Thanks - that would be appreciated. This part is for an old aluminium Starcraft "Holiday" circa late 60's with a 120 I/O I'm in the process of refurbishing. Needless to say I'm reluctant to spend big dollars on such an old boat. You present as someone who knows his way around these particular model Mercruiser I/O. The lower unit on this sterndrive is VERY banged up, and if I could find a cosmetically better looking lower unit (complete or just a housing) I'd replace it. If on the off-chance you have or know of someone selling such a unit I'd be interested in purchasing it. I find this forum very helpful, full of many technically competent people with a vast network of contacts, connections, skill and product knowledge. Your willingness to help me with my problems is really much appreciated.
