Use the following prop usage chart to match the proper prop to your boat and
engine. In many cases more than one prop is recommended. The 1st prop recom-
mended is the smallest followed by one or two larger props. The 1st prop recom-
mended is generally used for low nitro or where high R.P.M. is needed. It's
also great for breaking in new motors. The 2nd and 3rd props are for higher
nitro fuels (50% to 60%) or where a higher strut height is used.
