Abstract

A system for antifouling of a marine drive having a frame coupled to a propulsor housing may include a vibration dampening joint which couples the propulsor housing to the frame or an extension thereof. The vibration dampening joint may include an isolator connector assembly having an elastomeric member which is clamped between the propulsor housing and the frame or the extension thereof such that all vibrations emanating from the propulsor housing pass through the elastomeric member. A power source for providing electricity may be supported on the frame. An electric circuit may have a first end coupled to the power source and an opposite, second end coupled to the propulsor housing. The electric circuit may be configured to convey electricity from the power source to the propulsor housing and thus prevent fouling thereof, wherein the electric circuit extends through the vibration dampening joint.
