I have a westerbeke 3 cylinder generator in a 97 400da. I just have had the boat for 7 years and just got it running last Friday after changing the cap, rotor, fuel separator and fuel pump. I also cleaned the carb but it was pretty much spotless. The generator starts right up and runs well with no load. If I add a small load it still runs well. I can add one AC and it runs but sounds like it is struggling and if I add the second it struggles even more with excess fuel smell coming from exhaust. When I first got it running it wasn't pumping water so I checked the raw water impeller and it looks like brand new. I pulled the hose off the heat exchanger and it immediately started flowing so I put it back on and got water flow. The next day I had to pull the hose off to get it to flow again and still have the same running issues. I suspect the heat exchanger needs cleaned and is causing the problem. Any advice on flushing without removing and does it sound like I'm on the right track
