Message: <blockquote data-quote="tasthree" data-source="post: 489397" data-attributes="member: 23055"><p>wmkooo2: I do not have a exact load and condition comparison with this SRA3 prop and the factory Yamaha 11 1/4 alum prop. With 200 lbs of sand to mimic my wife and our dog the 11 1/4 alum prop did 5140 rpms. Different time of year, different lake, elevation and load the SRA3 prop did 5660 rpms. I did run the Yamaha 10 pitch alum prop the same day as the SRA3 and got about 5850 rpms with it. So same day, same lake and load the SRA3 was about 200 rpms lower than the alum 10 pitch. With this little motor and my boat getting the rpms about 6100 rpms wot is my goal. The rpms are perfect with the alum 10 pitch by myself. Add my wife, our dog I get about 5900 rpms WOT but with some current and or a little wind it bogs down to about 5600. I don't know how to link it but I did an extensive write up on another thread I did about this problem I'm having. I have massaged the alum 10 pitch a little and got a few more rpms out of it but still not what I want.</p></blockquote><p></p>
