Hi,<br /><br />I have a Mercury 60EFI on a fiberglass runabout boat. The boat with 3 on board is approx 1300lbs. At the moment I have a 14 pitch standard 3 blade aluminum propeller. Top speed is very good, but it has a little trouble getting on the plane. Also, WOT is reached fine.<br /><br />I have the option of changing to a 4 blade prop, or a 3 blade prop with a larger surface area (both at a 13 pitch). Has anyone had any experience of this situation? I don't want to consider stainless because of the price.<br /><br />Thanks!!
