Doug,
If you have an electric pump that has the oil pressure safety switch,
between the (+) on the coil and the elec. fuel pump, I would recommend
you install an bypass switch around the safety switch. I just resolved
that I had an intermittent failure mode in the safety switch that would
ground the elec. fuel pump _and_ the coil. It looks like a bad coil, ie
no spark to the distributor. I finally checked the oil pres which was
~40psi, flipped the maintenance bypass switch, engine purred to life.

Karl, check your whole ignition system, points, distributor, coil, and
plug wires for any looseness damage or wear. Your problem definitely
sounds electrical.

Since we are on stories of oddness I have 2.
First, when cruising along at modest rpm, will have a sudden shut
down. Just off. No change in sound, smell, rpm, etc just as if
ignition switch cut out. Suspecting a loose connection I proofed
all wires / connections and we'll test it out cruising around
next week. Any odd ideas to keep in mind?
Second, episodically when motoring at higher rpm close to hull
speed will have a sudden racing of the engine with loss of power.
Pull back throttle, and goes back to normal but not unusual to
reoccur. Haven't noticed it at lower speed or rpm.
I'm suspicious of cavitation but haven't thought it thru as to
causes, tests of theory, remedies or other options. Thoughts?

Jon and others,
Until two years ago, my boat also used to stall in idle when
approaching docks. Then, midway across Lake Ontario from Cape
Vincent to Sodus on a calm day the fresh water pump/antifreeze
circulator seized up. There was melting belt rubber with smoke
as the bearings stopped turning. Five days and $56 later I had
a new antifreeze circulator in place and we haven’t stalled
out since. The friction in the bearings were enough to strain
the engine into a stall.

320 hrs.
Starts and runs all day. Slowing while approaching a
dock-stalls.
Change filters, check for loose fuel lines, change crush
washers…..
Approaching a dock….stall. Always while slowing down.
Approaching the fuel dock at Dodson’s was told “I’m going
there!” By the nice man on his Hinckley. My response,
“Sorry,(engine stalls) I am.
The fuel pickup was at the forward end of the cylindrical
tank. When I slowed, all the crud would slosh forward and
block the pickup causing a stall.
Unfortunately the yard cleaned the tank and replaced it.
they also inadvertently punctured it and diesel would run
out the bottom. Found this out after a day sailing. Back
to the yard and a new tank was installed.
Unfortunately they inadvertently severed the propane line
while cutting a 2” hole in a bulkhead to run a new vent
line. It was obscured by the insulation. Found this out
when it blew up. With 2 of us onboard. ‘Nother story. I’m
sure I told it here at some point.
