> Aside from the clearance benefit, have any of you made such a change or know of the results of a smaller prop with the same pitch?
Yes. Long ago one of my Sterbas was cut down from 54" to 52" and in fact this was done with the same size engine you reference. The result was an additional 100 RPM. You might send that prop back to be refinished. Just suggesting this is an option - that crack doesn't automatically trash the prop. I had some small cracks on the tips of a well-used Sterba which he repaired and refinished (for free!) and did not take any diameter off of the prop. It looks like new and it's 25 years old. Cracks can be repaired. Mike KSEE ____________________________________________________________ Get Free Email with Video Mail & Video Chat! http://www.juno.com/freeemail?refcd=JUTAGOUT1FREM0210
