Looking for some advice regarding our 2011 SeaRay Sundancer 280. At the end of the season last year, our engine began a surging like when cruising on plane, had it checked out this spring but our mechanics didn't find anything. In the water for a couple of weeks and it happens then goes into guardian mode. Found a bulletin for this engine existed before we purchased the boat and risers were completed. The computer was reflashed and we still had the issues and now 02 codes as well. Oxygen sensors replaced and all was well Fri and Saturday. This morning heading back to the slip, while cruising on plane it stopped us and put into guardian mode 2x with an overheating code. This happened last week and we thought it was related to the previous issues. Apparently it's a new issue. Any ideas what this might be? I know our mechanics are going to roll their eyes when they see me come in tomorrow morning!
