! Plus all the factory racing boats (both 292's and 382) all have way different CG's and dash positions from production boats. See below on information on the 382 f-2 for comparison.
"For a brief moment it looked like F2 was going 496HO in 2005, so the dealer suggested this package. I never planned to race the boat and went ahead with the 496HO/XZ package. The result was outstanding and affordable for pleasure use (80+MPH on black Mercury power). With the former 470hp package the same boat will run 84+MPH and with 525s (or Whipples on the 496HOs) it will run 94+MPH. My only problem is that I didn't have time to use the boat (30 hours in four months) due to my business travel schedule... reluctantly I put it up for sale and it went quickly" |
Just an observation, but in the video it sounds like it is not opened up until the 13 second mark, so likely not topped out at 80 mph going by the camera.
Need more fly-by video! :boat: |
This is an original F1 boat and it runs 80+ with a HP 500 ..i am 100% sure !
