Engine start-up
 

After a boat goes unused for 1-2 months, is there any concern
about oil circulation when the motor is started. I can pull the
kill switch so it won't fire right away and oil will start circulating
while the engine is cranked. Is that enough? I do not have a pre-lube system.

Many people believe in changing the oil and running the engine just before they put it away for the end of the season. The fresh oil will stick to the internal engine parts better than worn oil (over the winter months).

There is an old story about the synthetic oil used by the Germans in WWII. It would run off of the internal engine components during storage.

They developed a petroleum based additive that would act like glue holding the synthetic oil to the engine components.

Some Americans discovered it after the war and started marketing/selling it as Scientifically Treated Petroleum (better known as STP!)

I don't know if that is a true story!
