Do you have the part # of the gear set that you're looking to buy ?

New genuine mercruiser 43-815662a3 *bravo 1 ,2,3 sterndrive upper gear set.

An 0M serial number uses the new style thick-floor gears. 0L and down uses the old style (unless it has been updated with kit Jaay Teee described).

815662A3 is an early style gear set with the thin floors, not what you want.

Thanks
There on ebay if someone can use them. Says they are new 200 $

In my opinion, They are not worth $200....
