Good afternoon everyone,
I recently bought a Southport 28 EX and after a few days, someone decided to take the cap for the water tank.
Does anyone know where can I find them?
Thank you!

Be careful on what you get. They are not all the same. Does one of your other ones fit? Take it with you to match it up.
The builder should be able to tell you what manufacture they used. Phone: (207) 620-7998
For example, Perko and Sea-Dog use different size caps. My be the same in dia but there is a bevel that needs to seat in some of the filler necks

Little trick. Get a candle and get an impression on the threads. Take a measurement of the diameter precisely. Got to a good marine stop with a really old guy. He’ll know what your doing. They are all very different caps. Good luck. Had same issue
