If the 115hp is a 60 degree motor, the correct plug is QL78YC. If it is a 90 degree motor, use the QL82C plug.<br /><br />The only correct plug chart for Johnson and Evinrudes is published each year in the J-E Genuine Parts and Accessories Catalog that every dealer gets.
is this true<br />From what I know if your tilt/trim switch is on the right of the cowling it's a 90 if it's on the left 60. looking from the back of the motor.<br /><br />I FOUND THIS MAY BE TRUE MAYBE NOT.
If you take the motor cover off, can you see the flywheel? If so, you have a 90 degree motor that takes QL82C.<br /><br />If you can't see a flywheel, then it's a 60 degree that uses QL78YC plugs.
