I have the F450HL Falcon Rider. I have the Evinrude E-tec 60hp. This engine is extremely powerful and I cannot use rpm over 4,000 without feeling way out of control. Even fully laden it still hauls. I'd recommend the E-tec 50hp. I tried to post a picture but it wouldn't work. Now that I have the E-tec 60hp I wish I'd gotten the F500HL
