Vulture setup
Been lurking for a while, but this is my first post. I have a 78 Vulture and have run into a speed barrier of 75/76 MPH. I would like to see over 80. The boat has a 94 200 xri on a 5" hydraulic jackplate. The best prop I have found so far is a 24" small hub trophy. I have tried Merc choppers, cleavers and several Yamaha drags in the 24"-26" range and all it seems to do is slow me down a few MPH. Is there anyone familiar with the Vulture that can help me out. I have bought some 6"/8" adjustable set backs for myve I just jackplate, but haven't gotten them yet. Have I missed something real obvious or is 75 all the vulture is good for? Thanks, proud to be a Stream owner, Dwayne Laramore.

Re: Vulture setup
Welcome to the madness.
There are a lot of variables beyond props in setup, and not all props will run well with the same setup.
Do you have a low water pickup and or a water pressure gauge?
With neutral trim where is the propshaft in relation to the bottom of the pad= engine height?
I do not have a vulture but would imagine more setback will help, I run 12" on my 20' vegas xt.

Re: Vulture setup
Thank you, I am learning quickly what it is like to be a member of the slightly more expensive "big motor club". Lol. Right now it seems to run best somewhere around 1 1/2" to 2" below the pad. I am running a Bob's 200 case with lwp and water pressure gauge. Boat has been recored and is structurally solid. It has a small hook from front to back of the pad " 3/32" over a distance of the last 4 foot" I have raced the small eleven and twelve foot kneel down boats ranging in speed from 60 to high 90's. This is my first big boat and feel like it should run a little better than it does right now. Like I said in the original post, I am looking for just over 80. With the hydraulics I have run every prop through the gauntlet of hieghts. Mostly what I see from the pictures my friends took the boat looks too heavy in the water with probably three feet touching at speed. Seems to me like it is running on more than just the pad and shouldn't be. So my next If I have left anything else out that may help let me know, and I will fill in the blanks as best I can. Thanks, Dwayne.

Re: Vulture setup
This is a low 80's pass and I still have a lot of boat in the water.
How much trim do you need at top speed?

Re: Vulture setup
How much set back are your running? I would try at least 8" or even 10" set back. I have a 77 Vulture with a 10" jackplate but I have yet to run the boat but these boats do love alot of set back to get em flying.
I know a guy that had a 79 with 10" plate and a 225 merc that did just over 80. Took him a while but with the right combo he got over 80. I have seen a 90+mph vulture too. Had a 275 rude on it. Not sure if there was any work done to it or not though. These hulls will go fast, Just need big power and lots of set back.

Re: Vulture setup
I don't have huge horse power so thats out, but I am waiting on my extensions to get here so I can put the motor at either 11 or 13 inches of set back. I appreciate y'all helping me out. I am mobile most of the time and don't believe I can post a picture from my phone. As far as the trim question from 77viper it looks trimmed up at speed. As soon as I can I will post a pic or get it to someone that can post it for me. Thanks, Dwayne.

Re: Vulture setup
Okay I am technologically challenged, stole the wifes laptop and tried to figure out how to put a pic up here but had no luck. Could I trouble someone here to post it for me? I can send it as a text off my phone or as an email, whichever makes the most sense. Thanks, Dwayne

Re: Vulture setup
Send them to me @ chetmolson@frontiernet.net and I'll post them for ya.
I would start with 11" I haven't run extensions with a jackplate but I have heard of bolts loosening up so make sure to double nut all bolts.

Re: Vulture setup
Here ya go.
Your attitude looks good, the faster you go the more it will come out of the water due to water pressure on the hull.
