26' scarab Speed With 502
#2
I had one and it did 62 with stock 502.... I then removed the fuel injection put on a holley 830cfm carb with edlebrock victor jr. intake and stainless marine exhaust and the boat ran 68.
#3
Same as Tricky, 62-63 (gps) and with the addition of Stainless Marine exhaust and bumping the rev limiter in the ecm up I was able to get 64-65.
With the addition of a 540 I'm able to get 81 !
