I would inspect it closely, ground run it for the one hour engine break-in period, check it over again, retorque and fly it if it still looks OK. Flew mine for 8 years and 500 hours and it worked great. Very smooth on the 582. Changed to a PowerFin not because of anything wrong with the wood prop but I wanted a prop that would handle a bit of rain better. My plane was garaged in a climate controlled environment but if yours was stored indoors I would think it would be OK.
