    1998 merc 150. 2 litre 2 stroke

    in the middle of my rebuild, and saw in a mercury manual that you need to "Remove idle stabilizer/advance module, install idle stabilizer and reset timing.
    Refer to Service Bulletin 91-35." what is this module that needs to be removed and what does it exactly need to be replaced with?
