Newbie question???
 

Hello fresh and green as can be so don't hate on me too much. Getting into the powerboat scene. I've been researching and chasing and trying to figure out how or what makes a big rooster tail. I'm sure there's geometry algebra X factors The sun lining up with moon just right and all that. But there has to be a simple answer and I can't seem to get I'm very new and not hip on all the different model numbers and drive names and what not. But I understand arneson drives are the rooster king and are very pricy. But isn't there a simple set up like for instance. Bravo xr drive with extension boxes and A certain prop will make a 35 or 38' boat shoot a rooster. Or different lowers will make it. I understand that extension boxes are to put the drives farther back for speed and they effect boats differently. But I feel like shooting a rooter tail should be fairly simple. I'm not talking about going 100 mph. I'm talking cruising at 50 shooting a nice tail in the air. Can someone help explain to me the dos and donts.
Thanks guys

Big hp, high x.

Big rooster tails happen with surface drives like the NXT's, SSM 6's are Arenesons. Rinning Bravo's like surface drives will break off a lot of prop blades.

In addition to the correct answers / advice that has been offered here, let me add my 2 cents. If you have a "normal" (non-high performance) boat and you want to throw a big rooster tail, all you're going to do is tear up parts. That's because in order to throw one with a normal X dimension, prop and power, you're going to have to over trim your drive. That will beat the hell out of your U-joints. Besides, all of us who legitimately throw a good sized rooster because of a correct high performance setup are going to mock the hell out of you for showing off as you destroy your out drive.

If you want a big rooster tail buy a jet boat.

What's that hose I've seen sitting behind the out drives aiming straight into the air?

Lol Def not gonna get a jet boat. Just didn't know if anyone has or knows what' setup worked for them. I'll keep asking. Maybe some one can help

Ok I understand that. And that's big money right there. So just putting extention boxes on won't raise your x???? And correct me if I'm wrong here but are the different lowers raised?? So the prop is closer to the top of the water???

Nope. In fact the further you go back, the more you have to go up. That's because as water exits your transom, it comes back up on an angle. So if you just extend outward, your prop is actually deeper in the water.

Big money or not, this is the answer to your question.

It aireates the props to help get them spinning and push the boat on plane. Takes a lot to get a big surfacing prop spinning when it is comepletely submurged. Once on plane the tube do nothing as they are above the water level.

is there a tell tale sign that the trim is too high? with some props they stay hooked up with quite a bit of trim

Yes. That would be the bow flopping around like a hooker in heat.

Three #6 boats, both Fountains trimmed all the way in to throw these tails at around 60 mph.

Buy some turn down tips, install them upside down. Full time "rooster tail" :lolhit:
