I have a 2005 seadoo rxt 215 ic with 35 hours on it. Last week I went to use it and it would not start. It smelled of gas so I pulled the plugs. #3 cylinder was full of gas. I turned engine ove and flushed it out but it still pours gas in # 3. I replaced the injector and it still does the same thing. I brought it to seadoo for a budds check . No codes came up. The mechanic thinks the ecu is bad? 769 $ for unit and 4 hours labor programing and install. I was wondering if anyone has ever heard of this before. And if so how to fix it?
