OK so i just purchased a 91 Avanti, today i took it out and ran into shallow water and actually got stuck....long story short i got loose but at the expensive of banging my prop to hell, fortuanetly the guy i got it from gave me a brand new extra one with the boat. I also banged up the part below the prop, searching the internet tells me this is called the "lower part" is there any way to replace the metal or does it require a whole new piece which im seeing goes for 1000 bucks? ANy help would be appreciated.
