I'm running a 30' Convincor with a twin turbo 572 making about 1300hp. Using a dry-sump #6 with a super cyborg tranny. Boat will run in the triple digits. Currently using a 28 4 blade or a 27 3 blade with a 1.24:1 gear ratio. Tranny is mounted in an extension box so motor is mounted in a stock bravo location.

1300HP! Drool...

Looks like you get the oscar for the fastest Checkmate on O.S.O. Do you have any pictures of the motors you can post??? I would love to see the engineering needed to do all the work with twin turbos. How did it all fit?

MY 2001 ZT240 WITH THE 496HO AND 25 MIRAGE PLUS RAN 73 ON GPS LAST YEAR. SPEED-O- WAS SHOWING 82 (I WISH).
ONLY HAVE 37 HOURS SO FAR AND HEARD THE CPU HAS A REV LIMIT TABLE (AZ SPEED & MARINE) PROGRAM FOR BRAEK-IN BUT THEY DID NOT SAY FOR HOW LONG. IT NOW PULLS HARD UP TO 4800rpms THEN NOTHING MORE. I'M WAITING FOR THE 40 HOUR MARK TO SEE IF ANYTHING CHANGES.
ANY OF YOU BOAT AROUND HARDY DAM ON THE MUSKEGON RIVER ?
CAN'T WAIT FOR GOOD WEATHER !!!!!!!!!:D

Hey, pretty new to the board, i think this will be my third post. I've got a 25 convincor, runs 75-76 any day, has ben clocked at 77.2 mph, FASSSTTTT for a 500hp. The boat has twin throttle set up, All Gaffrig Gauges on both driver and throttle side, full hydrolic steering,compcom communication for 3 peole, mercury 280 k-planes, motor is fresh from Innovation marine, has 5 fresh water hours on it. Great for Poker runs. cd changer, head in cabin,,,,,Oh yeah,,,,,,,,,did i mention i was for sale?
Sorry to be running a little ad here, but they are good boats,just don't have time for this one. the boat has been sitting in my company warehouse for almost 2 years, its too nice to sit!! The factory 2 race boat keeps us busy enough. if anyone boats ner the Chain o Lakes, im sure they've seen it,,,,,,,its an AWESOME boat. ,,,,,,,,,but so are all Checks.
If any ones interested, call Jim Porter at (630) 543-8145.

Haven't seen many posts from the smaller Checkmates.

My 92 Persuader 219 runs 62 mph on a new Magellan Meridian Gold GPS. Oddly, the speedo is exactly on the money! :eek

4850 rpm with unknown 22" round ear prop. Only marking is M-22 cast into the belled hub. Tried 23" Mirage Plus but bowlift was lacking and holeshot sucked. 63 mph @ 4600 rpm though. And a Merc 23" chopper that was worse: 57 mph @ 4900 rpm.

Going to pop some 1.6 rockers in and dial in the Q-jet and timing some more and see what happens.

Love my boat. Sooo responsive to trim, not like the Baja's. I run even with a 2001 7.4 310 hp Hammer with my small block. :D

We run a 229 with a big block 450hp. You may want to try a 22 Hydromotive I run 24 Hydro. The 4 blade made the boat much more stable at speeds over 70. I lost a couple MPH top end from the 23 Mirage but it's much easier to run at top end now. I had a bad chine walk problem with the Mirage, scary. Your 219 is a nice looking boat Checkmates sure age well. I'll put mine up against any boat 10 years younger.

2002 Pulse 210 w/ Mercury 225 efi 24" Trophy Plus 4 Blade. 73.5 mph GPS and 77 on the Speedo at 5800 rpm.
