    Does anyone happen to know what the torque specs are for a 2004 115hp Mercury Optimax?

    Thanks in advance,

    Brian

    ps. those plugs sure cost a pretty penny

    Look on the spark plug box. If it has the compression ring you screw it in until the ring hits and then another 3/4 turn or so (it’ll be on the box). Side note, only go an additional 1/4 turn if the plugs have been installed before.
