New boat to me...2hrs of operation later on 1989 TAMD-41A with 450hrs. Engine was operating with 45-60 oil pressure. Alarm went off and noticed oil pressure on gauge was zero.
Shut down engine immediately and towed in. Verified both gauge and alarm were operating properly - no false alarm. Removed the oil pressure sender and started engine. Oil came out in spurts but not high pressure and smooth like a geared pump. Is it more like the problem is with the oil pump, oil pick-up to the pump, or possibly the oil filter relief valves. Or.....? Very depressing after perfect survey and sea trial.
