This cosmetically
unrestored motor is one of the last "silver"
Mercury's. The "S" in the model number meant it was
equipped with a recoil starter. I purchased this
motor from a collector from NY in 1975. I did not get
around to getting it running until the year 2000.
After a small amount of running, it shuddered and
stopped. I found the crankshaft had broken! I
rebuilt it using another powerhead and the rebuild
first ran in 2006 and occasionally since.
