2014 242 LS engine overheat/ting-ing noise

[MattEisener]

Last run of the year to run some Stabil through it, cruising along at 30mph when port engine RPMs slowed right down and Engine overheat code flashed on the screen. Pulled it out of the water and it is making an obvious ting-ing noise. Tried starboard and sounds normal. Any ideas what I could be into? TIA

Is the sound from the engine are or the pump? I’d check the jet pump area for any debris.

The engine slowing down is limp mode........overheat alarm = slow down the metal tinging out of water could be impeller making a little contact with pump housing. Like haknslash check for debris in impeller and check the pump pick up screen in the impeller housing for blockage..........is screen is clear you next step is to test the temp censor( they seem to cause many false heat alarms.

I carry a infra red thermo gauge just for such happenings. Its always nice to know if its an actual over heat or censor fault. Last I installed Temp gauges last spring and it nice to see an actual temp rise if pump is clogged long before alarm sounds and limp kicks in. A quick screen clean and on my way with no codes.

Out of the water, I can hear the ting noise a lot more from the ground than inside the boat.

Also check your impeller to wear ring gap.
