propellor pitch for 25 seafari i/o
Can anyone tell me if I would benefit from a 4 blade prop, I currently run a mirage 19p 454cu in mercruiser i/o WOT 4350 rpm @39kts. I am primarily concearned about mid range cruise (25kts) and fuel economy. Any help would be greatly appreciated.

Perty bote in...deeeeeed
 The last time I bought a prop for the Seafari I was too busy crying over how much I payed for it to pay attention to the pitch  however I don't think I would be of much help anyway as I'm about 10 mph behind already Possibly more info is required but hopefully Fr. Frank might chime in. Brandon P.S Ken, PM sent re: hatch

Don't show strick these pictures!! 454 sounds like a good match for the boat. What kind of economy are you getting with the mirage 19p at cruise?

Re: propellor pitch for 25 seafari i/o
I like the Mirage, but some are getting better mid-range performance and economy wit 4 blades, but at the cost of a couple MPH in top end.
Rev 4, or 4B Trophy are worth a try. Better yet, contact the guys at PowerTech and ask about the OFS 4 blade.
