Will a complete Gen II drive work on any transom shield? Would this be able to bolt right onto an older gimbal housing(transom shield). I have one for sale, and people ask me if it will work on their older style engines. I know you cant interchange the upper and lower units, just didnt know about the complete drive. PLease someone help me out. Thanks in advance. Email me at standard@duo-county.com if you got any advice for me. Thanks again.
