Alarms

[Comfortably numb 2]

Just started up the motor for the first time this season,all fluids have been replaced,the hose hooked up with good water pressure. The oil pressure is at 45 lbs at idle ,temp slowly climbed to 190* and held there for a few minutes then the alarm went off, heat Gun showed 190* at the t stat housing exhaust jackets at 200 to 210 Not a lot of water coming out of the water port on the port side of the outdrive, the sea water pump was replaced last year, ran cool last year at about 160*. Not sure why it’s running warmer than usual and the alarm going off
Any ideas??

Impeller probably needs to be replaced?

I'll check it out I have about 10 hours on the pump since I installed it

Also I’ve replaced the fuel pump three times in the last three years. Each year the pumps leaked gas into the seawater / fuel pump drive, original pump I replaced with a sierra,lasted one season, second pump was OME MERCRUISER
It lasted one season, now I put another OME pump I don’t know how the fuel is getting past the diaphragm or why. Any ideas ?
