i have a 1993 253 convincor running a 502 with a blower shop 250 supercharger.. have not run it yet it will be close to 600 hp wondering what people are getting for a top speed if it chines... just lookng for a little feedback thanks let me know what your are running a for top end gps

Have a buddy that has a newer 259 (2000), HP500 and had a single carb blower on it. Ran 78 or so. He took the blower off due to drives being expensive to repair. He now runs around 73 without the blower. I think the older boats are heavy in the front compared to the newer ones. Hydraulic steering is a must and you will have to play with props to get the chine walk out of it. Either way you will have your hands full. Checkmate builds a great boat.
What drive do you have on it?

How much boost are you going to run?? Al

had a bravo one w/add on steering no k planes ... boat was in big fire a week ago.. gone sucks i was really hoping to hit 80 with it ... thanks for the imput though ..

Before and after... ****ty day..

Oh my god, does that suck!!!!!!!!!!!!!
Sorry of your bad luck.

man that sucks !!! was it insured ?

Friend of mine has a 253 with a 509 with a m1sc with 8 lbs and hits 80 all day long...no external steering at all....but hp numbers are more toward 700 hp.

brings a tear to my eye.

I owned a 2000 259 Convincor for 3yrs. It had a 502, Mooneyham blower, dual holley doubles, full MSD, Holley fuel pump, Marine Machine steering.....I was not at all impressed with it. Chine was horrible and the you could not keep it from porposing in even the lightest chop no matter how you trimmed it or tabbed it.

probably could have used a different prop. one with no bow lift at all.
