Deep,

Yeah. Kinda not the same thing. Gotta love that, though.

Thanks. Brad.

Guys,

So…. Now that we’re back up to HP, I’m looking at props. I’m currently running a Bravo1 26P, and it’s not nearly enough prop. The boat leaps on plane and is just shy of the rev limiter (5250) at about 75-80% throttle. So what should I be looking for. I know props are typically a trial and error thing, but there’s a wealth of knowledge here to tap into.

I’m working on a couple of 28P options. But I’m also thinking it may not be enough. What do we know about the BravoFS props. They are available in 1” increments, making a 29P a relatively easy option. Would a 30P be too much?

Thanks. Brad.

Good job Smitty.........:ernaehrung004:......... Id run it all the way out with what you have and see where it goes before spending any money

F2,

I kinda feel like I’ve already rung it out at 5100RPM. Stock WOT is 4600-5000. I know it’s got the forged crank and rods, as I ran the numbers through Merc, but don’t want to throw a rod finding the “limits”. I think we’re already at a point we know we need more prop.

Thanks. Brad.

Guys,

Here we go. Way better video quality and starting from an idle.


What you don’t see here is that the throttle is at about 75-80% at its highest.

Thanks. Brad.

Glad you got it figured out.

I wouldn't go any bigger than a 28.

Underpsi,

Are you thinking that 28 will load the engine enough to keep the engine off the rev limiter at WOT? Or is there some other reason for the max pitch?

Thanks. Brad.

Just because the throttle lever is at 75-80% does not mean its not at 98%. Most boat's throttles are not all the way forward at actual WOT. Push it forward and see how much farther it goes and if it hits the limiter. If it does hit the limiter, then go to 28" Bravo. 2" of pitch = about 400rpms.

did I miss it,,what was the fix?

Injectors. 2 of 8 were wonky.
