video I made at strawberry

[2knots]

Thanks Alan, so if I'm correct, the zinc's are the hull grounding points... I'll check to make sure they have a clean connection... Thanks Jeff

Mine only has one zinc that has a ground wire running to it from the motor the other are just bolted to the motor or hull, clean the zincs Not the connections, I use a Drexel with a stainless wire wheel and clean them right on the boat
