I think he's referring to de-carboning an engine which can increase
compression. It's an easy DIY procedure and can have significant results.
I'd suggest searching the "forums" at www.iboats.com or do a google

search
on this newsgroup to find out more.

There is a FAQ on Iboats:
http://www.iboats.com/cgi-bin/ubb/ul...ubb=forum;f=36

Look under decarboning and you'll see excellent descriptions on two
methods - the "tank" method and the "spray into the carbs and cylinders"
method. I've done both. For me, the "tank" method is quite a bit easier
and I felt I did a more thorough and better job doing it that way.

Merc makes a product to do this called Power tune. OMC makes a similar
product (called Engine Tuner??). The other major manufacturers probably
make similar products for decarboning, tuning, ring free-ing, etc. This
past week, I used Seafoam which is readily available at autoparts stores

in
the US and Canada (Carquest, Schucks, and NAPA are some I personally know
of). It comes in liquid (called Seafoam - for tank method - this is what

I
used) and aeorosol (called Seafoam Deep Creep - for spray method) and is
recommended by many on those forums.

I believe any of these products (as well as others that might be

available)
can be used on any engine - following instructions of course. So use
whichever one you can easily obtain.

By the way, there's many discussions on de-carboning, compression, etc. in
those iboats forums - do a search on that site to find more than you care

to
know. Again, it's an easy DIY and "generally" thought to have beneficial
results both as a preventative as well as a treatment.
