Hello All,
Am looking for a prop for an O-200 engine.
Also, Jeff and Larry, you both have prop extensions on your O-200's. Why?
Do I need one as well? If so, anybody got one of those they don't need as
well?

I'm running a Sterba 60x68, supposedly re-pitched to 64. Wish I'd left
it at 68P but I'm only pulling 2800rpm, max cruise and couldn't really
tell the difference between the two pitches.
My prop extension is a Woofter / Saber (name is now just Woofter (sp) 5
inch extension. A prop extension will put the prop further out front of
the cowl and should make it more efficient. I assumed if the racer they
did climb record attempts / racing could use a 13 inch extension that a
5 inch should not be a problem. When I ordered mine I asked for a 4
inch but they had a 5 inch on the shelf for the same price. That was a
no brainier. It also gives my KR a shark nose appearance. If it's in
the budget I'd go with an extension. The Woofter (sp) extension is a
work of art. Not a sharp radius anywhere to prevent cracks. Even the
inside dimension changes are something to admire. The drive lug holes
are very snug to the point of using a rubber hammer (lightly) to remove.
