Well, the fine folks at West Marine goofed and sent me the wrong rebuild kit for my 9.9. The jokers wouldn't refund my shipping costs for their mistake, but told me to not worry about sending this kit back to them for credit. (Lesson learned...moving on. ) Anyway, from what I was told this kit is actually for a Mercruiser Alpha 1 outdrive. Part # is 18-3217D, kit is brand new unopened and retails for $42.99 + shipping from West Marine. http://www.westmarine.com/webapp/wc...eId=10001&Ntk=Primary+Search&ddkey=SiteSearch *I will mention the picture isn't accurate as this kit doesn't contain the impeller housing as shown, but looks like everything else is there. Please don't ask me if this will work in your outdrive - I honestly couldn't know. You'll have to do your own legwork on the parts #. I'm just wanting to recoup my lost 2-day shipping fees. $20 OBO or trade...?
