Prop suggestion?
 

I'm currently running a stock Bravo 1 4 blade 28p prop. Boat is a velocity 280 with a 1.5 ratio bravo 1 outdrive. I'm currently getting 5200 rpm WOT and 73 mph with 2 ppl and 3/4 tank fuel. The engine is a fresh 496 stroker, 590hp. I'm considering stepping down to a 26p to utilize my rpm as I keep making power to 5600 rpm. Would a 26p bravo 4 blade be recommended? Or is there Better prop for this boat to get more top speed out of it? I'd like to find a good base prop and possibly have it labbed from there.

Most likely would be best to have your current prop labbed.
Your prop slip is on the high side at about 18% already so talk to BBlades about your options.

I guess I should mention that the 591 dyno number was not in marine dress.

thats definitly my plan for the offseason. It's currently my only prop so I'd like to get a spare anyways, and figure a 26p might be a good choice? The 28p has the diffuser ring cut off, but gets on a plane effortlessly, and will even plane with 6-7 ppl on board and 3/4+ tank for fuel , definitly working, but it gets up

I'd start with a 26 Bravo. The net 2" reduction in pitch will get a higher rpm more reliably than labbing a prop. I'm not against labbing but I'd start with a different prop in this case.

Being as it's a stroker and loads of torque down low, I'm curious if there's a different drop/# of blades I should try to give up some down low for top end

I agree. I think the 26 Bravo would be a good prop.

Where are you located? Maybe you can borrow one to try.

im up in Vancouver, BC. Unfortunately, there isn't much of a performance boating community up here

Where in Vancouver I'm on Vancouver island with a 36' cig just working on some props from Ontario not much out here in B.C for sure.

My initial thought is to Lab the 28 with a efficient recipe.
However, a dyno sheet would clarify the decision.
Let us know if we can help.
