Mike: Did you check the oil level after the alarm sounded? It could be low after a period of little use followed by motoring for a few hours. At higher RPM’s, the oil might fall below the pickup as more oil is pumped to the head than returns to the pan. I hope it is simple…..

Used 15W 40 Oil level checked July 22 300 mile delivery to Cape Breton (Dundee then Baddeck) July 23 – Aug 2 Yesterday after running engine at 2800 RPM for approx. 5.5 hrs a “clicking sound” was heard in cockpit. Thought at first was from Ram mic but was still there once disconnected. Determined was coming from alarm speaker on Yanmar panel. Tapped panel and then Oil pressure light illuminated and alarm sounded. Shut down engine and sailed to dock (without crashing) At dock started engine and at idle no alarm or light. Revved up to 3000 RPM and the light started flickering and a sputtering sound from the speaker (the clicking sound we heard earlier) which was followed by full illumination of Oil pressure light and full alarm siren. Stoped engine and waited. A few minutes later retarted engine and had no alarm at idle, followed by sputtering and then full alarm at high rpms. Reduced RPMs to idle and alarm stopped and light turned off. Any thoughts? Boat is currently 3.5 hrs away by car so any parts will have to be taken with me in advance _______________________________________________ Email address: CnC-List@cnc-list.com <mailto:CnC-List@cnc-list.com> To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com <http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com> Rich Knowles Nanaimo, BC INDIGO LF38 Boatless!
