Re: YANMAR 4JH3-HTE Diesel Engine RPMs drop and then it quits
Ian Shepherd
Michael, I had a fuel starvation problem with my Yanmar, but it was in starting, not whilst it was running, though I seldom use the engine other than for leaving and arriving at the dock. It was due to air in the engine fuel filter housing. I had changed the engine fuel filter, and whilst all looked well after bleeding, the problem was traced to the O-ring at the bottom of the filter housing. Having change the O-ring and made sure that it was properly seated, I have not had a problem since. You might want to check this area also as from what I read, your mechanic had taken the engine fuel filter off. Regards Ian Shepherd SM2K 414 Crusader -Cyprus
