Interesting point about the proper flow to make the water separator work. I
wonder if this on is in the proper range at about 1 gallon per hour.

Is it original with the boat ?
If so it was most likely properly sized by the engine mfg and builder
I'd suspect.
Is it trapping any water?

Joe

I don't think it's original and I've never seen any water. What I need is
to find instructions or specs for one of these filters. I tried Google but,
no luck.

Bought by parker, but I would imagine they have old flow charts
around, drop a dime.

If you use any of the standard fuel treatments, and if they work, you
shouldn't see water, as they all contain emulsifiers.

You are over-obsessing; forget all filters, go sailing.

Isn't that what this group is for?

Our yard put in the 500 for our similar engine. Remember that you
probably have more fuel flowing than what you're burning, most of it
circulating back to the tank.

If we didn't have that circulation, we'd *really* have a critter
problem, as we burn only about a third of a gallon per hour, about 10
gallons a year.

An interesting thing about the Yanmar 2QM series is that there is no return
line back to the tank. Evidently, the injector bypass just circulates back
as far as the injector pump on the engine. It is an unusually cool running
engine for a diesel so maybe that helps avoid the fuel getting too hot.
Flow through the filter is whatever fuel consumption is.
Just out of curiosity, I'm going to look at recommended flow rates on some
separator filters but I'll be surprised if any
go as low as 1 gph. It's appears to be a centrifugal process judging by the
spiral grooves I see on some of the filter housings so it must take a
reasonable flow. Just out of curiosity, I'm going to look at recommended
flow rates on some separator filters but I'll be surprised if any go that
low.

Chris had a good point, now that I'm putting an emulsifier
(StarTron/Soltron) in the fuel, The water isn't going to separate out
anyway.

Hmm, no minumum flow rates indicated on the Racor site specifications page
for water separator filters.

I found info on the larger units Roger, but I feel you are going to
have to call Parker/Racor and ask an application engineer for the info
on the older systems.
I'd be interested myself to the flow ratings on the old 2000 filter
housings.

The example below illustrates how part numbers are constructed.
1000MA M P 2
Specify Model
(see chart below):
500MA1
900MA2
1000MA2
75500MAX1
75900MAX3
751000MAX3
731000MA4
771000MA5
791000MAV4
Add M for a metal bowl
instead of the standard
see--thru polymer bowl.
(Omit if not desired)
Add P for a water
sensor probe6
(Omit if not desired)
Add a micron rating:
2, 10, or 30
(The smaller the
number in micron rating,
the more contaminates
the filter will take out of
the fuel. A 2 micron
filter will take out more
contaminates than a 10
micron filter will.)
Standard fuel ports a 1 3/4"--16 UNF (SAE J1926), 2 7/8"--14 UNF
