This is a call to all those out there running 25' Checkmates. Since thats what I have I wondered what kind of speeds everyone was getting. Also, what mods have you done?

GameOver, I have a 89 251. Last season I ran a stock and very worn out HP500. Best speed was 75.2 on GPS@5150 with a labbed Hydromotive 4blade 26 pitch.

This season I"ll have a fresh new HP500. Im hoping for 78-80 this year.

1997 253 convincor-525sc mercruiser-76 on g.p.s.
82 on factory quicksilver speedo.

'97 253 468 (575hp). ran 79.9 on GPS last summer.....this was on two different occasions/two different GPS's....just can't break that 80 mark . i just sent my Prop out to Bronson Hill to lab - 26 4 blade hydro. Hopefully i'll break 80 this season.

Dave, I have an almost identical setup
'96 251 w/7.4 pushing 310/330 hp @ 65 speedo so I'm assuming 60-ish

to top it of I'm in the midst upgraded to 500 hp also! keep me informed on how she runs.

oh, and what kind of prop are you going to be using Dave?

99 259 7.4 385HP 67 ON GPS 74 ON SPEEDO 3 BLADE MIRAGE PLUS 23P I THINK THE 251 AND 253 ARE NARROWER THAN 259??? ANY ONE TELL ME TYHE DIFFERENCES IN THESE BOATS. SEEMS TO ME THE 251 ARE THE FASTEST HULLS WITH HP BEING EQUAL??

I have a 98Convincor 253 came stock with 310hp & ran 60-61. with 21 mirage.Upgrade to 502 crate motor & 22 Hydromtive only got me to 65@ 5000rpm.Now added 226/234 duratiion 590/608 lift cam,Canfield alum heads & Team G intake and run 75.3 on GPS with a 26 hydromotive.With 26 bravo prop I can barely run 70.Hydromtive is definately the way to go with this hull!!

Game over ,
Im using a 14 .125 By 23 Turbo that I kept from the last boat I had .The boat came with A 21 Mirage witch worked ok but the turbo had better top end.
