Greetings,

I just picked up a 1980 Catalina 25 and need to know what size MSD portapotty fits
well in my boat? Thanking you in advance.

Likely a Thetford or Dometic basic model.
Got the keepers mounted on the head sole?

IMO, the 2.5 gal model is too small to be worth the effort to pump it out. Go with the 5-6 gallon SeaLand 965 MSD or the Thetford 55P MSD. No one has ever complained that their holding tank was too large.
