Hello my first post here hope you cna help me on what to do. <br /><br />1996 Mariner 135. 2 stroke, with 130 hours. <br />The other day i was driving the boat as normal and it performed flawlessly. Whn i turned on the engine after shutting it down I it began beeping continuously whilst operating. I was a long way up river so i drove back to the pick up point the engine shut off once by itself. I waited ten minutes then drove at 1500 rpm back the temperature needle did not go above halfway. <br /><br />Is it likely that there is any damage to the engine what is the best course of action should i just replace the oil pump and assume the engine is ok<br /><br />thanks
