When I installed the 406 I decided not to install hatch springs or gas struts on the motor cover. At that time however I did replace the SS handrails and decided to recycle a few of the leftover parts. This is what I came up with and have been using for several years now and found that it works for me. Although it may not work for some of the members who have addressed supporting the hatch cover, If you need a low cost hatch support this is for you. I have two; this short one for venting and a longer one to prop open the hatch to work on the engine. If I’m on the water and want to open the hatch I place a small piece of rubber hose or rubber door stop in the port side aft corner to keep the hinges connected. This is an old idea from an old guy who thought it may help someone.
