Boater's World is your Sacrificial Anode Center. We want to make sure enginetroubles don't keep you from having fun on the water! No matter where you choose to do your boating, we have all the right products to help take care of your boat. Read this quick overview on how to protect you engine from corrosion!What causes corrosion? Seawater is a good conductor and freshwater a bad conductor, so corrosion is worse in seawater. Generally, corrosion rates increase in proportion to the amount of oxygen in the water. However, cracks and crevices, which are areas starved of oxygen, become anodic and corrode also. Higher temperature increases corrosion rates - doubling for every 30 degrees C (55 degrees F). There are various types of microorganisms that can contribute to corrosion, either by removing protection or causing a corrosive environment.Why do I need anodes? You need anodes on your engine because when two different metals are in contact, electrons will flow from the more negatively charged metal (anode) to the more positive metal (cathode). If you want to protect both types of metal from corrosion, you must add a third metal such as zinc, although magnesium and aluminum are also used. This active metal becomes the anode for both metals. The zinc or aluminum sacrifices itself to protect the other two metals, hence the term "sacrificial anode".Do's and Don'tsDO change your anode when they are 50 percent corroded DO make sure they make good electrical contact - remove paint and clean the mounting surface.DO protect trim tabs individually (do not bond). Although they are usually made from stainless steel they can still corrode and need sacrificial anodes.DO be sure to use new fasteners on sterndrives - even stainless bolts fail as a result of corrosion.DO keep a sterndrive immersed in the water so that the anodes can work. DON'T use zinc anodes on aluminum outdrivesDON'T paint anodes. They will not work to their full potential!DON'T mix anode types - aluminum anodes will try to protect zinc.DON'T use magnesium anodes on outdrives in salt or brackish water as it will "overprotect" the aluminum.

Heavy Duty On-Board Oil Changing System - GP-700 SeriesThe GP-700 series of oil change systems were designed to offer users a more powerful pump than our standard impeller series. Vessels which require longer hose runs and owners who wish to pump oil up onto the dock can utilizethese systems with confidence. A Bronze gear pump with helical gears and viton seals offers users one of the most powerful oil change systems on the market. Designed for vessels in the 40-80' range these systems provide faster oil changes and expanded flexibility on the location of the drain and fill containers. With a flow rate of 2-3 gpm this system is ideal for the sport fisherman and motor yachts with engines in the 500 to 1500 HP ranges. Like all REVERSO systems the GP-700 series has a reversing motor and is fused at the unit for safety. The Bronze gear head is designed to be serviced if required without the disconnection of hoses.

The search for a true saltwater fillet knife has ended with the introduction of the new Saltwater Piranha from Mister Twister, the industry's pioneer in electric fish cleaning technology. Every bit as rugged as the classic Mister Twister Electric Fisherman, the Saltwater Piranha's increased cutting surface is engineered to handle the tough scales and skin of many saltwater fish species. While the Saltwater Piranha features 25% more torque and 15% more speed than most other electric knives, the real key to its cutting power is in its 8" heavy duty stainless steel blade; hundreds of serrations willcut through just about anything. More power, more torque, and more speed couple-up to truly make the Saltwater Piranha, "Bad to the bone!" The Mister Twister Saltwater Piranha...Superior mechanics means superior results!
