Stupid Prop Question
 

Just cus i'ma spaz i wanted todouble check standard bravo rotation is righthand right??? Seeing as my new engein is on its way I will be needing a different prop. I had a 19p Mirage+ with 1.32 gears on an alpha drive witha 330HP BBC.

I now will have a 550hp BBC with a 1.5 bravo. I think the 19p is gonna be WAY to small I figure i will need a about 26p bravo1. I figure that is a good starting point. What is the pitch difference between a Hydro and Bravo. I was also thinking i might try one of those older merc 5 blades. Were they decent or crap. I am looking for a fast cruise not all out speed.

With the old drive engine setup the boat felt much better with the mirage+ than the plain old mirage.

But my stupid question is i need to buy a right hand rotation prop.

Actuallly, with a Bravo drive you can turn it either way. Preferred is right hand. I expect you will probably want something smaller than the 26 but that is just a guess. Remember you will probably have a difference in RPMs to consider as well as the gear and horsepower changes. A Hydromotive prop will seem to have more pirch compared to a Bravo because of the way each is measured. A 24 Bravo should run in the vicinity of 70 depending on RPM and slip. Keep us posted.

My brother laster is right you can spin it either way.....26 is way to small though bro....On the factory boats were running 28-33 pitch props.....Now then have I gotta surprise for you stud! I happen to have something very unique that i want you to try out.....Is it a big shaft bravo or small shaft bravo?????? Call me 856 498-9606.......Don't call until thursday though as I am about to walk that isle brother.......

good luck with the wedding!!!!

are you going to be at the NYC race???

puder,

What kind of rpms do you want to run ? or what kind of rpms will the motor run ? You have a single engine application correct ?! What length boat ?

I have a single 550HP Baja, 28'. I run a Mirage Plus 25, @5000rpms. I ran a Bravo 1 24 @ the same rpms. You may want to get your hands on a Bravo 1 26 and run it(try it before you buy it). See what it does for you. I run the Mirage Plus because speed was a bigger concern. The Bravo 1 's will defintely give a better "cruise" and hole shot.

I think a twin application could use larger pitch props (28-33).

my WOT should be about 5300.

but my cruise RPM is 4500-4700. That is were the VE numbers are the best BUT 4700 is kind of high.

the boat is a 26' scarab excel single 550hp 454.
