        Just install it dry you will see if it leaks or not ,, probably won’t

          The cover tends to warp over time and if a new gasket is installed dry, it will probably leak. Once the cover is off and cleaned up, lay a straight edge along both sides. Any warping will be obvious. The cover can be pressed back to straight but it is brittle and may crack. Lapping with some 220 wet n dry is another option to true it up. A light coating of gasket compound will help prevent any leaks. Don’t forget to pick up a new 310058 (18-0182) seal for the t-stat as they don’t come with one.

            Thanks I will check out the top with straight edge may have to lap. Mumbles have you checked out Marine Parts Supply in Nanaimo B.C. for parts? Thanks again Russ///

              Can’t say I’m familiar with them but I have dealt with Harbor Chandler and another place up on Stewart Ave in the past.

                I like to install thermostat gaskets (and the screws, too) with a LIGHT coating of grease. That way, you can inspect the thermostat, or check for water flow a couple of times, if need be, without having to buy a new gasket every time.

                Long live American manufacturing!
