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.

Thats pretty good

Should be able to compete with most brands out there, even
the 29 (26) Fountain

Keep up the good work with Formula in Europe

Seems like your prop is slipping quite a bit. 5900rpm with a 28 should put you in the upper80s


Have you tried different props?

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.

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
