Camano 31 propeller size, etc.
My 2005 Camano came with what I'm guessing is the original prop, 4 blade 20"x18", very good but slightly below perfect leading edge condition, no cupping visible to my eye. It works well, and my peak WOT RPM (10 minutes near the end of longer runs) is 3800 with pretty full water and fuel and prop-coated, which I think is 100 below spec WOT for the TAMD41 P-A of 3900. I'm very satisfied with that.
But, I wonder if any Camano 31 owners (especially with TAMD41 P-A equiped Troll models, which I guess is 80% of us) have used a different size prop, or re-pitched. Has anyone experimented with cupped props or something other than 4 blades? Performance outcomes? Thoughts on best brands, best values? I'm planning to use the original for a spare, have it rehabilitated, buy a new prop.
Do most folks use prop-coat or another anti-fouling paint on their props and bow thrusters? (My bow thruster was awful after 18 months, while hull was close to barnacle-free last year....brackish water. Double coated with prop-coat April 2018....we'll see how that worked this summer. What works best?
I truly appreciate all the great suggestions I read on TF, including solutions to problems I don't even have (yet....you know what's coming if I don't say "yet".....).
