Hi all: We finished our conversion and took it out for it maiden voyage. It is a 14' old run of the mill fiberglass fishing boat that has been converted to a small flats boat. It ran beautifully in the water! (Pics will be forthcoming in the boat restoration section.) Beautiful running little boat! The tach is showing 7k rpm (tach was set at 4Pole during install)at WOT and I know this is too high.<br /><br />A little history on the motor: It is an '03 25EL Merc. It was used previously on a pontoon. The original aluminum prop has 13P stamped on it (assuming 13 pitch) and the radius from center of hub to tip of blade is 5" (10" diameter). I know I cannot go any larger on the diameter (the blades are close to the motor now). Any suggestion on what I try next?<br /><br />I also noted that the anticav plate is two inches below the hull. We will move it up an inch; however, from reading previous posts, we may gain even more rpm. Looking forward to the answers from you wizards!
