When did Merc start using big bearing gearcases on their 200 h.p. motors?

Also if anyone has the part # for the case I'd appreciate it. Thanks:thumbsup:

According to th Pro catalog. They show a different gear set fot the 97-up and serial OG438000-up with a different forward bearing than the 96-back. Hope this helps!:thumbsup:
