if i were yo i would definitely do a google search and find some boat shops in your area and see what they would give you for them.

I found an old mercruiser inboard boat motor complete about a year ago while cleaning out an old barn for a lady and was going to scrap it as the motor was locked up and i thought it was junk but my buddy told me to call the boat shop he works with just to see and they offered me $250 just for the parts they could salvage off it (carbs, prop and few misc pieces) and i still has the block and everything they did not want for scrap weight.



definitely call a boat shop you'll probably be pleasantly surprised what even old tore up parts can be worth as others have stated above if they can repair and resell it it is worth way more than scrap weight.
