Re: mercruiser gimbal housing identification
While I can't answer your Question,...........
I Can tell you that Any Mercruiser transom assembley Up to 1982 Should fit Just Fine,.........
There Maybe some Up-dates,... But it's Usually a Pretty Easy Up-grade Fitment.........
Even going to an Alpha transom assembley is Reasonably Easy,...........
But you'd have Other fitment Issues doing That........
