Need confidence in my diesel
Have a Sabre 34 with a Westerbeke 27. Over the winter, had the fuel tank cleaned and fuel polished (obviously was having problems last fall). Went out this weekend and engine kept dying underway. Changed Racor filter and it looked pretty bad and got a bit of sediment off the bottom drain of the filter bowl. Bled engine and it would start but kept quitting within minutes. Kept changing filters and the filters didn't look too bad. Engine kept quitting. Finally today, I realized that I hadn't changed the O-ring on the t-handle. Perhaps it was pinched and drawing air into the system while running leading to the shutdowns? Engine runs better in idle than when trying to take a load. Anyway, changed the o-ring this afternoon and ran the boat in the slip at 1500 rpm with transmission in forward and at about 1350 rpm in reverse for about 20 minutes. Engine ran fine. Could the engine have been drawing air in through the filter? Filters still look very clean, so I'm starting to think it is not a problem with the fuel.
Advice welcome, confirmation if I am on the right track eagerly sought!
