  • Yamaha F4 timing advance

    Hi!

    I do have a auxiliary F4 used mainely for *****ing fishing on a few times a year and get about 2/3 kts max but I need a little more speed for my fishing.

    If I advance timing 1 or 2 steps "teeth" do I will get a better perfomance and mantaine the reliability?

    Already opened the block and advanced 2 steps and motor/piston runs freely.


    I know most of you dont recomend motors mods but I would like to hear you anyway.
