Pre-1988 Mariner Outboard Powerhead Gasket Sets

Powerhead Gasket Sets

If you are breaking down a power head to work on replacing pistons, connecting rods, bearings and other internal engine components, you'll need a powerhead gasket set to put everything back together. Please note that some powerhead gasket sets do contain a head gasket, and some do not. Typically, sets contain gaskets for everything attached to the main engine block such as the thermostat cover, water jacket, exhaust housing, powerhead base, carburetors, air silencer and so forth.
