Just as an update. Replaced both fuel modules, lucky to get them. Salt water had blocked water flow and when we dumped water from pump housing you could see and smell it’d been there awhile..of course bay testing boat and port engine starts up..apparently had water in bellows, no crack or hole in bellows, and it had been replaced 3 yrs ago...froze gimbal bearing. All replaced. Pulled drive for winter and no water in bellows...looking for 2021
