rooster tail
 

okay i know that i am the "little guy" but i need to know what makes a boat rooster tail cause some day i need that . heres the thing was running the boat on the lake and came across a 30 to 33 foot something was not a cig ,fountain or anything common but had twin engines and yes he walked me but this was not a 100 mph boat he was low seventies tops , but had a giant rooster tail . i understand that trim is what makes the rooster tail but i can trim all i want and never get a rooster tail . is it a twin engine thing or is it a hull thing also i understand that certain props ride higher in the water which i would think would cause a rooster tail . lastly in the future i need a 35 lightning with twin 600's or 525's would this boat"rooster" .

p.s. yes i am a dork

Hit your trailer button after you max out your trim that will give you a rooster tail ..but it puts a strain on the u-joints..

running a imco -2'' ''shorty'' drive will give you the same effect..

surface drives will have a roostertail as will jet drives and boats that run the prop close to the surface, there are several different things that can cause that.
depending on the set-up of the fountain, it could.

by using -2 shorty drive is there any performance gain on my boat other than a rooster tail , also does help or hurt the overall performance of the boat just looking for pros and cons .

that would depend how fountain set up your current x dinention..you may want to go to the fountain forum and ask questions their..in most cases you will pick up 2-5 mph,,you may need to go to a bigger pitch prop also when you change to a -2 lower..

Surface drives throw major roosters

okay thanks all for the info

no way to get the rooster tail your wanting unless you do a full stagger set up and 6's on a fountain. I've got full stagger and xr's and get a baby tail but my buddy's 700/6 set up is unreal! good luck.

A 42 PR throws a SICK tail even with the 525's. I'm pretty sure your boat was my poker run boat for the 06 season.

remove bravo, install Arneson


OK Rik, send my free drives, drop boxes and accessories.

Me to Rik, or how about buy one, get one FREE. I might be able to afford that. I want Arneson surface drives on my flat bottom Cigarette. Time for you to post that picture of that rooster!:drink:

Rooster tails aren't necessarily good. I could be wrong, but throwing a rooster tails is essentially a loss of torque. I agree with these guys though. Get a shorty, increasing your x dimension and it will raise the prop of the water. Increase the pitch for reduced water tension and you gots yourself a rooster tail.

O yea? Thanks for the great boat!
It use to throw a pretty good one till i saw my buddies #6 do it.
I upgraded to SCX and they come with a cavitation plate that seems to reduce it now for some reason....or maybe its the Herings...or maybe its just me! ;)

Yes, thats a fun boat. Have you seen the pic of the Fountain speed record boat when they throttle up with the 1550 sterlings?? That tail couldve soaked dowtown Washington NC LOL

I know....Unreal the water coming out! Seems like that isnt efficient but if anyone knows how to make a Fountain scream its Reggie and Brian.

If you're on FB you have to look at pics I have posted of blow up dolls strapped into the back seats of your boat during the KW poker run

i would also think that a rooster tail is a loss of torque is there truth to that ! anyway its stupid i just think it looks cool lol . is it just me or can you buy a lot of boat for 60 to 70 k right now i would love to have a 35 , i just have no where to put it (sad) . can you put a trs lower on a bravo 1 or i guess what has a -2 lower that fits on a bravo 1 just wondering and keeping my eyes peeled .

does anyone know what prop slip #'s are when you have a giant rooster tail

Will these do?

Here's a Cigarette fix you.

You know what they say, double the price and then take half off.

OK, getting back to the OP's question, a big rooster tail might - and might not - be a bad thing. You can generally throw a pretty big rooster just by over trimming a boat. That would be very inefficient - and tough on the u-joints too.

You can also throw a big rooster tail in a boat where the prop shaft is closer to the surface of the water. (That's that "x-dimension" thing they're talking about.) Generally speaking, raising the propshaft height relative to the planing bottom reduces drag on the gearcase and thus increases speed. You also get a free rooster tail. In my experience though, unless your drive is mounted really low or you're going over about 75 MPH, raising the drive up doesn't do much.

How do I know all this? I run an outboard and have for years. I also run mine with a jack plate - which allows me to alter my x-dimension at will. I currently run my Diamond Marine modified Mercury 200 well up the jack plate / transom. My hole shot stinks, but top end is quite nice and a huge rooster - even at zero trim - comes with it for free.

Hope that helps.

My slip#'s are 14% give or take w/ KAAMA drives. (Rick wont send me a set of his for free either. :)

Just a thoughtg before you realize you DONT want a huge roost after you find out the cost of one. Put the $$$$ into your motor and set up and wax the S#&T out of the 30 footer and he will be wanting what you have.
Do you want to finish first, or look like you could have???:drink:

I told you, here is is all you will need :D

4% when there dialed in BIG Daddy :drink:

I've got a 35 at the shop right now with a pair of 1050's and shorty XR's with six blades. It throws a roost and drives at the same time.. :lolhit: We'll see how it does with SCX's.

Here's a 36 supercat with #6's

Now I need a SHAM WOW to wipe the DRooooL from my laptop!!!
They cost more than I have into my boat, ,,,,,,,,,, Wish I had a better boat. HAHAHAHAHA It is a Skate Nation!:drink:

Look a little closer at the photo. Those are for a "Model Boat" :D

Pretty tough to tell with just a glance, nice one! I would love to have a pair of arn's for sure. Think I will wait till I get a new boat. I have mine for sale now think I need somthing a bit bigger for Lake Superior than a 30 footer. Might go with a vee but it will have to be nice, really nice. I can only imagine that the new technology offerd by you is the way to go, as the old Kaama I run seems to do quite well and is old and heavy. Had my first scare last weekend Lost a fuel pump in a hard turn @wot. a little like an 8000 lb pinball! Made it out fine and repaired it to go on sunday agian. Oh yea it was a huge rooster when the other sponson planted.

I raised my drive over 2", gained 10 MPH

Plate was below the boat, and plowing through the water, now plate does not touch at speed.

HUGE improvement, no downside, great rooster tail as well!

22' Velocity 600hp 406 Alpha drive with Hydro nosecone 4.5" below pad 26p +1"(27p) Hydro Quad IV. Will throw a heck of a tail but at speed will actually cost a few mph when trimmed that high. This was running only 35-40mph getting going and I trimmed it up some for a pic. It actually goes a bit higher but at low speed loses grip pretty bad.

Is the roost only @ high speed? I'm considering raising my drive from 8.5" up to 5.5" but don't want any roost @ slower speeds. Mostly wakeboard, ski, tube ect between 20-35 & a roost wouldn't be good.

You Should Only Trim Up Until You Stop Gaining Speed Then Thats It. No Point Over Trimming, Just Waisting Horsepower. In All Reality Your Roost Shouldn't Be Over The Back Of Your Boat.

Raising your prop that much will make the surface of your wake much more turbulent for wake boarding and knee boarding. You should be able to trim down enough to avoid a roost, but it will be more turbulent. It also will likely be faster with the right prop.

roost?:drink:

Only have a tail when I trim up. I can blow the prop out and toss a hell of a tail at lower speeds but its all on purpose and to show off. Normally you won't see it till I'm up and running pretty fast (70mph+) and even then its not over ~2FT. Any higher is a waste.

Car Biz- Got to love a surface drive :)

Thos surface drives DO throw insane roosters, especially if you have a PILE of ponies in front of them, I often see "MY Way" and "Aquamania" blasting downt the river and the rooster coming off both of those things looks like Niagara Falls!

Money455, I have a Fountain 35 with the staggered 525's. If I put my drives in from normal the boat will throw a 5-10' rooster. When you see it (from a Fountain at least) it is probably just showing off. Trimmed out the boat is doing about 60-64 at 3400 and no rooster - bring the drives in to 1-2 and the speed drops at least 5 mph with a big rooster.
I have the XR drives with the 2" sportmaster shorties and 5 blade Maximus props turning inward.

My boat runs fastest with a tad bit of roost with the raised x. Most boats loose speed with bravo's when you have roost. Every boat is different..........
