GPS as always :)

Yah neither can alot of other people, but i assure you it does, once I get it in from the seat refab I will get you some vids of it.. It is a solid 77 mph, I have no reason to lie or bull**** about it, cause this has me kinda baffled, I wouldn't defend a point or try to figure this out if it was a lie :)..The boat only weights about 1875 with me in it... The motor was supposed to be a STOCK 1997-98 350 efi motor. It had a ASM tune when we got it, I added emi thunder exhaust.. So to be honest the thing might have a cam in it, but the previous owner of it said it was stock other then pcm tune.. None the less it screams. With the current gearing it will spin the 30 bravo to redline, if I knew of a number or hp formula to plug numbers in I would know about the real hp... Also the stinger is alot wider, flatter across the back and doesn't have as deep of a vee on it as your boat does, so i think it would make for a faster hull, also has a pad..

1875 lbs would be almost impossible in a 22 foot boat unless it was a flat bottom river boat.My boat weighs 2600 and it is a very minimalistic interior and rig job.

If you were 1875 minus 900 for the engine package that would leave you 975lbs minus 50 for the battery and another 75 for the fuel tank and than 100lbs worth of interior than you would only be left with 750lbs .

Now i assume you weigh in at least 150 lbs that would leave 600 pounds of glass.

My boat runs on the last foot of its rounded v at 60. I used to run with padded bottom 21 scarabs that ran the same speed with the same 260 package.

Heck my old 19 with a stroker small block and an Arneson drive is only in the mid 70s for speed.

I think you need to borrow somebody elses GPS.

This was with the 28 pitch, had to stay out of it some to keep it off the box, spinning a 30p now with different(higher gears) still on the box... So that means it picked up mph,, That run there was well into the 73-4mph range on gps as I recall... The boat is 20ft, I come in at about 215lbs

1500lbs dry, I will go out and say 1950lbs.. There was over 110 lbs of sand foamed in from the factory, that was removed. I run on the last foot also. My GPS is just as accurate as anybody else's. I would hope your boat could run with a 21 scarab considering it is 19ft, doesn't weigh as much... i don't know what to tell you. I am not trying to start a pissing war here.. This is facts. I have came up with 6% slip, the boat goes without a doubt 77mph or better... I am sorry if you stroker boat isn't running better then 70. This boat went 50 gps with the v 6 in it.. Again the v on this thing is no where near the degree of yours, I am wider then you and have a pad...Might want to check your facts on what is up on the stingers(202) It is a 3 man seat thats it, no cabin no back seats...

Nice looking old Stinger for sure

.But i still highly doubt 1500 or 1900 lbs dry. That would still only leave 500 to a 1000 lbs for hull and rigging after you back the motor package weight out at 900lbs .Maybe 1500lbs for just the hull minus motor package which would place you back at 2400lbs with the package added back in which sounds about right.

These boats were not balsa cored carbon fiber lite weights.

77-80mph is about another 100 to 150 horse from 73-74mph.

Did you raise the x dimension on it and what kind of power do you think you are getting out of you engine?

Just curious because i would never dream that the stinger would be such a fast and efficient bottom.I know it is not a real deep v and has a pad but just find it hard to believe the speeds you are saying and the slip ratios agree with it.

I brought up running with the old paddd bottm 21 Scarabs as a reference that the padded bottom did very little to add to the overall speed over my convential rounded v bottm i have.

So what speed do you think that it should be running?? There is the weight of it right there in that link. Where are you getting 900 for the engine, a small block with a cast iron intake is about 600lbs this has a aluminum intake and aluminum manifolds.. And the sand that was removed out of it 100+ lbs there...So I am prob in about the same weight give or take 60lbs from the 6 banger And your saying I need another 100 hp to get 3-4 mph, your crazy, a prop change will do it if you can turn it, this thing can swing the 30 no problem(@ 77+mph).. My buddy has a heavy ass 24ft chap villian 3 and runs 57-58 on gps, with a huge deep v, with a 23p mirage prop threw a bravo1 1.5 gears.. And stock ass 330 hp bbc... I have walked on a 22 velocity with a decent motor( BBC400-10 hp)-Bravo drive. So that would mean he wasn't running 70 with that?? .. Also a few 28 formulas with twins, a 18 donzi with a healthy engine in it.. We didn't touch anything on the boat as far as bottom or x.. Again i don't have a clue what kinda power its making, but app more then we thought.. How much can it make its a efi small block with a tune and decent exhaust... Julie at throttle up is the one who rec the prop pitch(28) we are running, said it would be the one with the orig 1.98 gears... Well it was close but wasn't it, so app it is making more hp then we had told her which i believe was 350.. Not only that we have since dropped to a higher gear, are spinning a bigger pitch prop again to the redline... Believe it, it is fast, runs every bit of what I am saying it does. I don't bull****, the prop slip calc is matching what im saying.. I just asked if it was possible to have that minimal slip. Like I said I will show you it on a gps when I splash it in the water, you can buy me lunch....

I'm familiar with those Chris Crafts. That model boat with a closed in transom and a V-8 3.6 liter Evinrude 300HP stock runs 83 MPH. That's 15 years ago with 15 year old prop technology. Granted, the outboard and the 24 inch B-bracket weighed approx 550 LBS + 65 LBS. This speed was attained with 2 180 LB men on board and 30 gals of fuel. On the trailer, rigged less engine you could lift the bow of the boat over your head. It has a large flat pad and is a semi-V. I beleive the boat runs just as stated. You can't even compare a scarab to this boat. YOU WILL get smoked clean out of sight.

Thank you :drink:

I clicked on the 1988 202 specs and it showed the weight at 2300lbs dry,I think the 1987 at 1500 lbs is a little low once you factor in drive ,gimbal ,motor and rigging plus why is the 87 800 lbs lighter other than just a error in info. In comparison my buddies boat that was a actual 600-700 lb hull minus rigging,motor etc was a potato chip (1978 southwind drag tunnel). The sunlight would shine right thru the fibreglass it was so thin and you didn't dare walk on the bow at all as it would crack or collapse. Everytime you drove it you had to patch something back together as it was fragile.
AS far as does your boat run 77-80 mph,I believe it could and am not calling you a liar or anything,I just wanted to put the weight thing in perspective,Smitty

So kight that you can pick the boat up over your head on the trailer. Yea maybe if the stern is hanging off the trailer bunks 6 feet.

If the boat was truly built that light with the old mat and roving materials from back in those days. The layup would have to consist of one skin coat of mat and just one layer of roving and call it done.
And i am quite sure the Chris Craft workers were not using as little resin as was needed for wet out.

As far as the engine pacgage weight here is the specs for a 305 package deduct 100 lbs for your weight savings with the alumnuim intake and manifolds puts you at 846lbs for the package.

83 mph from a 300hp outboard is possible . Your talking a whole different animal with a Raised X dimension and a 450lb weight savings.

But 15 years ago was that 83 on a speedo or a radar pass.

Also your claim of a solid 80 mph is a long ways from 72-73mph.I can see low 70s if the engine is making 325 hp.which i think with the exhaust and cam modifications is about there.
