More than 65 MPH with a Bravo III?
 

What is the top speed of your boat that has a single Bravo III on it? Is anyone going more than 70 MPH? I have been told that Bravo III's are not the way to go for speeds over 65 MPH. I have asked the forum about changing to a B1 and everyone is trying to talk me out of it....

I have a 23' Chaparral 2335 with a 502 EFI warmed to 500 HP by Teague with a Bravo III and labbed 26 pitch (4x3 Merc) props. The boat weights less than 4900 pounds fully loaded and has a 22 degree dead-rise. Currently is runs 5200 RPM for a top speed of 65 MPH

I know of another boat like mine with a Bravo 1 and slightly less HP that is running 71 on GPS...

Anyone going 70 MPH with a single Bravo 3 out drive?

Chris Reindle owns the Early Detection BatBoat that can do well over that with a Bravo 3. The same boat if faster with a Bravo1, but the prop torque makes it lean and affects the handling considerably. good luck!

Stock B3's are very efficient up to about 60-65mph but after that they start holding you back due to drag. Do a search on here because there are quite a few threads on here discussing it in detail.

lots of info on this thread...

Phragle? Cruel joke? Or a mistake? You gave me a link to "this" thread...........!

I appreciate your help, can please forward the link you were trying to show me?

Sorry didnt realize the other thread was yours too.

You know......I changed my mind. It's not my money, go buy a B1 and try it. There's not enough data out there to verify what will happen and you obviously want to try this. JUST DO IT, and report back to us what the results are (lack of posting results are probably why you can't find the answers your looking for).

I have driven that boat into the high 80's, its pretty fast. The B3 hits the brakes right around there, power needed to go any faster grows exponentially and things start to break. The batboats are about two feet narrower and fifteen hundred pounds lighter so its probably not the best example. Safe to say its not a great performer, your better off with a B1 drive if you looking to go faster then say 70.

A 3 x 3 lab finished prop set would probably be faster if you stay BIII. Who is trying to talk you out of a Bravo I? I see no major downside to trying a Bravo I on your boat, which I am very familiar with. If the big end is where your focus is then what little you will give up on time to plane, cruise, and docking should be worth it if indeed the gear case/multiple props of the BIII are holding you back.

I thought the Green Bat Boat was running a Blackhawk drive..........
