    4.3L MPI 2007 Searay Sport 185. Single Alarm at 20 RPMs and higher

    Don't pay any attention to those codes, not part of your motor 2000 RPM with alarm, sounds like the In-Gear switch. Disconnect the switch on the shift plate and take it for a ride to see if it's gone. The Bravo drive has only the one switch

    Might be ok With key ON and motor not running, there is no oil pressure and ALT is not working. Oil and ALT light would be ON along with beeper. Once motor starts, oil pressure comes up and ALT starts working and everything turns OFF
