Time and again I have read that Yanmar does not recommend a 2/3 micron primary filter. I therefore use a 10 micron, and use Biobar, as well as some Seafoam. I have some old crud in my tank, but where I can see it through the hole for the sender, the bits I can see are pretty well stuck to the bottom of the tank (and there are not many of them). That said, the boat had sat at the dock for +/- 6 years before I got her, and we have run 150 gallons or so of fuel through the boat in the last 4 years. I change my Racor every year, and I used to change the one on the engine every year as well. This time, I'm going to let the engine mounted one go another year. We still get a fine layer of black "grit" at the bottom of the racor over the year, but it does not appear to hinder the running of the engine. I'd rather swap out a $20 filter once a year than risk the engine shutting down as I go through a bridge opening with 3 kts. of current.

I never wait for the engine to stall before changing and I do not have a guage. What I do have and maintain is a clean tank and use biobor religiously. I change my primary annually or before a big offshore trip, for peace of mind. Hell of a lot easier to use a 2 micron in the primary and leave the downstream 2 micron secondary engine mounted filter in place. I top off the primary Racor with Diesel when I put it back together so I never have to bleed.

When the Enterprise came down from New York, she was practically motoring the entire time, adding many hours of engine use in three weeks. For that trip, the filters were changed two times. For normal use, like Josh, I have a fine raycor filter and change that maybe once every several years - or if I can see notable clogging or the engine stalls. The filter on the engine Itself I change once every three years or so. I used to do oil changes and oil filter changes every fall before laying up for the winter. Since there is no real layup season down here in Florida, I still keep to my fall schedule. My engine (Beta 30) came with a maintenance schedule based on engine hours. If you have that for your engine, that should be an excellent guide. All the best, Edd———————————————-Edd M.
