Flushing Adaptor for 4 Stroke Mercury Mariner Outboard - 3/4 INCH GH x 1/2
Part No: 46276-AF
The outboard should be flushed after every use in salt or dirty water. Freshwater flushing with clean water will dislodge most contaminants (sand, silt, mud, etc.) and force them out of the passages in the cooling system. It will add years of life to your outboard.
Part ordered was out of stock however they moved earth and mountain to courier the part to me next day so 5 stars to this crew who cared business to business to get the part needed.
