Im was running 620hp threw a Bravo xz and had ZERO problems and I did not take it easy on it. It had between 30-50 hours and had 60 hours before that on 710hp. I had it gone threw at the end of the season just to play it safe. I hear anymore than 700 and you're gonna start having problems. Also like many mentioned, weight plays a role. On a light boat like myselves, it wasnt a problem.... but if it was a 10000lbs boat I'd imagine there'd be some issues.

615HP/650TQ here with a Bravo one on my old junk 1984 27ft wellcraft excalibur. I have a spare bravo one and will be looking for more just so there is no down time come summer
Boat is kinda light for its size and i'll TRY to be easy on the throttle
I'll let you know what happens to the bravo one come summer....

My Excalibur has the VP duo prop. Not to worried about blowing that with the smoking stock motor.

Not to jack someones thread, but Im running a basicly stock 525sc on a B1 (not sure if old or new, but if i was to guess, new) in a 98 24ft Outlaw SE. Ive been two seasons with it so far, with no problems and being very easy out the hole with it. Am I just a dead hole in the water waiting to happen, or can I keep up with being easy on it for a while?

I have been running 600 plus through my b1 for 4 seasons no problems just take it easy out of the hole and watch the air time my 2 cents

Thanks Park, just what I wanted to hear! Anyone else have any opinions on this?

24ft boat ok maybe.
38 w XRs and 650hp. Let me get the bills I have paid to repair!
Forget that I dont want to add it up.

Ya, but we all know how you Okie boys run!!!

650hp on a bravo is fine......however a 28ft boat with 1 engine/bravo is certainly a load for the drive....slow onto plane and ease into your top-end speed and it should last a long time...good luck!

I want to see more post like these. Easy on the throttle and watch for the throttle when in the air..easy enough I hope
