I have a 2018 Nitro Z19 with a 200 Pro XS. This past weekend the warning horn sounded at startup as usual the first time I cranked it, later in the day, the horn sounded weak. The in afternoon, no warning horn when cranking. Motor cranked fine, ran good. no issues other then horn not sounding at start up. Could this possible be the horn going bad or a loose connection, or possible some other issue.
