I currently own a 1987 Baja 240 Sport with a 460 OMC Engine with King Cobra drive. I am trying to select the bet prop for this boat which will get me out of the hole fastest and hopefully provide me with the highest top-end speed available (hopefully there is a prop for such a combination). Any suggestions on how to figure out what prop would be best for my needs?

Not sure how much it will help.. But I have a 88 240 sport with merc 454 mag. Forget my drive ratio but I run a 23 pitch mirage prop. I also have a cleaver prop at, I believe, the same pitch. The mirage gets me out of the whole faster due to added surface area, but the cleaver is faster top end.

I have a 86 baja 25 mirage seems to work great.
I also had cleavers but i like the mirage much better. I think your best bet is try them all.

A Mirage Plus will be the prop that produces the greatest top end. Your drive is pretty deep and will perform best with a 3B. However if you are looking for performance than it is possible you may appreciate a Bravo I propeller.

If speed is your biggest concern, consider having a Mirage Plus Lab Finished. Make sure to get the correct spline adaptor
