Yes, that is the secondary filter, but not the one I'm having problems with.

Thanks for the feedback. I think you are referring to the secondary filter if you are referencing the one located on the engine and which has the water detection wiring. I'm referring to the off-the-engine primary filter between the fuel tank and the secondary filter. When you said you...

Ordinarily I'd do that, but because the primary fuel filter is separate from the engine, it is not necessarily associated with the 4JH3-TE. I think I need to know the part number for the filter assembly so I can identify the correct fuel filter. I was hoping someone here has the same filter...

Additional information - the notes written by the original owner many years ago say it takes a Yanmar fuel filter part # 4230-0100. Somewhere along the line a different replacement part was used. Not sure if the one that is there now is incompatible. Many thanks to Archie for the link to...

Pictures hopefully attached below.

I've now taken pictures, but it seems as if I cannot post them except from a website, but not from my laptop. Is that right? (Don't have a website where they are available.) Also, I realized I mis-spoke about the primary being a Racor. It is actually a Yanmar primary filter/water separator...

Will do that later this morning. Also, not having any luck looking up the filter housing online to see what part number it is.

The questions several of you have raised about the Racor primary have me thinking. I purchased a replacement filter of the same number as the existing Racor filter that was installed when I got the boat. But removing it was nearly impossible because it was on so tight and it required a level...

Weirdly, the Racor primary that I removed had a chamfered seal at the perimeter of the filter (it is the spin-on variety of filter). The replacement filter came with a much smaller diameter square edged seal that seats around the center post, but no new perimeter chamfered seal. So I used both...

Thanks. Will try running for a longer period. Fuel valve is definitely open.

I have a relatively new to me Yanmar 4JH3-TE on which I did the first fuel filter change yesterday. Now I have a couple of problems. The engine, which ordinarily fires instantly with no throttle, now needs large throttle input to start. and when it starts also won't hold a steady RPM and...

I agree with much of what has been written earlier about the better performance of the newest generation of anchors. My observations are as follows, based on anchoring out during uninterrupted months of sailing dometically and abroad: 1. Whenever another boat dragged anchor, I observed what...

Two of the best I've seen over many years: 'Higher Porpoise' and 'Good Grief'

One of the beauties of boating is that it mostly gets us away from the idiots who run government. Licensing would only give the 'authorities' an opportunity to tax, fine and regulate boating which does nothing to improve safety or the experiences we seek. It will do little to nothing to...

I'm mostly a traditionalist about boats (I have accepted fiberglass into my life however) but I think the foil racing in the AC is good for these reasons: 1. It's like watching Usain Bolt run the 100 - it's exciting to watch! 2. The old mono-hull races failed to excite the public, but the AC75...

I cannot say definitively what the differences are between the 335 and 425 HP engines are, but larger injectors are definitely necessary to deliver the extra fuel needed. There was also a model of those engines identified as 6-71 TIB, in which the "B" added a the blower bypass option. As...

I agree with all the above and would add that if you give her the wheel it will make her feel more in control as well as giving her a better sense of the boat's capabilities. This will build her confidence.

Back in the 1980s I had a Bertram 42' sport-fisherman with twin Detroit Diesel 6-71 TIs turning 36"x36" propellers. The engines were rated at 335 HP each (IIRC). The boat was a bit under powered with these engines due to its approximate 40,000# weight and deep V design that made it an...
