you can always gain 2-3 mph with different props.be sure to have your prop labbed for best mph gain!! BILL :p :p

I have a '99 259 w/454 magnum power. 4 blade Bravo 1-24 pitch wheel. Speedo says 72, g.p.s. says 68. We all know that we can't really rely on either of these numbers, but, let's not get into that. I just use the speedo for reference, if it is running slower than yesterday, I know I have a problem. But, unless your speedo is way off, something is wrong.
