Re: [OMC-Boats] Marine Fuel Additives, Gas System Treatments and Ethanol E10.

Makes one SERIOUSLY wonder if the various rebuilders of marine-rated
carbs and kits are ALL using Viton or Ethanol-resistant seals, o-rings
and seats?

This fuel-related issue is certainly a lot more relevant than the
worries many had over Valve seat recession when Ethyl lead was removed
from gasoline.

Also, another great article EVERYONE should READ "WHY BOATS CATCH ON
