You might want to crank on a hose and make sure it is going to crank and run
properly before going to the sea and having a problem.

Once you get to the lake, run the engine at varying throttle settings for
the first few hours of operation. You should not run it above 4000 rpms
except for very short/quick blasts.

To verify there are no fuel problems - run it up to about 3000 rpms and then
engage the choke. If it boggs by about 1000 rpms everything is fine. If it
does not bog choke may not be working. If it picks up speed then you have a
lean condition and need to get it fixed quick.

After the engine is good and warm and everything else checks ok, - run it
for about 15 seconds wide open and then kill the engine (don't idle). Pull
the spark plug and verify that it is burning properly.

Once you get home, pull the gearcase bottom screw and let a small amount of
grease out to verify no water from a bad seal.

That should be it. Enjoy.

Hi,

My family recently bought a new 6HP 4-stroke Yamaha outboard engine for
our little boat on the Adriatic Sea. It is going to replace the old 4HP
Tomos engine which is approximately 28 years old.

This summer, when we use the new engine, is there any procedures we
should take before putting it onto the boat and running it? Any special
unpacking, oiling, running in cold water before it can go to the boat
and into the sea?

Thanks
