Re: prop diameter
The diameter is a rather fixed factor. When you order a 19" pitch, there won't be any (or very few) choises.<br /><br />So, if your previous prop worked to your satisfaction go order another 19" for your motor.<br /><br />Stainless may be a good idea but should be considered in relation to the experience you have with the old prop.<br /><br />A good prop show will allow you to test run a couple to help you make the right decision.<br /><br />Do you know what rpm you had at wot with the 19" alu?<br /><br />Check "prop" link bottom of this page.
