Not sure what your dome lights look like. If they are flush mount you can replace them with something the same size or slightly larger. The dome lights in my 3300 are probably about 3" flush mount, about an inch tall, cylindrical shape, almond colored with white opaque lenses. Looking around I don't see anything that quite matches.
There are tons of replacement options out there. If you have the budget for it and plan on keeping the boat for a while, upgrade to Lumitec or Hella LEDs. I put a couple Lumitec exterior dome lights in my radar arch last year and they are great. They are dimmable and switch from white to blue using a rotating stainless bezel, and are IP67 sealed.
Here are some options:
