I have a 1993 18' Bayliner with Force 120. I hit something and took a decent chunk from one blade of my prop, wondering if I file blade edge smooth if it would be ok to run for a couple days on the lake until I get a new one? Dosent seem to have any noticeable vibration but im sure it has to be somewhat out of balance from the missing aluminum. Prop is aluminum 17" pitch. What do you think? Too big of chance damaging lower unit? Thanks!
