20 yrs on zincs, wow. was your boat in a marina or at home? marina's tend to eat zincs as you are contending with alot of electrical activity in the water, problems are usualy with a boat with electrical problem. now that you are in the salt and at a Marina, you can expect your zincs to go away, you may have to increase the number on the shafts and the size of the others as well. zincs should last 9m to a year.

You may be talking about boats is salt water. Boats in fresh water frequently are not even equipped with zincs; the ones that are almost never have any noticible loss. We had a steel workboat at our yacht club and I installed magnesium anodes on that boat to prevent the slight amount of electrolisis from attacking the steel hull. They now sell magnesium shaped anodes in our area. I have never seen a zinc anode in a local marine store. They would special order them. Forget about the engine pencil anodes. No one even knows what you are talking about. I pulled the (original) pencil anodes out of our Crusaders and wire brushed the mineral deposits off. I compared them to new ones and there was no difference. Our boat is a 1986 so you can see that anodes don't go away in fresh water as I know it.

Gentlemen, I an not here to ruffle any feathers. It has always been my idea that this forum is here to resolve boat related problems and how to make repairs or adjustments. Along with doing it with the least amount of money. As with any group and with the size of this one there are many many opinions. It is quite obvious that there is a tremendous amount of knowledge here and each person can contribute something. I suggested Maynard change to a little larger fuse. I thought that this would be the safest and least expensive to try before spending any big bucks in order to try to resolve his delima. Since we lacked any real electrical information. Like voltage or amperage or occurrence. I believe if it ain't broke don't fix it, keep it simple and inexpensive. I have worked 40 years in the electrical and mechanical engineering end of many multi million dollar projects. I don't suggest things that I don't have a back ground in or knowledge of. Nor do I try to over complicate the issue such that the non engineer can't understand.

Maynard, If you have had those zincs that long. I would be very wary. There was a big thread on zincs here about a year ago. Although it is not done very often Magnesium is used for fresh water and zinc for salt water. It has been the norm for years to use zinc every where. Maybe its the cost or lack of knowledge. West Marine in the Toledo area does not even stock Magnesium. You have to order them special. I don't use zinc on ether of my boats. But I'm not in salt. Just my 2 cents worth. Sorry for the long thread. 12:06 Time for lunch and a beer.
