Well Checkie(snakebit) I thought we would enlighten people about you and your so reveled mods-man-ship(didn't seem like they were so well recieved). Here's a eye opener for everyone, of who we are talking to on this site.

One of the things that's unique about the setup is that the engine is in a stock bravo location. We used the extension box to house the transmission. The boat interior is stock. I didn't want to move the center of gravity forward at all. The prop is acutally 53" from the transom so we have a big lever. The boat "thinks" it's 3' longer than it is. This boat stayed in the mold a little longer than normal but otherwise it is a normal layup. We did add a gusset to the stringer where it meets the transom for a little more support. I was used to driving a left hand rotation bravo so the #6 is also left hand. The gear ratio is 1:24 to 1. I have a 27pitch 16.5" diameter 3 blade and also a 29 same diameter.

Drive height took a little more trail and error. The boat left Checkmate as a blank. We did all the drive and engine rigging and installation. Merc. racing told us where to mount the drive but they were way off. it was way too high to start. Eventually I had to have the transom filled and we lowered the drive. I am using a 3" spacer which is the largest they make. We could probably go up a little from the current location but the boat handles so well and is so stable can't really see any reason. If I want to go faster, I can just turn up the boost

I suspected you had the trans in the extension box, So you have a twin turbo charged set up. It kinda indicates that were your exhaust dump out the transom. Very unique it makes a statement.

While other Venoms sat on the famous S&F (OHHHH) sight for months and years and could not sell -- That one which everyone had fun with sold in one week. Goes to show ya who had the knowledge there.
The fact is you opened a thread claiming you would gain 5 to 8 mph with a couple of engine mods.
Now you want to back track and say I was looking for low range mid range,because you refuse to admt that you like me no nothing and you wasted your money. The rest of this is all B/S when everyone who knows anything about anything said you were waisting you time and money -- you still decided to do it.(Your a big boy and can spend you hard earned cash as you see fit)
When I suggested you had done the same you chose this. Something that I love So keep it up!!
Weren't you the one who suggested we should NOT post on each others threads!!! You need not worry -- You are always welcome on my threads I am just that knd of guy!!!
By the way how is that 80+ comming have not seen much posting lately, have you taken my advice and have you started that wheel work YET.
Hey there is always the back seat the bow light-- Any lettering on the boat that you can remove - You go get em double j !! Who knows maybe we will call you triple j before we know it!!

Now checkie tell the truth.....the Venom didn't sell so you traded it in to Wildman for your Check. He than "de-snake-afied" the poor boat so it would sell.......Just cause you wear panties......there's no NEED to get them in a WAD !!!!!!!!!!!!!!!!!!!!...........lol..................

Sorry Sir You can ask people with Knowledge!!! He never touched the boat. Randy does not touch boats that are in mint condition, The boat sold in one week,by the way I took this from you -- I will do 80+ in my Pulsare thread

He said I guarantee (I doubt he said that to you) that I can get you in the 80's. So the game plan is to do the ecu mod , lightened flywheel, poppit valve and a Hydratec exhaust tuner. So I'm thinking that this would be just the perfect x-mas gift for the wife...yeah right.. seriously I'm thinking about the mod's for my x-mas gift. What do you fellow Checkies think?

I got the tuner and poppit valve @ Hydrotec and the lightened flywheel and ecu mod. thru Simon. It's about $1300 for parts. I got it back today so I'm ready to test except........... it's gonna be a high of 48 and cloudy Friday, but Sunday it should be 70.

Allison --two people 115 mph I must say you have a vivid imagination!! Now prove me wrong!!

Hey H/D when are you gonna break the century mark

As I have read this entire thread I have come to the conclusion that to get a C/M to do 100+ you have to make major modifications to both the hull motor and location of the motor. The Outboard versions will never do 100 without the same major modifications to the hull. I say we have the best of all worlds with C/M great looking - good running boats at a very reasonable price. For those who wish to go faster there are other avenues. I for one am happy that my boat runs a solid 85 mph all stock without having to strip it down and create something C/M simply is not (A race boat)

 

[Double J]

Allison --two people 115 mph I must say you have a vivid imagination!! Now prove me wrong!!

I don't need to prove anything to you. I have been driving Allison's since 91(the first one I purchased new). A Allison SS will run over 120 plus with one person(theres one that has ran 126). I don't have pics but it ran 8500 rpm's with a stock 280, with a stock labbed lightning et 30, with the wife in the boat. At 8000 rpms it registers 110 on a Livorsi gps speedo with her next to me. Do a prop calculation and see what you get. What I'm been trying to tell you is that you never know what a set of mods will do until you try. I was skeptical from day one that it was gong to achieve these results. I only needed less than 3 mph to bust 80(which you say is impossible). Instead of damming everybody and everything I would think you would be you be positive as to see what any mod would do(I am).I posted honest results before and after. See I'm not a know it all like some people perfer to come off as. If you feel that this Fury prop will gain 4 mph on a 2400, buy it, send it to me, I will do a honest test and if it gains 3 mph I will buy it from you(on the Mercury site it is only a little over a mile faster than a Tempest plus.) No BS. Balls in your court.

It is a twin turbo setup. There are pictures in the "show me the horsepower thread" We worked backwards as far as the exhaust. I wanted the pipes to be under water at idle speeds so we placed the holes for the tips and fabbed the exhaust pipes to fit. Around docks it's quieter than a stock 330.

I knew it had to be quieter since it was a turbo but that is nice. I would love to build a similar boat one day.

I will correct you on this you are 100% WRONG !!!! All the Checkmates I have listed that run 100 plus, all have a stock factory hull, stock engine location, and stock drive location. Every boat also has the full cabin and cock pit interior the boat came with from the factory.

Their is one boat that has been altered and thats check253 300. I do not no whats in his cabin and the bottom was corrected. But I do belive the engine is also in its stock location. But then again does his boat even matter because he is shooting for 114 thats 30 mph faster than any O/B

I never said it was impossible -- I just said it was impossible through the engine mods, but I believe if you put your efforts int your prop you will achieve your goal, (Labbed Fury) or my favorite a Masco 25 labbed 4 blade, The rest of the this stuff is just the two of us bustin each others chops and providing some good for the members!! Come on it's winter!!! Where is your sense of humor?? I saw the pic's your boat is beautiful best of luck but I would still get my money back!!

By the way Venoms rule

Hey H/D when are you gonna break the century mark

I did it yesterday... Here is how I did it.

I put 30P Fury's (labbed of course) on the twin 300XS' with full Simon upgrades (that are totally useless). I then put a 26P Fury (labbed of course) on the 280ROS TROLL-ing motor. That got me to 99.98 MPH at about 1pm. I then decided to wait for colder weather (better performance, right?)to roll in at 5pm (by this time the forecast called for 28* temps vs. 34* that it was at 1PM.

While I was waiting, I put two HUGE Mercury Racing stickers on the side of my 2100 figuring that the "cool factor" alone was worth .01 MPH.

At 5PM, almost dark, I was able to pull off a 100.7 MPH pass!

My next goal is to do the same with a 2400.

If you would like to try my 26P Fury (labbed of course), just let me know.

on the twin 300XS' with full Simon upgrades (that are totally useless)So you are finally realizing that. I then put a 26P Fury (labbed of course) on the 280ROS TROLL-ing motor.Son-- You could not handle a Diamond 2.5 -335 H.P.Ros mota the exhaust noise would scare you, Stick to your nice efficent 300xs
Can you imagine a 2.5 280 on a bow wow rider hehehhe

That got me to 99.98 MPH at about 1pm. I then decided to wait for colder weather (better performance, right?)to roll in at 5pm (by this time the forecast called for 28* temps vs. 34* that it was at 1PM.

You can't put stickers on your boat -- They will inerfere with the bow wow cover anyway Simon would be pissed at you. (Put his Decals on-- I saw the new ones they are very nice
Mercury 300xs isn't a motor until you send it to him!!

Simon racing --
"Spend 2000 and I will give you a mph"


At 5PM, almost dark, I was able to pull off a 100.7 MPH pass!

My next goal is to do the same with a 2400. Dont go to Simon just brorrow the chit from double J

If you would like to try my 26P Fury (labbed of course), just let me know.
Fury and props are to easy for a guy like you --Na your a mota expert -- Keep workin on that!! After all your partner picked up a mph -- maybe you will do better

HD

The Lake was frozen yesterday -- You were riding a snowmobile and dreaming about your boat!!
By the way way a bow wow rider will never run a 100 no matter what you use.

I believe you had a post or a thread where you are trying to find a tight cover to hide that whole in the front of your boat and to make it go faster -- Lab that cover get it really thin -- I mean the skinney -- that will help!!

 

[check253]

I will correct you on this you are 100% WRONG !!!! All the Checkmates I have listed that run 100 plus, all have a stock factory hull, stock engine location, and stock drive location. Every boat also has the full cabin and cock pit interior the boat came with from the factory.

My hull had not really been modified. It was blueprinted but that is just making sure that the bottom is straight which is how the factory wants them anyway. I've already seen 114 on gps but am looking for something between 115 and 120. We'll see.

Thanks for making that clear I try to keep up with all the fastet I/O's I know you post on oso some. You might have the fastest cm so far. I have been looking into some here say on another one.

The best part is Baja's have a 90 mph club the way some of the Checkmates are running we might need a 110 club

Check,
just curious are you running a Herring prop or the merc props? Have you tried to raise your drive hieght 1" or 2" and try a 4 or 5 blade cleaver for more speed? or a 4- blade cleaver at your hieght. I agree a deeper x dimension is more stability just wondering why you decided on 3-blades obviously they work at your X .
I know $1600 a prop and up for the #6 makes for expensive testing. I have seen alot of race setups and most are swinging more blades.
Just wondering what you have tried.

Also I have questions about your old 253 What kind of bravo and lower unit were you blowing up. I have 7 runs on my new engine and the drive is holding up fine so far,xr upper with max machine top cap Imco Sc lower careful shimming and syntitic lube. I feel I have enough break in time to put it over 100 next time out. The first six times I did not have enough prop 30 bravo and I was breaking it in and some jetting issues. when I put it up there I was bumping 6000 rpm in the mid 90's. I have a 34 lab on it now w/1:50 I finally hit the spot. I still wish I would have gone with a 1:36 but I didn't know I was going to bigger power at that time.
I ran it once but it was a windy day little to much chop found a little good water for 98 on gps. I am sure on some good water I hope to put it over.

So what I am wondering what set up put your over? I now they have more drive options these days and the better drives just started coming out when you went over 100.
I would like to hear some of your 253 details.

Thanks

Check 253 -- At the end of the day what was the cost of your work if you do not mind me asking.
I am asking because alot of guys on other sites mock C/M's for quality of there product. I am one who is very happy that someone has taken a stock C/M hull and done remarkable work. I can only assume that the cost for these speeds can be achieved for alot less and still having a quality hull.
It is obvious that the hull has standed the test of the speeds you are going.
Have you done Poker runs?
Have you run the boat in any of the circuts out there?
Thank you for some insight about the C/M hull that some of us probally never thought existed this was a good thread.
My last ? is. What do guy's in Cigarettes and some of those other million dollar vessels feel when that Flamer makes them look like they are tied to a dock??

 

[Big Red]

You cant really compare a Checkmate to many other brands like Cigarettes. A Cigarette will stomp a Checkmate in the ground on resale and build. These boats are heavy and can crush 5 foot chop and never miss a beat. The one I like most is the Cigarette Bullet which is 31 foot and closest to a 300 Convincor. But it takes twin engines to push this beast and big , big money to get it close to 100.

Check 253 has done a lot of different things with his boat along with twin turbos. He also did alot of fabrication.

I feel 85 to 90 can be obtained with in reason on a reliable pump gas engine at a decent cost in a 300. But when limits are pushed to 100 and way over like check253 is doing it takes money but then again most 35 foot boats running 100 have 2 900hp engines or bigger.

Checkmates are lake boats and are no match for ocean poker runs.

I do have both 3 and 4 blade props Also tested a 5 blade. Retail on a new merc prop for a #6 is over $3000. Herring gets much more than that for one of theirs. My slip numbers with the three blade is under 10% which is very good. The three blade accelerates harder as well. The only advantage that the 4 blade has is at cruising speed. I could probably go up a little with the drive at this time but everything works so well, I don't feel a need.

My old 253 had a regular bravo drive. It had been extensively modified by Dick Simon marine out of Calafornia. The first one they did for me lasted over 100 hrs. but they were never able to duplicate that success.
i was using the 1:36 ratio and turning a 28 4 blade hydromotive QIV. I also had the bottom blueprinted as there was a little hook...about .125 but that is more than enough to slow you down.
