Abstract

An anode mounting structure for a marine engine including a metallic gasket mounted on the mating face between components of the engine, such as a cylinder head and a cylinder body, which form a coolant passage extending across the components, and an anode for corrosion prevention facing the coolant passage, in which the anode is attached to the gasket.

Independent Claims | See all claims (14)

  1. 1. An anode mounting structure for a marine engine comprising a metallic gasket configured to be mounted between components of the engine formed with a coolant passage extending across the components, and an anode configured to prevent corrosion of the engine and disposed so as to face toward the coolant passage, wherein the anode is attached to the gasket.
  2. 11. An anode mounting structure for a marine engine comprising a metallic gasket configured to be mounted between components of the engine formed with a coolant passage extending across the components, and an anode configured to prevent corrosion of the engine and disposed so as to face toward the coolant passage, and means for attaching the anode to an exterior of the gasket.
  3. 12. A marine engine comprising an engine body, the engine body including a first portion having a first mating face and a second portion having a second mating face, the first and second portions being removeably connected to each other with the first and second mating faces facing each other, a gasket disposed between the first and second mating faces, a cooling passage defined by at least one of the first and second portions, and at least one sacrificial anode connected to an exterior of the gasket so as to be exposed to fluid in the coolant passage.
