I assume, like myself, that most of you fisher people out there are confined to land due to the winds over the last 3 days so you might have some time to offer your opinion about what size of prop is best for a 19 ft. aluminum fishing vessel with an Evinrude 115 hp outboard. We fish all of Long Point Bay and the open lake as well as many smaller lakes. Is stainless steel a "nice to have" or a "no brainer"?
