System for inhibiting corrosion of submerged components in a marine propulsion system

A corrosion inhibiting system, comprising:

• a primary corrosion protection device configured to maintain a marine propulsion unit at a selected potential, said marine propulsion unit being made of a first material;
• a secondary corrosion protection device made of a second material selected to act as a sacrificial anode, said first and second materials being dissimilar materials;
• an electrical conductor connected in electrical communication between said first material of said marine propulsion unit and said second material of said secondary corrosion protection device;
• and
• a continuity controller connected in electrical communication with said electrical conductor between said first material of said marine propulsion unit and said second material of said secondary corrosion protection device.

A corrosion inhibiting system, comprising:

• a cathodic protection device configured to maintain a marine propulsion unit at a selected potential by supplying electrical energy from a direct current source to a submergible electrode located adjacent to said marine propulsion unit, said marine propulsion unit being made of a first material;
• a submergible anode made of a second material, said first and second materials being dissimilar materials, said second material being selected to act as a sacrificial anode and cathodically protect said first material when said first and second materials are connected together in electrical communication;
• an electrical conductor connected in electrical communication between said first material of said marine propulsion unit and said second material of said submergible anode, said electrical conductor comprising an electrically conductive cable which extends at least partially between said first and second materials;
• a continuity controller connected in electrical communication with said electrical conductor between said first material of said marine propulsion unit and said second material of said submergible anode;
• and
• a signal device configured to provide notification of said continuity controller being activated to connect said submergible anode in electrical communication with said marine propulsion unit.
