Its a fresh water system ... the boat/motor runs quite strong so timing
is good however your point on the flushing is good! I havent had that
looked at. would a flush clean things out or is there parts
replacement necessary? thanks you've been very helpful ....



Freshwater systems can be flushed out with acids to dissolve the
accumulated rust plugging up the smaller passages. That engine has had
plenty of time to load up on corrosion.
