Quoted from Beemus:Fwiw I installed a 7 7/8" plunger yesterday since not all plunges were "clean". Plunges much better now. Not sure why stern uses the shorter 7 5/8" plunger. Tip now rests gently against ball. Slightly off center, yes, but of no concern with longer plunger.
For the record, Auto plunge mech adjusted to prevent strikes to pf. Deburred too.
Nice job. Is that a light you have in there?
