Warm engine stalls at idle -LONG. Part two
 

Well I finally picked up the boat this past Tuesday. It cost almost
$500. They replaced the plugs on the Force 70 engine, they de-carbed
the carburators, replaced the fuel filter and ran diagnostics on the
engine. If they made any adjustments, I was not informed. I told
them that I would launch it on Saturday and if I had any problems I
would call them.

I launched it. Ran great...until it was time to come home. I was
turning 1300 rpm for about three minutes (in a no wake zone) when it
stalled. I turned off the ignition and tried starting. It just
turned over. I pumped the bulb three times and tried again. It
started. I pushed the rpm to 2200. It ran fine for about three
minutes and stalled again. I pumped the bulb three more times and it
started. I then pushed the rpm to 3800 and drove the boat back to the
launch. On my way home I dropped the boat off at the repair place and
informed them of the procedures I followed while on the lake.

Any suggestions? 89 octane mixed 50:1.

I don't have outboard experience but I'd suspect a fuel pump, leaky fuel
line allowing air to get in the line, or loose connection of the fuel line
at the engine or fuel tank.

I assume the fuel tank vent was open.
Definetly sounds like no fuel coming from the tank.
Could be a fuel pump but doubt it as it ran fine on the way to the launch.
Probably the vent or a small fuel line leak somewhere.

I picked up the boat last Tuesday. I had them replace the hose from
the tank to the bulb and from the bulb to the fuel pump. I took it to
the lake yesterday and ran it just like I had the three previous
times. It again started great, though this time I didn't pump the
bulb. It idled fine. It ran fine. Turned 3500 rpm to the other side
of the lake and did my thing with the fishing poles; drowned some bait
for an hour or so. Started the engine and it ran perfectly. I'm
convinced that the valves in the old pump bulb leaked and that somehow
air got into the fuel line. New hose, no air. Yea!
