    2020 300 Pro XS Fault Code

    Serial number 2B738765 2020 300 Pro XS with 9 hours on it is giving fault Code 103-16. Says Ignition Coil is not working properly. Very frustrated being the engine has on 9 hours on it. Is this an issue anyone has run into yet with these engines??

    Maybe.... but falls under the "I'd have to see it to come to that conclusion" category.

    Update-- After a month long backorder for Mercury to get the part, the problem has been resolved by replacing the faulty injector.
