Im having some 650hp NA's built for my 37 with Bravo's and was wondering what kind of speed to expect on this setup, any of you guy have a similar package?

you should be in the low 90's. We had a 37 with merc 575's( arizona speed and marine comps and smaller pully's about 650 horse) and it ran 93

congrats..love your boat.. Who's doing the motor rebuild for ya.

Thanks, Smith Power in Joplin, everything he does is done right. hopefully get it painted this year as well, been a fun build so far.

Make sure they build them so you can slap on some blowers!!
O YEA

JUST SAW SMITH AS BUILDER great.
who is building them and mid 90s, I was in there 1st race boat we were running a buck with that or a lil more power and it was 27degrees staggered set up, nothing like jumping a wake at 100 of a 250ft long ferry boat it was sweet.

We have one here that run's 95 with that kind of power. he has a gen and A/C in it also

have any idea what props he is spinning?

what drive ratio and prop

I have no idea.
