The QL82YC is the wrong plug. It has an extended nose on it that could hit the piston.

The correct plug is a QL77JC4 or the QL82C. The QL82C works great on older motors as it does not foul as easily, which was a problem with QL77JC4 plugs.

i went to ngk in my 18hp and 25hp johnson's and it made a big difference in start up(pull start). should i go ngks in the 1990 90hp vro?
