I cleaned and decreased mine with paper towels and then used dawn dish detergent to get the last grease out before sending to PYI.
I am on my 14th season and after discussing my prop condition with PYI, he recommended greasing every year. He also said that coming to neutral, hesitating, then going into reverse will avoid some wear. My prop wasn't terrible, but needed work. Put it back on last week, repitched to 20 degrees and went motoring for a short while. It was set at 22 degrees for 14 years and I am not satisfied with the 20 degree setting so am going to experiment
one more weekend and then make the decision whether to pull and change the pitch
back to 22 degrees. I picked up from 3400 to 3600 RPM
WOT but my speed didn't increase as I had expected it to do. I didn't get a true test as there was some current
so Labor Day weekend I will find some calm water
in a long cove and do some RPM/Speed test to confirm what to do.
