I have replaced hi pressure pump as boat was stalling, full of the usual black paint I hear of about Volvo.
cleaned out the entire fuel cell and boat now runs fine BUT, at about 3000 rpm, only under load, I can hear a whining, but only with the engine lid open.Seems to go fine but I'm concerned something is being damaged.
Could it be the lo pressure pump ?
Replaced filter and fuel seems to flow fine to fuel pressure regulator.
