Re: 470 starter
You may have seen this discussed
here. dn and stonyloam seem to have good luck out of those starters. I put one on my 470 as well but haven't had much chance to test it out other than cranking on the ground. It turns it over pretty darn fast.. and it shows they are made for Mercruiser.
Plenty of places sell those starters, but last time I was looking around, a lot of places had them on backorder (even locally). There is
a seller on ebay that sells them at a good price, but
ArmatureServiceCo sells them for the cheapest I could find, if he has them in stock. The part number is: 2-2591-DR-2.
Not sure if that is the exact one you are thinking of, but might get you in the right direction.
