My previous boat was an Ericson 2-30, which came with an Atomic 4 engine.
If your neighbor's boat originally had a gas engine, the tank has a filter
at the end of the pickup tube. Try removing the pickup tube and see whether
the filter is clogged. You can clean it with a solvent, or remove it
completely. Your primary and secondary filters are enough.
