I have a 2001 90 HP Johnson on my Montauk. The spark
plugs used are Champion QL78YC. Can someone give the
correct gap? Thanks, Keith

You can find the recommended spark plug type and the recommended spark plug gap for just about all OMC and BRP motors through 2008 in the REFERENCE section. Please refer to
