<DIV><FONT size=2>To give the rated horsepower... you have to under-prop and rev

power.</FONT></DIV>

drives to swing the bigger props at lower, more efficient RPM. But the

<DIV><FONT size=2>So we put on bigger props and operate the engines in a

<DIV style="FONT: 10pt arial">The prop choice is quite interesting. Curious
as to what kind of rpm it will turn the 17x13. A 2 stroke 140 easily turns
the 17x13 in a useful, quiet rpm range. But it's possibly a bit
fast. <BR><BR>It seems to me a bunch of people flocked to the 140 EFI
about 5 years ago, and maybe OS is thinking "loyal users". Fast forward 5
years with electrics making the strong showing they are and for good reason,
and the YS right there also for good reason. <BR>In my
view OS may have missed the boat on this one. If it will run a 20x11 at
7000, they may have something<BR><BR>MattK<BR><BR>----- Original Message
