Re: OMC Military Outboard Motors
Are you in a state that requires titles for outboards? If not, the guy may well have thought he had what he told you the outboard was. Nothing wrong with a 1991 40hp model. In fact, in the long run, it's a better deal, since some parts for military models are impossible to get.
Still, it's 11 years older than stated. But it may not be the seller's fault. Lots of folks believe whatever they're told. Or, it could be a bogus deal.
Good luck, in either case.
