[stunod]

Hello again,<br /><br />I have a 15x17 which I just bought and WOT is 5100 when the manual says...3800-4200<br /><br />QUESTION: If 200 rpms on avg is per inch, then do I go up to 21???<br /><br />Thanks,<br />Lou

With a real lite load, prop about 200 rpm over so that when you load up, your in the envelope.
