Replacement Gas Cap
 

I thought that I would pass along that I found the exact replacement plastic gas cap for 2000 Mariah boats. My boat is a 202 Shabah and the plastic cap snap broke. I did not want to have to replace with a new style cap so I did some research and found that BackToBoating.com sold just the cap.

4 screws hold the cap in place and its super easy to replace.

The part number is 912036B and as of this post it costs $24 with free shipping.
