How long does a propeller
last on a sailboat? 14 inch two (fixed) blade Martec, if it matters.
I'm sure there are many variables - damage, zinc replacement frequency...
But is a 14 year old prop apt to be mostly used up? I found a receipt dated 1997 in the ships papers.
When my boat was surveyed the surveyor
rapped on my prop with a piece of metal and said it "didn't make a ringing sound like it should." I talked to a prop shop since and they said when I haul out
(very soon) to bring it to them and they will sandblast and check it out, that no prop makes a ringing sound when on the shaft.
I'd like to change from a two bladed prop to a three bladed Campbell Sailer if it is time (or nearly time). I'd not like to be racking up boatyard fees
while I have one made and shipped, or racking up charges at a prop shop tinkering with a prop that is nearing end of life.
Even after aligning the engine
the boat has vibration I'm hoping the prop change would help with, but it's "on my list" mostly for the surveyor's concerns.
