om...
Ive got a 2 cylinder 25 horse(johnson/evenrude) two stroke outboard.
The plug that was in it an L77J4 the book calls for a QL82C the
autoparts store sold me 2 QL82YC. Which is the right plug thanks Mike


The store gave you the wrong plug, The QL82YC is an extended nose plug and
is not designed for your 25. The QL82C is the factory recommended plug for
your motor, but you can use the QL77JC4 also, but it may foul a bit sooner.
OMC back around '95 revised many of their plug recommendations, so some
manuals may show only the old plug numbers in them.
