I have mercruiser 260..old model, I think around 1980. Two weeks ago I saw milky stuff in the bilge and thought it was oil leak from engine. The oil was at "Full". Few days later I noticed the oil level has lowered to "Add more oil". For the last few days its still at the same level. It is not...
I recently bought this boat and the engine (Mercruiser MCM-260) starts right up and runs great on low RPMs. Whenever I goto high RPMs, after few minutes the engine starts stalling and start loosing power. It immediately runs ok if I pull the throtle down a little. Any idea what is causing it?
