Just bought a 2005 220 select bowrider, with 350 Magnum bravo three, only 260 hours. Been running fine, no problem until other day when alarm went off and said fault oil pressure on Smart Craft display. The analog gauge showed about 55-60 psi. Alarm would come and go and only sound briefly each time. Seemed to happen when on plane, but not while idling. Engine did not go into guardian mode and seemed to be running fine, even when alarm sounded. Any ideas on the most likely fault. Thanks in advance
