I have a 1989, 21 ft Bayliner with a 3.0 L OMC engine and Cobra Outdrive. The boat has been trailerd until now. I am going to keep it in a slip in saltwater in Southern California. I am putting botton pain on the boat and also painting the outdrive. I wanted to check the zinks to see if they had eroded. I took the zinks off and took the to west Marine and compared them to new ones. They appear to be exactly the same size as the new ones and appear to be the same shapes. It would appear the zinks do not need to be changed by their size. They look a little like aluminum does after severaly years. My question is this: The ones at West Marine are noticably heavier in wieght than the ones on my outdrive. The West Marine clerk stated that the ones I have on my boat are for fresh water that is why they are lighter. And also stated they would not function properly in salt water. Does anyone know if this is true. If so is there anything else on my engine that should be changed to allow it to be operated and left in the mater. thankf you.<br />Jerry
