The Generator on my new to me 2021 Cutwater 30 CB has 11 hours on it. Last week the Onan generator would shut down after 30 minutes and generate code 53. Water flows easily into the sea strainer and when I put soap in the sea strainer bubbles appeared around the exhaust area in the water almost instantly after I started the generator. I looked at the impeller and it looks like new. The heat exchanger didn't contain any debris. Now after inspecting the impeller and heat exchanger the generator shuts down after a few minutes. I suppose inspecting the Exhaust temperature sensor is the next thing to do? Does jumping the sensor by connecting the leads to confirm it's the sensor? How do I access the area?
