I'd be looking at replacing the fuel pump and all the supply side hoses.
Not a huge expense. Especially if you have a spare fuel pump already. If
you don't have a spare, I'd strongly recommend getting one. I suspect it's
the same pump as my 25XPB, Westerbeke Part 039275. Westerbeke wants $256
I agree with you regarding purging air, warming up not so much.
If your purging air theory is correct, there must be a small air/vacumn leak
somewhere in your system between the tank and injectors that lets air in the
system while the boat in sitting in the water between your uses of it.

I posted a few weeks ago about the electric fuel pump on my Universal 25XPB

driven fuel pump. There is a plate that covers the spot where a cam driven
pump should be.
Fortunately I had a spare fuel pump. We were in open

On my Universal M4-30
On my Universal M4-30, things work differently. The fuel pump is energized
when you turn on the key switch, so that ticking starts before starting the
engine and doesn't stop until you turn off the key switch. I think this is a
better way to operate the system and I don't understand why
Thanks Niel,

David,
This may be a long shot, but on a Universal M3-20B that I installed on a
club launch, and I think all Universals, the fuel pump gets its power
under normal running conditions via an oil pressure switch. When
starting the engine, the glow plug switch energizes the electric fuel

David, on a couple of different engines. I've had the electric fuel pump
fail intermittently. While bringing my Sabre home the oil pressure would
drop off randomly and the engine would bog down also randomly. When both
happened at the same time I began to panic that the engine was thinking of
Apparently you have an electric fuel pump. Some of these, at least the small
one I use, have in-line filters
that are built into the pump and not removable—they are integral to the pump.
The only way to replace the filter is to replace the pump or have 2
pump/filters in parallel so they can be
Dave,
Start with the fuel tank. Look for crud in the tank and in the screen for
the fuel pick up. Check every hose clamp in the system. Be sure the
overflow outlet is not plugged. Be sure top of Racor is seated properly
and vacuum gauge is tight. Change the filters just for peace of mind.
So I am back to my engine problem hoping someone can help clarify things. I
have had the engine quit several more times, but with no consistency as to when
or why it happens. We were on a cruise recently and used it often and for long
periods going in and out of harbors. Mostly it worked fine

My old Catalina had an A4. We had a similar issue to the stalling issue, the problem turned out to be a small crack in the distributor rotor. As it would heat up, the rotor would deform and no longer make good contact with the points. I was happy to move to diesel when I upgraded to my C!Jim
Karl- I agree with Neil that it sounds like transmission, but I have not had
that problem so no personal experience.
As long as we are onto other engine strangeness, my M4-30 dies routinely when
shifting from neutral to reverse at minimum throttle unless I kick the rpm up a
bit. I suspect
AT4's are known to be susceptible to internal shorts in the ignition coil.
If it sits for 15 minutes or so then restarts, that may be one culprit.

If you have a gas engine, there might be a filter at the end of the pickup
tube (in the tank). Pull the tube and check to see if it's clogged. My
previous boat had an Atomic Foiur engine. After many years, it would run in
idle, but not at speed. When I pulled the tube, there was a filter that was
