  3. Re: Mariner 90hp 3 cylinder 2 stroke 2004 - Bogging Driving Me Crazy

  8. Re: 1992 Mariner 40 Magnum. Starting and Running issues

    You are probably correct with " diameter. Mercury uses a special zip tie. Not your average bread and butter tie. Looking closely at it it has a curve on the inside of the locking ring. That...
  9. Re: 1992 Mariner 40 Magnum. Starting and Running issues

    Re: Hotter spark plugs for 9.9 4-stroke?
