" As I cannot get parts for my 4hp Yanmar PMBY saltwater cooled engine, and it is starting to blowback more than I can live with, I need to pull the liner. A firm here can make a new liner to utilise the old piston. My worries are.
1. Will the liner pull out cleanly without damaging its seat considering it is very likely well calcified after 40 years or so?
2.The new liner material may not be up to the specs of the original. Where can I find info on liner material for use with salt water. I replaced the rings about 3 years ago which helped for a while, but more drastic action is now required.
Any help would be much appreciated. This engine is used as a generator on my boat, and among other things keeps the beer cold so has considerable importance!
Thanks in advance , Jack Hargraves. "
