Hello fellow sailors
Thx to the internet I get tips advices and help on how to trouble shoot and fix problems
This time I have a new problem with my 1968 perkins 4.236 85 bhp engine in my cal 46 sailboat, Lahlia which hails at Marina del Rey CA
I seem to remember that I was able to rev my engine passed 1500 rpm before
Recently it'd only go to 1000, achieving only 5 knots. Most of the time the engine starts right away, (requiring rebleeding at times) No black or white smoke. It runs smoothly. No water in the oil. It's not burning oil, no funny vibrations. Sounds great according to visitor engineer. Engines feels smooth and doesn't get hot fast
It has 1100 hours ( almost new)
Yesterday I had replaced my secondary fuel filter fearing ( on someone's suggestion) that I had reversed the O ring placement on the engine-attached fuel filter.... That was okay
But I did discovered that the O ring on the primary Racor 500 had been TWISTED. After this rectifying this and After bleeding the engine, I ran the engine to 180 F temp and I was able to reach 1500 under no load ( while at dock)
My stainless steel fuel tanks have been cleaned 5 years ago. The auxiliary
Electric fuel filter is clear and the fuel looks sparking clean coming out of the Racor before it feeds into the engine
When I ran my auxiliary fuel pump it puts out fuel readily indicating there is no impediment
Or obstruction to the flow from the hoses and fuel tanks, which contain biocides and stabilizers
Does anyone know why my RPM is not reaching maximum? And how can I rule out
Problems with injector pump or perhaps lift pump
Thanks in advance
