There are no "generations" in the 496, but there have been updates all along. 2) The 8.2 was discontinued being offered to boaters long ago by Chevy, and Mercury Marine bought the tooling to make their version. Thus, I believe that Mercury does their casting of the 502 somewhat different than Chevy did. Merc Racing used both chevy's version of the 502 and their own at different times. Merc Racing offered 502 at various power ratings, from 500 Hp and up. 3) I hope this helps. 1) If you want to stay with pure Mercury Marine, they come in two Hp ratings and internal parts.

I'd prefer not to have a catalytic converter.. so, wouldn't really be interested in the 8.2. I'm thinking I should be considering the tried and true 8.1. Are ther Generations? or do you have a serial number range that correspondes to the date of manufacture? I know my '98 Merc 454 is a Gen VI and I can get parts accordindly, however I'm not up to speed with which Gen that I need to be looking for... when looking for a merc 496. Can you point me in the direction? Thanks Mark Hello:
