trip 500 and trip 575 boats cruise at 4000 and top end??? also has any 50 ever had the bravo arneson conversion done or had arnesons....the only one I recall was the old lambo powered 50

If i had to guese i would say mid 70's......the diesel 50's had arnesons on them as well. I have a 50 that is in mint condition w/ 575's for sale.

The 575 boats run 88 to 90 mph top end.
The 525 boats run 84 to 85 mph top end.
The 500 boats run 81 to 83 mph top end.

How about 500efi Whipples at 750hp each?

The new Triple 700 w/NXT runs right at 100 mph top end, that was a fully loaded boat with ac, generator, etc.

so a 750 boat with bravos i would guess should run around high 90's to 100 mph.

That would be a nice package,cruzing in a 50 footer at those speeds.

I am doing this now on my 50' with tripple 540s. I will post when complete.

great ..... anxiously awaiting ur results...
