The port hole (light) in the Head of my 2000 340 Sundancer is leaking. The port side of the boat faces south so that that port (hole) light (and the boat) is in the sun for most of the day. So, I am "guessing" that the rubber gasket in that port hole is dried out from the exposure and heat?

The SeaRay parts manual lists that the part is made by Bomar and the part number as: 1331735. However, I cannot find any marine parts store that can confirm that they carry that correct replacement gasket part.

Can anyone provide any recommendations/suggestions/guidance where to look for the replacement gasket?

Thanks

Is it leaking from the window/gasket or from the frame and dripping down the wall?

If it is from the window gasket you make be able to tighten the dogs to get a better seal. If not you may need to replace the gasket.

If it is from the frame you may need to remove and re-bed the seal.

Kevin,
I don't have any pictures of it yet.
Also, I have tightened the dogs and it still leaks. So, I may have to replace the gasket and/or re-bed the seal.... Thanks
 
Sea Ray part numbers are typically only useful with a dealer. Sea Ray still has plenty of those seals available - you could get it from your dealer, if you want. The dealer may even have them in stock.
 
I used to spread a very light coating of Vaseline on the gaskets to keep them soft and pliable. I believe this was even recommended by the company that made them.
 
Go2marine has the gaskets as well. I had the identical issue. There's a thread on here about replacing them. I've done every portlight over the last couple years. The port lights are hard to close with the new gaskets for a bit as the material flattens out.

Your portholes are exactly the same as my 97 330DA and the replacement screen/gasket kit is the same.
Here are two threads that have the info you need:
