Your PSA for the day:
Check for fuel leaks regularly. These gen3 style cool fuel pumps from Mercruiser are known for developing fuel leaks from the areas surrounding the pump head and fuel pressure regulator. It is especially common in areas with higher ethanol content in the fuels.
When experienced, the pump module should be cleaned and resealed or replaced. If you find loose paint in your fuel pressure regulator you should remove your fuel injectors and have them serviced and flush the fuel lines as well.
Some common symptoms you may experience prior to a leak is poor idle quality despite fresh spark plugs and fuel or overall poor running conditions especially when accelerating to get on plane. A fuel pressure test would show an unusually high or bouncing fuel pressure readings with these conditions.
