Raymarine 2KW Radome "O" Ring
 
My radar unit recently quit working, after trouble shooting I determined the problem was the "O" Ring that connects the drive motor to the antenna assembly. It appears that you can no longer get this part from Raymarine. In my search on the web one poster indicated it was 4" O-Ring that could be purchased from Amazon or Ebay. However, I would think that you would need to know both the inner and outer diameter to find the proper O-Ring. Looking for any help in locating a replacement "O" Ring.

You could do the math or just tie a piece of string snuggly around the wheels and measure it. Then buy several o-rings of that approximate size and test them out.

Ive seen full 2KW units for sale on eBay, maybe someone sells parts there too.

Its a 241 Buna o-ring 70A durometer, black, 3 7/8" id, 4 1/8" od, 1/" width. Amazon sells a pack of 25 for $9.99. I replaced mine with this and it works fine. 25 is many lifetimes of radar o rings.

Thanks, that was exactly the information I was looking for!
