    What should the voltage at the battery read when the outboard is running from idle to max rpm?
    Thanks!

    Anytime the engine is running it should be 13.8 - 14.3vdc

    Actually- this engine may read significantly higher. Technically 14.8 VDC, but I have seen momentary blips as high as 15.1 VDC (without engine Guardian).

    This engine utilizes a stator and regulator system.

    It's reading 14.2 VDC at idle. 5 minutes after start up. Kinda hard to check it going down the lake. Lol. Thanks for the help.
