    I realize prop selection is a bit of a black art but wanted to get advice on a starting point... I am looking for a prop that will give me about 80% of max speed with a 30HP etec Evinrude. The boat is a Dux tunnel hull inflatable 13' loaded it is around 800lb. Would a round ear or cleaver be more appropriate? and what pitch & diameter would you suggest? my guess so far is this one : 14&1/4X19 round ear, am I even close? I will be using this in the bay which can get a choppy on occasion but not on big ocean swells. Any Recommendations thoughts would be appreciated!
