DB2, Soooo you got a lot of nicks and scratches on ya! Well at 66 you probably call them "war wounds" eh?
I think Liar, (although his name may be questionable when it comes to believing him) is pretty close on a price.
If your lower unit is still in good condition, powerhead is clean, and runs a good compression test, "I" would ask for up to 500 bucks for it. Good luck my friend! Barleydog
