2000 donzi 377 scoprion, throttle needed for warm starts
#11
I have twin 350s, 2001, MEFI 3 as well.
I did new fuel pumps, coolers, and pressure regulators. Solved a lot of my similar issues. it's a hassle to get all that off in the hull, so I just did 'all the parts'. The pump would work when it wanted to, and the pressure regulator was all rusted up.

UPDATE: filled with fresh 93 and still have the same issue. 30 percent throttle to hot start. if you run boat and turn the boat off. it starts back up immediately and runs great. even after sitting for a few min. This is BOTH engines.
note, this has happened twice after boat sitting for about an hour and half each time.

Is it alcohol free fuel that you are putting in?

As a test Put a cold wet small towel on fuel filter separator when you turn them off.
