This is a nice original example of the largest motor
Mercury built for the Western Auto Stores chain.
I purchased this motor in 1979 from a collector in
Maryland. It came with a packet that included the original
owners manual, price tag, bill of sale, and advertising
literature. It was bought new by a friend of the MD
collector. I did the necessary maintenance and first ran
it in 1995 and have used it occasionally at antique meets
since. I was fortunate to have this motor featured in the
book Beautiful Outboards by Peter Hunn.
