Thanks Captain zzzzz, member 18646. I keep my boat during winter about 100 miles from where I live and I want to buy new spark plugs before I go there to put the boat in the water. Unfortunately I left all my owner's manuals and paper work with the boat. Thanks, the information you provided will enable me to buy plugs.
