With possibly two tropical storms on their way I figured it was time to replace the hatch gaskets. The old gaskets looked to be original so that would be forty years for this boat. Guess this job was a bit past due. This was not a hard job and took about 45 min per hatch. Gasket was a simple round EPDM rubber I found online. I am OCD when it comes to leaks so this is one less leak in our boat.
