    Inaccurate fuel gauge?

    Yes, this is the main problem. It's a shallow, below deck tank at the stern. It's pretty much impossible to set it up to read anything less than full until it's less than 3/4, and usually then only when off plane.

    170 MC, 1985 Seville, 21 foot Mid Cabin

    You may have had some water enter the cylinders through the exhaust and hydrolocked. That's very low...might try some thicker oil, but no magic. Where is the water? Mixed with the oil or in the bilge?

    I am not impressed with Carter at all. I went through 3 pumps last season. First one 9 psi, flooded carb. Second was 2.5 psi. 3rd was 3psi, and is still in there.
