Yep, that's running' like a Checkmate. :coolcowboy: :D

Ive got some vids in the video section here from a radar run this passed October, but it didnt go that fast there....waaaay too rough.

I actually got it to run that 84 on the way BACK from there, LOL. Damn near no fuel and me and the gf in the boat.

Filmed with 100 gallons of gas on board, 95 degrees, flat sticky fresh water!

Really nice looking Checkmate there!!!

sabo that race fairing you have on there looks KILLER, nice looking Convincor

Still testing and working on the setup of the Punisher but it's now running 97+. Still looking for a hundy:)

procharged 572 about 950 hp ITS and bravo XR -2 sportmaster 1.36 ratio with hydromotive 30p p5x at 5400rpms 98.6 mph 2 people and half tank of fuel

That is getting impressive

Holy sh*t

The Checkmate section has been dormant for a while so I thought I'd wake it back up with my side project. The boat is a 1990 Checkmate Starflite with a Mercury Pro XB250. I just had the motor rebuilt with new rings, the #6 hole bored .15 over. With 11.5" of setback and the propshaft dead even with the keel I'm running 78mph @ 5800rpm turning a Mercury Trophy Plus 27 @ 5800 rpm. I'm going to raise the motor on the jackplate, swap out the helm for a SeaStar Pro 2.0 helm and try a Sportmaster gear case. With some prop changes I should be able to get the boat to run mid 80's!

2011 Pulsare 21 ft LD. 2010 Merc 250ProXS Torque master lower running 1.5 inches below the pad. Stock 27 inch Fury. 12 inch set back bracket plus about 5 inch for the jackplate. Runs 82mph any day. Have seen 84mph GPS a few times.

1991 checkmate 235 persuader GT with a 548 twin turbocharged bbc. Hundy plus ah couple.

Where do you boat in Ohio? I'm at Alum every weekend and would love to take a look at your setup and meet another fellow checkmate owner..

After installing the SeaStar 2.0 helm I got the boat to run 79.49mph GPS @ 5900rpm while at River Ranch a few weeks ago..and that was flat sticky water and 90 degree temps!!

Occasionally Alum, but mostly lake Cumberland.

Bring that rig to the Checkmate Owners Rally. It's the third weekend of july at Cumberland.

Can anyone tell me what to expect from a 2000 259 with a stock 454 mag will run?

Also a 1996 253 with a stock 502 mag?


Kinda looking at both of these. I know they wont be 75mph boats, but I won't be happy running 55-60 either.

259 with 454 mag will run 65 + or - 2mph
253 with 502 mag will run 67 + or - 2mph

these numbers are ideal conditions, correct prop, low fuel, 1 or 2 people on board

Is this going to be on cumberland again this year?

How fast has anyone had checkmate 235 persuader and with what horsepower?

A buddy had one with a 465hp 502 and it went upper 70's.

A good friend of my Dad's has one with a pretty stout 555 in it that runs 92

There is a guy from Ohio that has one with a twin turbo 540 I believe. He is running well over 100 with it.

They are a very fast hull that handles really well.

I'm looking for speed . If anybody finds him, tell him I'm looking for him. Thanks !

Yes. 3rd weekend of July.

well i've had my new to me 2007 270 496 mag non HO out twice with two different props same speed of 65mph. rev4 23p 65 at 5000 rpm. bravo1 26p 65 at 4600 rpm.

Went out again and did some more running and was able to see 67mph at 4900 with the 26p bravo.

speedo or GPS? very curious because with my boat I'm seeing just a touch over 60 with a 23P rev 4 and another mile or 2 more with a 25P mirage plus. GPS, speedo is about 5 higher but thats good for telling everyone speeds when they ask ;)

2001 checkmate zt280 496ho bravo 1 24 and I've seen 68.2 with just me and a half tank. Full tank and a passenger and it runs 65ish. Needs bow lift I might send the prop out to get worked.

My other Checkmate: 1997 Checkmate Pulsare 2400 Bowrider, Mercury Verado 300 Pro, Bravo One 24, Atlas 8" hyd jackplate; 70mph GPS.

GPS recorded speed of 75.5MPH @ 5900rpm last weekend with my 2800SX Outboard. Merc 250efi's, 25" of setback, Bravo One FS 28's!!https://scontent.fmia1-2.fna.fbcdn.n...0d&oe=5BFCC2E6

What's a typical 98 251 w/502 MAG rated at 430hp run normally?

30 foot checkmate twin 800 hp
 

I would say the boat should run in the high 90's with 1600 HP. I hope you have hydraulic steering!

If your setup is good I think you'll be over 100. My old 30 was over 100 at 1300 hp.

Hi- considering picking up a 86 Enforcer 240 and would appreciate any comments you might have as to the boat's pluses and minuses- thanks- Doug- Maine
