nigelmoore 0 Report post Posted September 16, 2020 Good morning all, The mariner lost my gas cap while filling the boat. The gas cap is different to the water and waste caps in size. It is a 2" cap where the others are 1,3/4 inches. Finding this cap has become very difficult and the next step is to replace the whole thing when it comes out of the water! Not a task I am looking forward to. Does anyone have a line on a where these are sold? Thank you in advance. Share this post Link to post Share on other sites
