Vulture 20'

[bayouboy2]

Need help in setting my 20' vulture it only has a stock 150 merc. But need hepl for setback motor height etc thanks

[motorheadbishop]

10-12inches of set-back is nice
Helps fly the big bird.
Depending on prop and lower unit.
Start with the prop shaft even with the pad. (*Must have low water pick-up)

[bayouboy2]

i have a 10" slider j/p a 6" allison it did best with both on stock lower 28p chopper

Give us more detail about the engine, such as 2.0, 2.4 or 2.5, what gear ratio and what lower and we can give you suggestions to tweak your setup. Baseline #'s on its current setup will help us guide you also. Gps speed, rpm, and design and pitch of the prop.

you can do much better with a lwp vs stock lower .so you are at 16 back...? i put a 12 on mine and it didnt really help till i raised the motor a lot, to like 1" down. you will be suprised when you get the prop in the air how much it helps the motor spin up

[bayouboy2]

first tomorrow bob's lwp going on it it currently has a 10"slider j/p all the way up prop shaft little below pad fixing to go back with the 10" slider and the 6" alli j/p thats where i got the best results 64.7 mph @5800 rpms but had stock lower and the motor was up bout 1"1/2 on the j/p the manual 6"was all the down just picked up the motor a cpl bolt holes spinning a 28p chopper new tried with the 10"setback with 24p chop with alot of cup got 59.1 @5500rpms with a cone even with pad...ran 28p chopper cone even with pad 5500rpms @ 57.3 mph

[bayouboy2]

it looks like it like all that setback ?

[pyro]

With the power you have available, and the speeds you're running, it doesn't need to be up as high as most might typically recommend, as the hull isn't going to be flying high and dry where the increased motor height can work its magic without excess slip. You'll notice more bow lift and better response to positive trim when it's lower, but better handling and perhaps more speed when it's higher. Too high, and your bowlift will be weak, and slip will be high-- RPM will increase but speed may not. Find the sweet spot.

[bayouboy2]

i think i'm going to go back with the 17"setback with the 10"j/p like it is and put the motor down on the allison j/p and run it with the cone and see what happens there then if need be come up a lil bit on the 6"alli j/p might find the sweet spot there ? dunno because i only have a stock 150 merc. on her.

[bayouboy2]

going to be putting some ponies on her over the winter for the summer and she will scream & fly fa <<<<<<<<<<<<<<<<<<<<<<<<<<<

Vultures not only like alot of set back 12" or more. But they require alot of HP to really perform and fly 220+++. I had probably one of the fastest Birds going. Thats Right (on the board) (motorheads Dad) now owns. And I believe he never changed my basic set up other than a new Coosa transom. And I believe Michael added a water deflection plate to help it break loose faster. I believe he was easially running in the mid to high 90's.

[bayouboy2]

HStream what motor you had on her HP?

HStream what motor you had on her HP?

I had a highly modified 225 promax (260/280 HP) that pushed it 92.. But I did a 2.4 that was pumping around 240 that was on it when Wayne bought it and the numbers were in the high 80's (87 ish.) Wayne bought a modified something that claimed 300 hp and his numbers went into the mid to high 90's maybe even knocking on the tripple didget door.

[bayouboy2]

was that a drag? because i would like a 300hp but i run around like a lake boat not always in the corner are have to keep my rpms high

[bayouboy2]

if i could build a 300hp motor that you can run all day

[bayouboy2]

what prop you were using HStream1...?

[HStream1]

You have a ways to go buddy. First what has been done to the bottom? And the list goes on and on to get a Vulture to safely run in the 90's or low 100's. It's alot more than pure HP.

Big ear Copppers run extremely well but the fastest I ever ran in it was with a cleaver.

And when you can build a 300 HP motor that you can run all day day after day without alot of PM. Then you have placed yourself right inline with some of the greatest engine builders of all time.

[bayouboy2]

Well i guess i'm asking sence you owned one what preps. do i need to do to the bottom among other things and yeah that 300 comment thats wishfull thinking.....lol never happen but yeah i plan on a 260/280 for her cause the bird has to FLY

[HStream1]

No one knows anything about the boats condition other than what you have posted. What is the condition of the core? What is the condition of the transom? has anything been done to the bottom (blueprint?) or is it stock with the factory hook? What year Vulture.

How about some pictures of what you currently have. How deep are your pockets to make a Vulture run fast safely?

A vulture is a very nice boat and was originally designed more for liesure running and moderately fast. But to make one really fly?? There not like a VKing or HST.

[bayouboy2]

it's a 79 flat pad no hooks that i c no it has not ben blue printed that i no of are what is blue printing involve in the guy i got it from painted the whole boat trasom is new, new stringer everything looks sound no sub floor been guted out......

[HStream1]

I'm not trying to bust your Bubble. But prior 80's Vultures were bad news unless redfone right. Like i said pictures will help.

[That's Right]

Right on Bud.

I think I may have somewhat of a unique Bird, it flys high and safe. My middle son has a Vulture as well, he has a 2.4 200 on it, Bob's cone & LWP, he is running about 75 mph.

Dam right you do Wayne!!! I was proud of that boat and the way it was set up and flew. I miss that boat more than any boat I have ever had and built.
