I have a lower unit and prop off of a 1996 Mercury 150efi. 20 shaft. Comes with a trophy prop, no markings on prop but guess its a 23p or 24p as it came off a 18.5 Skeeter. Nothing wrong with lower, removed to replace with a jet pump. Has hydrofoil installed. $500 firm for local pickup eastern NC. Can text pics send me message at 252-714-1430 if interested
