Pics below is of the motor after it came out of the 242 and went into my cat. Sold the boat to some dude from OH in 2003. Bow-tie block, 9:1 JEs, custom Crane cam, AFR heads, Crower SS roller rockers, Whipple Inner-cooler, TBS 10-71, Nickerson carbs, and a whole lotta KE parts...

Believe it or not it was fairly stable. As stable goes for a 24ft boat at 110mph. The key was having full hydraulic steering and the delta pad bottom design. Once the boat rocked back on the pad it more or less just sat there. I know you won't believe it, but very little chine walk. The 242 Convincor is an awesome boat! Pic below was with first generation motor. The original 454 with a 177 blower. When I dropped the 540 I had to scoop the sunpad.

C112_ that is some awsome #s in a 24' Mate! Do you have any videos or pix?
What does your board name mean? A plane? |
I have a few other pics, but they have to be scanned. Owned the 242 before I got into digital pics. As for the name, after the Checkmate I owned a 28 Commander Cat that ran 112mph with same motor (though de-tuned with only 8lbs of boost, no NOS and pump gas). So I changed board name to Commander112.

my 89 251, no galley, with a 489, 177 blower @ 6-7 psi and a 26 bravo 1 ran 80.4, but did not have hyd steering(yes I know) only tested a few times, handling became a experiance to say the least ! and pulled the blower set-up for a n/a 509 which I put in end of the season...

Has anyone seen performance numbers for a 28' Convincor with twin HP500's?

I can spin that 25" P5X to 6100 rpm. That equates to about 12% slip @ 85 mph. Impressive considering I am running a -2 shorty. A long time ago, I ran a 26" B1 . At the time, I had a standard length Imco lower. I dont remember what rpm or speed I got out of that prop, but I do remember pulling the stick back because the engine was revving higher than I wanted. At this point, I dont know how or if my set up would run with a B1. All I know is that the P5X seems right for now. I can pull up on plane easily, turns great, jumps waves, what more can I ask for?
