Convincor 253 speeds
 

What kind of speeds are people getting with their 253 Convincors?

Re: Convincor 253 speeds
 

mine old boat was a 97 253. 570hp. ran 77 all day and in the best conditions 80.9 Gps.

Re: Convincor 253 speeds
 

Thanks. What is the dry weight of a 253 with a BB? 4200-4300? Sounds like the 8' beam slows them down a little?

Re: Convincor 253 speeds
 

I had a '98 454, 385hp did 60 ish. I put a procharged 502 and it went 78 on gps

Re: Convincor 253 speeds
 

What kind of hp with the 502?

Re: Convincor 253 speeds
 

Only two people in this forum have/had a 253? Anyone else out there?

Re: Convincor 253 speeds
 

I have a 94 253. It goes 59 mph :D
No boat, why are you looking for speeds for the 253?
If you do a search you can find a lot of different speeds listed. Before I bought mine, I rode in a few Bajas and Checkmates to compare. I thought both had benefits and ended up with the check.
The 253 hull will go 80mph with the right power combo, and still be driveable.
So i've heard :D
I think there may be insurance company trolls running thru this site right now, so I don't think many people are posting how fast there boat is unless it's an obvious offshore go-fast.

Re: Convincor 253 speeds
 

I'm looking for speeds because I am looking at a 253 right now. I'm just trying to get an idea of what kind of power it takes to run certain speeds. If I get the boat I would like to make it run 80-85.

SO, I will post my question differently. :D Does anyone know what kind of power it would take to run a 253 at 80-85? I'm guessing about 650hp?

Re: Convincor 253 speeds
 

650 hp sounds right. But at those speeds you are pushing that hull beyond it's abilities. @ 78 mph, mine was a handfull!! It would get squirley very quick in sloppy water.

Re: Convincor 253 speeds
 

Interesting. Were you running K-planes? Full hydraulic steering?

Thanks

Re: Convincor 253 speeds
 

I had a 1997 253 with over 1100hp. It ran a best of 104mph on GPS so I don't think 80-85 mph is beyond the capabilities of the hull. I did have full hydraulic steering and k-planes. The boat did require some "driving" to control chine walking but after 90 it settled down and just handled great.

Re: Convincor 253 speeds
 

Wow! 104 MPH! You've Got to be kidding! That's got to be the fastest 253 out there. who did you sell it to? CanDo

Re: Convincor 253 speeds
 

I took out the motor and put in a stock 502. I sold it to a fellow out east. The motor out of the 253 is now in my 30' Check.

for sh#@! and giggles, what did the size of the boat due to performance.
you added 4-6' of boat and plenty of weight, however i would guess you run twins right, did you build another?

Re: Convincor 253 speeds
 

check300: is running just the 1 motor with a #6. and it to runs in the 100+ club. very nice and clean looking. and the motor is so cool to look at. see you at hardy bill.

Re: Convincor 253 speeds
 

It is a very sweet setup, twin turbo engine and a #6 drive.

Re: Convincor 253 speeds
 

I reconfigured the engine with bigger turbos, different headers, and a new engine management system. The 30 is faster than the 253, because the engine is making a lot more power.

Re: Convincor 253 speeds
 

thats sweet, can you post some photos of boat and turbo setup?
maybe a new thread so i dont step on the 253 speed thread here!!

dont know the difference in hulls but my 242 runs 72-73 with about 550hp,
i would think it would compare though.

As I'm just a standard member right now, I can't post photos. There are some pictures on the Checkmate-boats forum. News and views Pg 12 of the thread about the 2005 regatta.

Check300 "Wild Bill" is one of the Gun lake ban of Crazy SOB's they can build chit that will really run! My 1994 253 with a 385 HP mag ran 63 on gps added a B&M 250 blower and pipes it ran 77 solid as a rock.
