I have a 89' XP 150 recently replaced impeller and t-stats, boat ran fine first time out. Ran again this past weekend and while ideling away from ramp horn sounded even though motor was peeing ??? I unpluged the brown wire to the temp sender and reconnected and horn went off, could sender be bad??? or should I look elsewhere.
