I just finished winterizing my 2002 1GM10 Yanmar Diesel (that runs on
a Menger 19' Cat boat) and think there must be a better way of
bleeding the fuel system. For the past three seasons I have changed
the water seperator and paper filter on the engine at the end of every
season. Then I begin the huge task of pumping the Raycor water
seperator for the next hour until fuel starts flowing into the engine.
After that I start pumping the lever on the oil pump (1 hour). Once I
get fuel into the lines the rest of the bleeding goes very easy. My
hand afterwards is sore and battered! I have tried cranking the engine
for short bursts with the compression lever up (this does not seem to
help). Is there anyway to prime or help this process along the way?

I think your problem may be that you don't fill the bowl, or have the
wrong Racor. Ours unscrews on top, the filter drops in. I can switch
filters without bleeding. When I do the primary (on the engine), it
takes about 5 minutes to bleed.

Note that there's a third bleed on the high pressure pump (follow the
line after the primary filter). Wasn't mentioned in our owner's guide
and it sometimes is the problem.

If you still have a problem, I "built" primer when I misdiagnosed a
problem: Outboard fuel bulb, hose and male and female fittings to let me
put it in line when I need to move a lot of fuel. Fills the bowl
quickly, then I take it out of line.

I also change filters in the Spring, after running for a while -- to
catch that spring load of critters.
