How fast 1979 25.5 Formula Liberator
 

1979 Formula 255 Liberator. Twin 350/260HP Carbs W/Alpha Drives.

Does anyone remember how fast these boats ran with twin stock 260 alphas with good SS props.

I'm thinking 55 MPH tops with no gear and light fuel.

No tie bars on the out drives!

With twin 300hp maybe 60 ish before it starts walking all over.

What do you guys think?

I think you are about right with the 55 mph.

55to60 gps would not suprise me at all, I know it should run with my searay and thats where thats at.Always liked the looks of that boat...

as a comparison, 77 250 nova with twin 302/188s 47.9 gps half fuel 4people.

I have 1975 Formula F26 with late model 350-260 & BIII spinning 22 p props. Smokin' 40 mph !

DonziDog,,,,Ya need a nuter mtr....OR I'm not as good as I once was but I'm good once as I always was...

Did you ever get a speed reading. I am getting into a 79 255 and would like to know.

I would say easily 60 maybe 62 if the engines are running good. Used to have a 26 Monza copy with twin 260s radared at 63 back in the day with cleavers.

255 Liberator is big ,tall , heavy beast with some built in hook in the hull,
it is more of a cruiser with a somewhat sporty look,
I would be surprised if it ran faster than 55mph with twin 350s stock.
