What is best practice regarding painting a wet liner before fitting to the block / crankcase?
The
engine in question is a
raw water cooled
single cylinder
Yanmar (YSE-8). One
service manual requires the liner to be painted before
installation with an "anticorrosive"
paint. Another manual requires the sealing lip (at the
head end) to be painted with "white"
paint during insertion of the liner. Neither are more specific regrading detailed paint type.
It would seem to me that any paint suitable for underwater use on a
steel hull should be suitable for the liner and perhaps the paint is not that important except for use on the top sealing lip. The rest of the cast iron crankcase has minimal paint protection in the
water galleries and relies on the anode for
corrosion protection. FWIW,
water temperature is around 50C (~120F).
Thoughts???
