Call you post the serial number of the engine and I can look it up for you. The boat the engines are in is basically meaningless, we need to know about the engine, not the boat. here

Even with an hydraulic helm system, the engine will still have a power assisted steering, and it's associated cooler. The photos are of the front of the engine, the cooler is at the rear. The plug you're removing is the digital temperature input to the ECU. The alarm you're hearing is not an overheat, it's the ECU telling you it has no signal from the temperature sensor.

The pressure sensor is located on the power steering cooler as Chris mentioned. If you do not have regular PS but have hydraulic steering, the cooler is replaced with a brass tube. The tube or cooler is on the back of the engine and the sensor is screwed into it. See item 39

I need help to find the water pressure sensor on the star board engine. It is not in the location shown for sensors on the internet. I think it might be on the power steering cooler but unable to find the cooler either. Can you attach a pic. The boat is a 2009 290 SLX1253 SeaRay with twin T-350 Mag engines.

Yes and no about normal codes. Depending on your 8.1 app. Do you have smartcraft gauges - do have DTS - do have a catalyst 496 . Would need to know serial numbers of your motors to determine what you have as far as the 8.1. I will say this again and again anytime you take your boat in for service or buy parts from a OEM dealer the first thing they need to know is what is the serial # of the engines. Why because a 2001 496 is totally different set up than a 2010 496. Serial number breaks determine as were parts have change and different setups of that same engine. This holds true for all marine engines.

R U saying just an Overspeed code ? the jist

[nikitakit]

CODE 179 Starboard EMCT - is Starboard exhaust manifold temperature HIGH. Could be sensor or a cooling problem.
