Product Details

The Sierra 18-6125M is a magnesium transom plate anode engineered to provide reliable galvanic corrosion protection for Volvo Penta sterndrive systems. Designed as a direct replacement for OEM part, this anode mounts to the transom shield and sacrificially corrodes to protect surrounding metal components from electrolytic damage.

Magnesium anodes are the preferred choice for fresh water environments, where their higher electrical potential provides more effective galvanic protection compared to zinc or aluminum alternatives. Sierra manufactures this anode to meet or exceed original equipment specifications, ensuring proper fit and performance.

Key Features:

  • Material: High-purity magnesium — ideal for fresh water use
  • Replaces Volvo Penta OEM part number 3855610
  • Direct bolt-on transom plate design for straightforward installation
  • Meets or exceeds original equipment manufacturer specifications
  • Backed by Sierra's limited lifetime warranty against defects in workmanship and materials

OEM Cross-Reference:

  • Volvo Penta: 3855610
  • Sierra Aluminum equivalent: 18-6125A (replaces Volvo Penta 3586461)
  • Sierra Zinc equivalent: 18-6125Z (replaces Volvo Penta 3854130)

Sierra marine parts are engineered to deliver dependable, long-lasting corrosion protection, helping extend the service life of your sterndrive components season after season.

so far so good. hope it can be delivered fast. only issue i had is there was no estimated time of delivery or indication if it was stock or not.

Quick an easy.

easy and informative. thank you.

Easy checkout and great price!

Very easy

Quick Ship. Thanks. Low Prices.

I've thought about this...Better communication would be a plus. However, the shipping is quick and I did get an email telling me my product was shipped. I purchased window visors for my '07 Silverado. I will do business with Autoplicity again.

I wanted to order a couple of difficult to find accessories for my new Jeep Wrangler. Autoplicity not only had the items I was looking for, but had them at a very reasonable price. The two items were shipped separately but arrived in short order. Thanks to Autoplicity for filling my order #7860 of 3/26/12 quickly and accurately. See you again soon.

what an awesome site!
