Have a pair of 2017 F50H's on my commercial fishing catamaran.
Recently both engines have started stalling at idle after an hour or two of running.
The nature of the boats work means the engines go through repeated cycles of cruising, then idling for 10-20 mins, then cruising again. They don't usually stall for the first hour or two. Pumping the fuel bulbs until they are rock hard, and then restarting solves the issue for another 30 mins or so, then it happens again.
The engines have separate fuel tanks, lines and external filters. I am pretty meticulous about filtering fuel.
The port engine has been doing it longer. It also had issues with bogging down at cruising revs, but I replaced the VST filter and had injectors serviced and that solved the issue. The port engine has also had a new lift pump. The starboard engine had been running perfectly until last week but now both engines are not keen on idling
Any ideas? Or if people need more info let me know. TIA
