I replaced my old, chipped two blade with an Indigo 3 blade. Did not recognize an improvement. Furthermore, after light use over one season the three blade was evenly pitted on both leading and trailing edges, more pronounced on the trailing edge. I suspect serious cavitation. I think the prop is too close to the deadwood. Deadwood is 3" thick, Indigo blade is 4" long beyond a 1 inch shaft. 1 inch of the available 4 is directly behind the deadwood. My choices are:
1- Move the three blade aft by cutting the shaft and adding a spacer at the transmission, or...
2- Purchase a new two blade.
I want motoring performance above everything else.
What are your thoughts?
