Took the boat out Saturday morning. Goes in to limp mode. Threw the codes in the picture. Can cycle the key and it will run fine. Seems like the motor has a little bit more vibration at lower rpm than usual. I pulled the throttle body sensor and unhooked batteries and it ran for probably 30 minutes before it thru the same codes again. Anyone experienced this? Tia

Pretty sure its an injector failure on #5. Tell me how I know. Catalytic convertor plus aluminum exhaust manifold = bad news. Fighting VP on a major issue around this. Have you ever had other issues like exhaust overheat or O2 sensor failures? To be certain you may want a VP mechanic put a Vodia on it. The EVC does not always report all the issues.
