Which prop for 1994 Four Winns 278 with King Cobra 454?

New to this fourm,

Can any one tell what is the correct prop to use on the 278 with a King Cobre 454?

thanks

Until someone finds this thread who has the identical boat with that engine, do you have a current baseline (current prop, wot rpm, & performance goals for a new prop -- e.g. higher top end speed or too much or two little wot rpm, faster time to get on plane, better fuel economy, or ???)
