JT the normal Bulldogs are 502's 470Hp. Whats done to yours?

No, no, no,
HP500's are 502 c/i
HP500 bulldogs are 540 c/i
both are "rated" at 470 prop shaft hp.
500 EFI's are "rated" at 470 too.

But, yet they weight handicap the
F-1, and F-2 boats that use the EFI's
over HP500's, so are they really the
same output ??????
