Fastest sub 20' checkmate hull

[supergenius74]

Hey all you checkmate fanatics, I want your opinions.
Out of all the hulls checkmate has ever made under 20', which one is the fastest? I am contemplating an eventual upgrade on my staflite in the future to a 3.0L Opti motor and taking my little brideport and putting it on something that is dangerous. I Like the predictor with a brideport that really flies, is there anything faster? more stable at high speeds? something that is very hydrostreamish with a high revving 2.4L engine...

[LAPLANT]

I THINK A BRIDGE PORT ON A PREDICTOR WOULD BE FUN
BUT IF YOU HAVE A BIG OLE BRASS PLATED PAIR I WOULD FIND A MX 13 OR A PLAYMATE:rof:

[illMATTic]

predictor would be the lightest and most stable. :D

[WalkWithMax]

I have a 1984 Panther Vmate II with a 200 merc. This boat is a blast, but pretty crazy above 65mph. Does anyone know if my boat was a flip of a predictor or??

[83PREDICTOR]

PREDICTOR

[illMATTic]

the v-mateII was pre-predictor. last year i think was 78 and the first year of the predictor. both have a pad and are around the same weight but the predictor may be faster due to the v-mate's seating being further toward the bow. however you could correct this with a bit more setback.

if you are building for speed i would stick with one of these two.

[illMATTic]

here is somthig to think about..............

i ran this through the prop calculator...................

6800 rpm, 1.87 gears, 32 hoss triton, 15% slip, 92 MP freakin H!!!!!!!!!

with my stock 200 i was able to turn a 30 hoss 6400 with 15% slip. I am sure you could turn a 32 6800 with that BP. :eyecrazy:

Oh man! I'm getting all excited!!!!!!!!

[supergenius74]

sorry I got you all worked up illmattic....hehe, If a 300 can push a heavy 1400 lbs boat to 90+ then i have no doubt my BP could push a light weight predictor to that speed. What about a starfire, if I didn't know the better I would say they are the exact same boat as the predictor.

[illMATTic]

not sure if a starfire has a pad but it is around the same size. you just dont see too many. i bet there are a handfull of boats in the 16-17 ft range that would do 80+.

[cmpulse170]

I wonder how fast I could get my Pulse 170 to run w/ some mods on the 200HP EFI hanging off the back.:D

[supergenius74]

How fast does it go now with the 200? Those pulse hulls are heavy, the 185 weighs as much as my staflite.

[Great East Predictor]

I might be a little biased on this one...but the predictor with a bridgeport is an awsome combo. This thing is wicked stable for a small boat. I just finished breakin the mota in and got 85.5 last week (yes illmattic, i know i need a hoss)....boat gets a ton of attention and is a blast to drive.

[cmpulse170]

SG I haven't gps'd the boat yet since I'm still messing w/ props and engine height. I can bury the speedo(80MPH)w/ the 25P Tempest plus I just added. The prop Calc, says I'm only running about 70mph. I can only turn 5800 rpm's since I've got a rev Limiter.

predictor is shorter than the v-mate ii. "the nerd" has the checkmate version of your boat. your's was built by quinn's marine in pefferlaw.

[Blizz]

We had a panther on the lake with a 2.4 Bridgeport that would run into the 90's this was back in the mid eighties. And as stated earlier any 15"+ boat has the capabilities to run 80+ with right motor and setup.

[winter]

A starflite is heavy but it's a very good hull, esp. the ones with a stepped hull. Then again you are looking at a sub-20' so they dont count. I wouldn't rec. this as it was not a stable ride, but i once owned an early 70's MX16 with a high strung tower of power 150 that saw 80mph with a vintage but well worked 2 blade bronze prop. I'm guessing the 150 was tweeked to 180+ hp but it was an incredible handfull to drive. It may have been a set-up issue, who knows. :shakehead: Good luck witht he search, i'm curious to see how it all turns out!

[Blizz]

A fient of the family had an MX16 started life with inline 150 then went to a 175 then a 225 and finally ended up with a 2.5 BP. And as stated by Winter was quite a handfull but an extremely fun ride:thumb:

A 2.5 on an MX16?! YIKES!!! :eyecrazy: I'd love to know what speed he was cookin' at!

2.4 bp

[supergenius74]

Wow great east, 85 and you aren't even running the best prop yet? You are going to hit 90 aren't you, let me know when you do, what RPM you are turning, everything i have researched on stock BP motors is they make their peak HP at around 7K and up till about 7400 are still doing good then they drop off. I am never going to get rid of this light weight high power engine, it's just awesome, I just want to find a better boat for it for the future. So you are stable at high speeds? even my starflite gets squirly at 70, I have heard you can drive through it but I don't have enough HP to do that.

[Blizz]

Yep sorry for the typo 2.4 BP not sure of exact speeds as this was in the early to mid 80's so he only had the good ole dreamometer..

I got 86 last year. :) Just haven't had a ton of time to play solo yet. Hopin to hit 90 this year, that's the plan. I'm right around 7k at 85. Very stable at high speeds...i can seriously let go of the wheel at 80.

[msmile]

I'm an outboard guy but the fastest sub 20 checkmate would be an i/o. There is no replacement for displacement. Phrased another way: There's only one thing better than cubes...and that's more cubes. Local guy had a 19 or 20 foot checkmate w/ roughly a blown 750 hp. Blackhawk drive Mercruiser. The thing went 115ish, no joke. 102ish w/ same motor naturally aspirated. He never got the nitrous hooked up.

hats off to you!!! :thumb:

its amazing how everything changes @ about the 70 mph mark, the last time i was out, i had a 28 chopper at 1/2 below the pad, i dont know how fast i was goin'.. i forgot the gps, but the motor was spinin' just below 6k, holdin on to the wheel like nobodys bussiness, and i think i needed new shorts after it walked just a little bit, and that was enough for me that day, then 20 minutes later i got that stupid ticket!!!

illmattic drove this boat faster than i probably ever will !!!:cool: oh well, at least i can say it has been over 80...even if i cant drive!!:banana:

[supergenius74]

wow, that does sound stable at high speeds, I guess that is why they call it a "predictor" it's "predictable". I always felt like my MX-15 could go much faster but that the bigger engine would be too much for the hull/transom, and my MX had a small pad like the predictor. I think I am going to keep my eyes out for a hull only predictor project now. :devil:

[illMATTic]

hey buss, you may want to look into getting solid motor mounts. after seeing the ones i have now, yours seem a bit weak. solid mounts would true it up a bit.

[Mr. Buss]

actually i already got 'em,:thumb: but i havent had time to pop the powerhead off to put them in, i put the trim on the wheel, and i got a torque tamer to install, just runnin out of summer in a hurry....

[83PREDICTOR]

Mr.B, I would have thought that you could turn the 28 Chopper more then 6k. Maybe you need to take it up a lil more. Maybe a 1/2 inch above the pad.

[Mr. Buss]

Or push the pedal ALL the way down !!!!:lol:

[83PREDICTOR]

HaHa, that could also work. My bad.

[illMATTic]

you will be able to turn that prop at 6400 all day long.

i ran 78.1 with a 28P chopper
79 with a 29P mazco RE3
81.7 with a 30P hoss triton. i only got to make a couple runs with this one. i bet it had a bit more left in it.

all ran 6300-6400 @ .5 above the pad.

the hoss pulled like the 26P laserII and had MAD bow lift.

you'll get it, just takes a little while...changing to solid mounts will help for sure, once you figure it out you're really gonna love that boat.

Yep what he said ^^^^^

If I were to make a river rocket checkmate Ide beef up a predictor or SPORTFIRE. Add a wider pad, gut everything, make it a center steer single seat, Evolution powered OMC v8 Monster. In theory it would run well over 100mph, but Ive heard that shorter boats have a "terminal velocity" so to speak, where as a longer boat, although a bit heavier would run faster....??? Either way a Bridgeport on any sub 20' hull is gonna scream! Keep us posted if you decide to go for it!

Have you considered any other hulls? Ide love to have a small hydrostream, or even my sutphen w/ a bp.,...

Or my all time favorite ACTION MARINE

[illMATTic]

that BP on a 20' allison will do close to 90+. the grand sport only weighs around 850#.

LOL, true true. Well, kinda. I've been an outboard guy for years and only now have my first V8 I/O. I think there is a point where pound for pound, pony for pony, and I/O will be faster than an outboard, but it involves cubic inches and that means cubic dollars. :D My stock 250hp V8 in my Persuader is a dog by all accounts, but this winter i plan a big build up and maybe even big block power. I need 80mph in the worst way :shakehead: But that same amount of $$$ would be me a heck of a nice 300x merc that would likely do the same thing with 1/4 of the fuel ;)

[msmile]

I talked with the owner of that checkmate. It was just a tick under 19' (model?) Anyways, he had a 548 in it / blower. He said the boat hull was probably not intended to go that fast (?) and the front deck/dash would move up and down 4 inches at wot. Yikes. His competition was an Allison Supersport /280, which he blew off and a 19 foot Glastron CV19 w/ a 572 and tons of nitrous (250 hp added) which he also beat.

[supergenius74]

wow a blown 500 cu in motor in a little 19' checkmate, that guy should be a test pilot for checkmate. I have looked at a lot of hull options for my BP motor and the best would be a tunnel of course, I have always liked the the HST's and allisons, especially the GT-20 love that boat. But for me it's about speed and looks, not just speed. I will take the checkmate over any other boats, just for looks alone. I think going 85+ in a nice looking predictor that is practical and affordable with an iddy biddy outboard is amazing accomplishment.
