OMC external tank question
 

Yesterday I had quite a screaming lot of fun trying to pick up a
mooring at Angel Island in SF Bay when my Evinrude 6 hp sudden quit on
me. I primed the bulb and restarted the engine several times and it
stopped running soon after every time.

Turns out this is now a chronic problem with the motor, which runs fine
once I start it, then abruptly quits after about a minute. Right before
it cuts out, there is a power surge suggestive of when I disconnect the
gas line when running the carburetor dry.

After switching out gas lines, I have deduced the culprit must be the
gas tank itself, that old OMC orange steel 6 gallon tank that we all
know well.

QUESTION: Is there possibility of "cloggage" in the tube that connects
the bottom of the fuel tank to the nipple on the top of the tank?

How does one take apart one of these thanks to find the problem? Is
there a screen or filter that needs to be checked periodically?

Are there exploded diagrams available anywhere on the web?

This 1975 Evinrude 6 has run pretty well up til now. I'd hate to have
to take it in, but I suspect the problem is in the gas tank.

Thanks in advance for your help,

Richard

Had the same problem with my 15 hp Evinrude. Turned out the pickup tube in
the tank had fallen off. Funny thing is the engine would run for a minute
or so and then stop. Must have been running on the fumes I managed to pump
to it by compressing the bulb. Funny also, is that I couldn't see the old
pickup tube in the tank, only the little filter screen device that used to
fit in the end of it. As if it had dissolved completely. I've been using a
gasoline stabilizer/ carburetor cleaner lately. Poured some gasoline in a
plastic throw away drinking cup to throw on a pile of brush to start a fire
and the gasoline almost immediately dissolved the bottom of the cup so maybe
that pick up tube did really disappear.

All I can say is...the original 1986 Evinrude Yachtwin 6hp and metal gas
can came with my sailboat. I immediately got rid of that can and paid
approx $35.00 for a new plastic version.
