heat problems usually mean an impeller or the tube from the impeller to the
engine, or the water pump. Is it like other outboards with a '****' stream of
water out the back? If so, is the water flow good and steady? It should be
about the same temp as the water around the boat, if it is hot water coming
out the '****' stream, you've found the cause

Hello,
I have a 3hp Sears Gamefisher aircooled outboard. It's Tanaka 300 with
Sears brand.
It developed a problem:
After running at full throttle with no problems for 10 minutes os so,
it'll start to cut out. The engine speed will drop fast. At first,
it'll keep running and pick up speed again, but it will cut out again
and if I don't close the throttle, it'll get so bad that the engine
dies.
Running it at low rpm for a while eases the problem: I can then get
back to full throttle and it'll take a minute or so before it starts
to cut out again.
Because of the initial time without problem, I'm thinking that the
problem is heat related.
I cleaned out the carb and put in a new spark plug, but no relief. I
also verified that there is good flow through the fuel valve and hose.
Any idea what this could be? Is it more likely an ignition or a fuel
problem? How can I troubleshoot this?
I'd appreciate any advise or pointers.
Thank you,
Michiel
fuel tank vent?
I don't think so. After reading your suggestion, I went out and took
off the fuel cap (the vent is in the fuel cap) and blew some air
through it. Seemed easy enough.
Heat seems to be a factor. After refueling, takes less time to start
acting up then after cold start.
