Rpm and propellers

anytec522 · 08-15-09, 02:41 PM

I hope that you experienced boaters can help me with my question, even though it has more to do with engines than fishing. I have a propeller on my Yamaha F 100 2008 that allows the enginge to reach 5600 RPM at WOT. According to the engine manual, WOT should give rpm between 5000 - 6000 rpm. As I understand it, this is just perfect, since I have 5600 rpm at WOT, and the engine gives it´s maximum horsepower at 5500 rpm. Now, an expert told me that I need to change prop to one that will increase rpm at WOT to at least 5800-6000. My question: Do I really have to change prop for 200-300 rpm, when I am in the correct zone already? All of you who have knowledge in these matters, pls find time to answer, since I am becoming more and more uncertain about the whole issue.
