I'm not certain of this but does your manual indicate the manuf'er? I still have some of the stuff required for my packing
box although it has been a while since I replaced the flax...yes, I actually did it myself.....I have the little hook-ie tool to remove the old as well.....but with the tool it was not hard or even time consuming.....I ordered the flax from WM and I think
they or Westerbeke were my source of info.....I know I'm not a lot of help......Patrick
