Hi, Was running my 200HP 2 stroke at around 4200rpm when the alarm went off. Immediately stopped the engine and checked oil level, both tanks were full. Digital tach gauge showed no problem. Water was coming out of the "pee" hole and engine did not appear to be over heated. 5 minutes later turned key, engine fired straight up, no alarm. Motored back to marina, approx 30 minutes, 4000 rpm, no alarms, no apparent problems. Has anyone got any idea why the alarm went off, or what I should check. my thoughts would be a faulty sensor??? Thanks in advance, David
