Stus-List Re: Engine Oil Staining Transom

[james drew via CnC-List]

After a thorough scrubbing and cleaning of old residue try Penetrol coating.  
It was originally designed tor coating the inside of gas pipelines to stop them 
from corroding. The gelcoat has to be clean or it will film over any residue or 
oxidation. They make a Marine version but the lumber store product is pretty 
much or the same product. Safe on fibreglass just due prep work.
Good luck.james

I obtained an old two-stroke Suzuki Sail-8 for my first outboard for my
24. It has a few issues, one being is flings small amounts of oil at the
transom, so now I have some minor staining. It's less of a spot, and
more of a discolored patch where the oil has absorbed.

I am looking for any kind of coating that I can temporarily use for the
season to minimize the damage until I have the opportunity to haul-out
this coming winter. Or if there is something that I can wipe the area
down with after each outing that won't damage the gelcoat (such as it
is). Maybe something  as simple as Dawn & a scrub brush?

I'd rather do a little preventive now, than have a major cleanup issue
in nine months.

Thanks in advance.

Yes, the Sail-8 has the integrated oil tank. It has a small pressure
leak, but it's not in a place that would sling the oil. It was most
likely because I had the cowl off working out a separate problem, while
it was running. I didn't notice it happening, but the amount was small,
so it would have been easy to miss.

Thanks for the detailed response, this is my first outboard, so a
learning experience.

Stus-List Re: Engine Oil Staining Transom

[Andy Frame via CnC-List]

It was most likely because I had the cowl off working out a separate
problem, while it was running. I will likely have to do that from time
to time, thus my question.

Thanks for the clear-film suggestion.

[Novabraid via CnC-List]

Dave,
Below 4 or 5hp they almost all needed pre-mix.  I had a 2hp Yamaha just like 
yours.  No reverse gear either.. Just swing the engine the opposite direction!  
But I'm pretty sure the Sail-8 and Sail-9 Suzukis had auto-oiling systems for 
mixing the 2 stroke oil.

David and Andy,
Most 2 cycle engines make for marine use in the past 25 years have oil injector 
systems with a separate oil tank that independently mixes the 2 stroke oil with 
the gasoline inside the engines.  If your engine is flinging oil up against the 
transom, it could be from a fitting on the oil tank and pump.  This assembly is 
usually under the upper cowl of the engine and would be pretty accessible.  You 
would probably find a significant amount of oil covering the inside of the cowl 
as well.
It is also possible that the staining might be coming from unburnt oil from the 
exhaust, although that usually exits the engine behind or below the engine.  
Does the engine smoke excessively?
If the oil seems to be coming from further down the engine and shaft, that 
would indicate that it was a case of the final drive oil being considerably 
over filled and is spewing out a vent hole.  Before I would run the engine this 
way for an entire season,  I'd spend more time finding the source of the oil 
splattering rather than doing an elaborate fix to protect the finish on the 
transom.  These engines don't weigh very much and are not that tough to remove 
from the transom bracket.
