Hi Norm
Thanks for the answer. I am asking people around here and they say it is
risky to sandblast it as sand could get into the system. If I dont do that would
wire brush pressure washing and ospho be a viable alternative. I also read
about painting the engine white to be able to see any leaks instead of the volvo
green. What do you think. I decided to build an integral watertank in the
bilge. I will glass it in, but need to apply some sort of barrier coat to the
inside of the tank. Does anyone have a name of a product for the inside of a
glassfiber water tank. The boat allready has integrated tanks for water, and I have
40gal of fuel and would like more water.
Thanks
Your engine is solid iron and sand cannot get into it except through specific
known channels such as intake, exhaust, and vent. These can be blocked
easily and reliably with care. I would sandblast my own engine (if I had the
time), and have safely sandblasted many peices of machinery, most recently a
new-to-me windlass. Wire brushes (or wheels) not only drive debris into the pores
of the metal, none can compare to the throughness of sandblasting or the
pristine results. Chemcals do not remove much and often add to the debris on the
metal.
I DO usually paint my machinery white. Not only do leaks show up readily, by
reflecting light white machinery makes for a brighter engine space with fewer
dark shadows.
As for the fiberglass water tank, I must defer to those with more experence
in this area.
