The Revolution 4 is smaller in dia. than the B1 and have more bow lift. I would try that in a 25" if your 23" M+ is way too small with the 454MAG. Otherwise a 23". What are your numbers with the mag? Remember, the B1 is actually lower in true pitch, i.e. 24" is more like a 23"-23½".

@Razor, sorry I didn't see your question in the post. numbers are as follows.

the engine is a 454 MAG mpi gen 6 from a 2007 baja.
My boat is a 22' (21' 10") mariah cuddy.

with the M+ I am turning 5050-5100rpm with a bit of throttle left and speed O said 60ish.

wasnt sure about the hole shot because I always ease it up on place. The Bravo drive seems to be a very deep set drive. when it is all the way up in trailer while in the water the prop is still submerged.

No worries.

As others here, i'm a bit puzzled about your prop slip if your drive sits deep. Have you measured where the prop shaft centerline, trimmed neutral, is perpendicular to the bottom of the boat? How is the condition of your current prop? Dings, bent blades ect. Is the boat bottom clean? No old flaking paint, deep scratches ect. Are your drive 1.5 gear or 1.65? With 1.5 your slip is somewhat high, even for a heavy boat + you say your drive is deep. I would follow Brett on this one. The M+ would be a very good choice, but so will the Rev4. Wether or not your drive is a 1.5 and your prop and bottom is in good condition, I would start with a M+ and a Rev4 in 25" to get some good baseline numbers with new clean props. And when testing, try the LaserII. If it can hook up, it'll be fast.

Brett. As you might have noticed from my earlier post's, I like the Vensura for this size and power of boat. How do you think a Vensura would work on this aplication. I've found it to fit in nicely between the M+ and LaserII. Usually faster than the M+ and sometimes as fast or faster than the LaserII, but with bite similar to the M+, better on occasion. Just a thought.

Carry on

the bottom is in good shape, no bottom paint or flaking. I am not sure if I need more stern lift to get the deep drive up or what.
