"TOP SECRET CHECKMATE" PIC'S

[boatman4021]

By the way, I was talikng to a friend today about this thread and some of the things that are bugging people about this new checkaja, bamate, beckaja, or what ever it is. He explained things in a different way. How many of us when we were younger, focused our attention on some great looking woman with that perfect body and all of the qualities of a good wife, and then ended getting married? And then as time went on, you knew that you had made the right choice. Now after a few years go by and a couple of kids pop out, mommy starts to put on a few extra pounds and get a kinda round look to her.(the euro look) Now, she doesn't look the same, but she still has all of the special QUALITIES of you perfect mate. Do you love her any less? NO. Do you cast her away? NO. Do you turn your back on her and talk about her? NO. Now the thing to remember is some people are attracted to the plump or round woman(euro style) and that is kool. So why don't we all just watch and see what happens in the next few months. Remember, it ain't over until the fat boat sings! boatman

By the way Red, I think it was my prop that broke your outdrive. That was an outboard prop. That I/O just didn't have enough chit to handle it... boatman

Just came across some info that might be of interest here...

Found a Powerboat magazine report (12/1997) that tested the Baja H2x with a 502 (415 shp) at 71.5 mph @ WOT.
and Powerboat magazine report (07/2001) that tested the Baja H2x with a 496 (425 shp) at 72.6 mph @ WOT.

So I see no reason why the Check with 425hp shouldn't run into the 70's.

Oh yeah... Also found this compilation of boat test reports that you can download:

WOW, that compares the Baja 272 to the Checkmate 253 or 270. with a 502 in it the Baja is faster???? I always thought the checkmate would have been faster than that!! I cant believe the 253 with a 502mag is under 60mph, that dont seem right.
anyone out there got one that can compare? (stock motor that is!)

 

[boatn70]

aaahhhh! but look at the inconsistancy in the Eliminator 250 Eagle, two tests with 502mag one at 80, one at 78.6 then add 55 hp and drop to 77.8.

that alone shows you how much water conditions, air temp, driver, prop and all the variables can change outcomes drastically (im using 2 mph or more as drastically different considering stock powerplants)

 

[Big Red]

I only got 38 with my test

 

[Gimme Fuel]

Mine 253 with the 502 MAG did 66 consistantly on GPS when I got it....by the end of the summer I could only get 63 out of her (Hence the upcoming re-build). I have the EMI exhaust and the K&N spark arrestor but I am not getting anything from them because the previous owner never had the PCM re-flashed to compensate. I know with my setup and if my motor was tuned and fresh I should be touching 70. I was mad that I couldn't pass my buddies 2007 bajunk 25 outlaw with a 496HO and headers (he does 71 on gps....If I had that power I would be quite a bit faster I imagine).

Boatn70--
The H2x and the Hammer were running down the lake (which is fairly long -8 miles) neck and neck. No doubt in my mind they were racing. I ran my boat w/ the 115 between the two, they couldn't miss me. Probably 50 feet between boats. Raced between 1-2 miles. Would that scenario allow a punk to upstage them? Afterwords, the H2x even followed me into the marina/cove/boat launch. He had that 'What-the-hell-just-happened?' expression on his face.

30" double cup over hub (31) at over 6000 w/ 2:1 gears. Internally bone stock w/ nosecone. Do the math. Just going by eyesight, the 115 went by them at a minimal 5 mph and probably closer to ten.

Again, its embarrasing for a big block H2x to get outrun by a 115.

What year boat model and size

No one likes to get beat, especially by a 115!! "Do the math" equates to 79mph with 10% slip. youve got a great running little boat.

I say yours is the exceptional one! they must have been running 74ish.

not bad for either boat running stock power.

 

[boatman4021]

msmile, I want to know what your secret is. I did the math! If you allow 10% slip, you were running 75mph in 20ft boat with a STOCK 115? A 21' Pulsare with a 225 is a 73 to 75 mph boat. My 20' Pulsare w/225 ran 76 with lots of set up work and prop testing. I don't care what kind of prop you use, 115hp is still just 115hp. Share your secret with us! Also, a 16' Pulsare w/125hp is only good for mid to upper 50's, maybe low 60's with some set up work and the right prop. Let us know how this works, I am sick of buying gas to feed my 225. I am going to trade it for a 115 and save some gas! By the way, before subtracting for slip, it was 83.87mph. I just remembered, Illmattic did run a touch over 80mph, in a 16' boat with a slightly warmed 200. Maybe if he had used a 115, he could have run 90!

 

[boatn70]

i ran the numbers with a 31" prop based on his numbers and his 2:1 drive, comes out to like 88 before 10% slip................

wonder how he does it?

 

[zstevens]

i didnt think it was a 20' boat , but wasnt it a fishin or flats ? i didnt read it that close . side note is this checkmates 1st time for using brand x molds ? how many past checkmate (pre DS) are still cmate empoyees ? how many bj's are now cmate employed ? makes me wonder about past practice , skills ,quality ? hopefully will not be less than in the past !

 

[hotdaddy27]

Story #2. (I don't make this stuff up). A brand spankin' new H2x with 502(?) power was racing a nearly new Hammer with 454 Mag power. I decided to join in and beat them both with a 115 (not a 150) Johnson Fastrike on a 20 footer.--That's embarrassing.

We don't know what the boat is....I doubt it is a Checkmate with that kind of speed out of a 115.

It may be possible with a 20' boat, just not a 20' Checkmate.... Unless it was an Anorexic one! LOL.

I think the correct number is their are 2 baja labor employees working their that came from baja after the ohio plant shut down. I know their are a few people working their now that used to work at Baja one time or another. But worked for Bill Combs before Smith took over

 

[Big Red]

My neighbor has a small bass boat with a 115 17-18 foot and he has played with it for a while " since 85 ". 2 people 1/2 fuel 60-61 he said the best he ever got out of it was a cool sunday morning light riple 67. He also said just him light on cargo 65 all day any day.

Like it, or stick it!

I personally hope this site doesn't become a Checkmate/Baja site
and it's starting to get that feel with all the beckmate talk and the
baja guys rubbin' up and get'n cozy with the leader here
and if the poker run becomes a combo deal I will scratch it from
my summer boating agenda - there used to be something unique
about Checkmate's and this Checkmate site and if the Baja haha's
start flooding in, I'll be Checkin' out and this will be just another
run of the mill boating website with nothing unique about it!
That's my take, like it or stick it!

I boat with people with Formula's, Baja's, Rinker's, Wellcraft's
and they are all my friends but I have never been on a website
for any of those makes - I am not interested in any of those
brands and have no interest in how they are made, how they run
etc.. I am into Checkmate boats and that's what interest's me!

Good summary of why all of this other BS is unimportant to this forum as things move forward.

The math would be: (The fastrike/intruder series had extra rpm over regular v4 115s) 6250x30=187500/gear ratio (2:1)=93750x.000947=88.78 before slip. A good dialed in outboard will run 8% slip or better. x.92=81.67. Not factoring in the double cup the numbers ring true. I had that set-up for a summer and a half and continually ran 81-2 on the GPS that I carried almost everytime out. Had a Yamaha v4 briefly (2 months) and ran 82. The best run reached at several occasions was 83. Hull= 20 foot (20'2") AllisonCraft Super Sport. (747#)

Yes, a 115 can swallow an h2x.--by quite a bit.

food for thought: using the 10% rule; 83 mph / 11.5 gallons per hour= 7.2 miles per gallon--@ full throttle. This was a carb motor not direct inject. Throttle back to 70% and get? Switch to DI and get?

more food for thought: This thread lists a h2x @ 3600lbs dry. Add 200# for driver and 150 fuel. 3950/415 hp (502 mag)=9.51Lbs per hp.
The 115 was 1070 plus driver and fuel. 1420/115=12.34 lbs per hp.

As everybody knows, speed is about hp:weight. How does a boat nearly 3 lbs heavier per horsepower beat another? Answer: H2x had poor engineering.
