Bronze propellers will absorb a lot of shock from a propeller strike. Stainless propeller would be a different story but rarely see that on recreational boats.
I was able to program my MMSI into the ICOM 500 I purchased last year. I did get the MMSI through BOATUS. I’ll regret that because I do plan on going foreign one day. I guess I’ll have to send it back to the factory to get it reprogrammed when I get a FCC license.
