Steel Trawler

If you own your yacht trawler enough time, you've had discussions on the wharves on the topic of marine zincs on your boat, but what do they really do? How can they do their work?

When you have two different metals that are physically connected and lowered into the seawater, they produce electricity (DC) DC. Current trends linking the two metals that can corrode the metal gradually as propeller shafts, underwater equipment and strainers in engine room, all that is in contact with seawater

The anode will be used to voluntarily corrode faster than your boat in the other Metal Gear Water does.

At the top of the galvanic scale, zinc is the number 4, with 1 being the highest sacrifice to salt water, aluminum is 12, the steel is 30, is 51 brass, 316 stainless steel Stainless is 76 and pure gold is 91. Therefore, zinc is preferred, we would like it to corrode and protect the other metal in contact with seawater

Your yacht trawler zincs should be replaced when approximately half of the anode has been lost to decay. In a perfect world, we want that to happen no more than once a year, but each trawler yacht is a little different. I inspect my yacht trawler zincs often dive under the boat and the replacement of zincs in need. When the sailing vessel is removed from the water, a new full set is still installed.

Zincs are not all made the same way. zincs MIL spec request. There is a company on my links page website that I purchased mine from. zincs unsurpassed at a very attractive price.

Instruments and rudders

Propellers and shafts are consistently protected by a zinc collar bolted around the tree. It is essential to ensure the tree is clean and smooth before clamping zinc new collar for her. You need no primer on the tree at all.

Rudders and struts are also protected with discs of zinc is attached directly to metal. Be sure to paint anti-fouling does not cover this.

Hull Plate

Hull zincs plate is securely attached to the outside of the hull and are used to bind metals trawler yacht in the boat is not in outdoor salt water.

Collage is a link between zinc plates bolted to the hull to other metals by son. All gear immersed in running and the metal in the engine compartment are linked to these plates. Trust yourself check the connection between the through-hulls and other Metal Gear by using an ohmmeter electric.

plates of the hull are in good standing under the water found in the stern of the boat.

Tip: If you see "green bronze gear", the association has not been successful and corrosion is underway. Inspect and reinstall the bonding system.

On the raw water cooling

heat exchangers of the engine and engine raw water cooling systems are also at risk. Most heat exchangers are provided with a number of zinc "pencils". You detect in brass bushings. The pen is unscrewed the cap to the exchange. In addition, your transmission and oil coolers will be set with pencil zincs too

The preferred means to verify the galvanic corrosion is to attach a section of metal called a sacrificial anode, and i.
