ABSTRACT:
A marine propulsion system of the type having a sacrificial anode for corrosion protection of the casing includes structure whereby the propeller is electrically insulated from the casing and the sacrificial anode. The structure includes spacers made of insulating materials, spacers having insulating coatings, or insulating coatings on the surfaces of the propeller or the propeller shaft. Electrical insulation of the propeller prevents unsightly and efficiency-reducing depositions on the propeller surfaces and reduces the required size of the anode.
