Good diagnostics I came to the same conclusions. This is now my boat, purchased last January in this broken state. It’s now running well. Required a new long block i installed on starboard, one new injector on starboard it was leaking very badly hence that moisture you saw. It also needed a new fuel pump. On port it needed a new fuel pump and 110 gallons of phase seperated ethanol gasoline removed at substanial cost to dispose. All new fuel filters top and bottom and i suspect these will need changing monthly. Oh port engine also had a intermittent ignition control relay that made the fuel pump often not work even at key on 2 seconds
I hope that this helped. That boat was in exceptionally poor condition. Im glad you could get it up and running. we are a local crusader dealer if you ever need anything!
it was old fuel. No one in Long Beach would sell me aviation fuel. I filled the tank with StarTron fuel tank cleaner, let it soak for 2 weeks, came back and drained it all out and refilled with Premium Gas. The old fuel made a mess of the whole fuel system, not to mention I had to source new metal fuel lines since the previous owner replaced with rubber hoses and took away the schrader valve I needed to measure fuel pressure.
