      has anyone replaced the plastic in the fuel gauge sight glass in the cockpit sole? I can barely see the gauge through the lexan and would like to replace it. I removed the aluminum ring from the cockpit, but I can’t figure out how to get the lexan out. The bottom ring which I thought was a rubber gasket seems to be made of metal as well. Any ideas would be appreciated.

      yes, it’s a bitch. I haven’t replaced mine, but a
      trick I use is to make it wet with a film of water and
      shine a flashlight through it to see the gauge. I
      don’t need to do it often, so it’s not so onerous a
      task. Try to sail as much as possible.

      Rodd,

      I changed the old plastic sight glass in my fuel gauge viewing portlight. It was held in place by an aluminum retainer ring that was designed to screw out of the body of the portlight, which is threaded for the purpose on the inside. However, it was not designed to do this after 30 years in a marine environment, and nothing I tried worked to free it up. Finally, I cut the ring in two places with a Dremel tool and broke it out. I then put in the new lens with a fat bead of 4200 adhesive bedding compound. If I ever have to change the lens again, I figure I’ll just cut the bedding with a blade.

      Good luck,

      Tor

      I never liked the idea of having to get down on my hands and knees to view the fuel gauge. I used to pour a little water onto the sight-glass to make viewing the tank gauge easier. You might consider replacing the manual fuel gauge with a remote gauge. It uses a generic sender screw pattern. If you go this route, pull the old sender and bring it with you to the marine store to be sure.

      The issue is where to mount the fuel gauge meter. For some odd reason, none of the engine manufacturers have a fuel-gauge option on their instrument panels. I ended up making my own panel. I painted the sight-glass gray. You still need an access port to the fuel tank, so removing it and glassing it over is a bad idea.

      If all else fails, you could just put the meter behind the existing panel where you could see it when you open the back door.
