Product Details

The Sierra 18-6111 Magnesium Anode is a sacrificial anode engineered to protect the underwater metal components of Yamaha outboard motors from galvanic corrosion. Built to OEM standards, this replacement anode meets or exceeds the performance of the original factory part it replaces.

Why Magnesium?

Magnesium anodes are the preferred choice for freshwater use. Magnesium is more electronegative than zinc or aluminum, making it the most active sacrificial metal in low-conductivity freshwater environments where zinc anodes are far less effective.

Key Features:

  • Magnesium alloy construction optimized for freshwater corrosion protection
  • Sacrificial anode design protects surrounding metal components from galvanic corrosion
  • Built to OEM standards — meets or exceeds original equipment specifications
  • Direct replacement for Yamaha outboard motor applications
  • Easy drop-in installation with no modifications required

Regular anode replacement is a critical part of any marine maintenance routine. As the anode depletes, it should be replaced before it is consumed past 50% to ensure continuous protection of your outboard's lower unit and drive components.

Great prices. Thanks again

Quick and easy, hopefully shipping is the same!

I ordered the Yellow Top D27F battery for my 2010 Tundra. It's a nice fit and I needed a more powerful battery for the cold months and my extra electronics, winch and lighting...we like to night wheel and I don't want a standard battery to leave us stuck in the woods. I have Yellow Tops in the Tundra, Jeep and STi...next and last will be my wife's Murano. Highly reliable battery and in my 10-12 years of owning these batteries, they are flawless and perfect. I was in Kansas working during the high heat spell near Hill City and the 116 degree heat killed my factory battery, straight to the Yellow Top for a replacement and I had no problems thru the duration of the job. Autoplicity had a great price and the shipping was perfect and fast. Only issue on the entire order from Autoplicity is the battery and packaging. I know how Optima packages their batteries with the tray portion and protection on the top. This battery was just in a box with formed protective packaging around it. The Yellow portion on top is beat up and scratched. I'm proud of how my engine bay looks and having a battery that looks 2-3 yrs old on appearance is something I am not thrilled with. I tested the voltage and it was good, just no idea if this is a new battery or not? Unfortunately, I can't return it because my truck has been just sitting in the driveway for three weeks since the battery is shot and I've been waiting for this battery.

Best prices online for hard to find parts!

EXCELLINT

I was skeptical about Autoplicity since I hadn't heard of them before, and that their price was 12% lower than anyplace else I could find. Plus, I couldn't even find a store around here that carried the X-jack. Plus I got it delivered right This my door fast. You people are Excellent!

Wow what a deal on mu Subaru husky liner floor mats and low shipping thanks Autoplicity
