I was just currious what is the rpm range at WOT in a 76 115hp, it has a 17 pitch prop

Re: rpm range

It should be 5000 - 5500 RPM's<br /><br />Craig<br /><br /> http://www.myfishingpictures.com/showphoto.php?photo=13003&sort=7&thecat=500&password=

Re: rpm range

Seloc says 4800-5300. Not sure how that prop size will effect it if any at all.

Re: rpm range

17 prop will have a GREAT difference in the rpm's you see at WOT especially if the prop you are using now has blades that are cupped. A prop with cupped blades will increase the torque on your engine and decrease the rpm's you might expect to see at WOT. If the prop you are using (the 17) was not the prop spec'd for that engine, you will NEVER see 5000 + rpm's!
