Re: Straight running?????
That is called an ANODE. Electrolysis is a process where metals exposed to variable electric potentials (your engine in water) will cause the metals to erode. Your engine should have the one you mentioned, as well as another one on the bottom of the engine mount lacated on the transom of the boat. If it is badlr erroded it should be replaced (about $10). There should be a bolt holding it on to the engine. try looking above the anode, you may find the head of the bolt there, loosen it, move the anode slight opposite to the direction of the prop rotation, and tighten. It may take a few tries. If the anode looks more than 25% erroded, replace it. It is a lot cheaper than a new prop or other Lower unit parts!
