Since your current pipe has a 3-1/2 inch outer diameter it most likely has a 3 inch inner diameter (measure this to be sure) which would mean that you'd need a 3 inch spigot to lug fitting adapter like part # T1029-1 as this will slip into the pipe and give you the type standard lug fitting for the standard size bayonets to attach to.

The # T1029-2 is made from ABS plastic.

Hi. I have a 2004 Sunseeker and the sewer outlet is a bayonet 3" connector. One of the little plastic stubs broke off so my sewer hose connection is not as tight as it would normally be with 4 stubs. What are your recommendations for putting a new fitting in place? How does the old one come out? Do I need some sort of chemicals to loosen the glue and pull it out or can I just twist on a new fitting and glue it in place over the old fitting? Should I cut the old one out? Thanks

Your best option will be to actually cut off the existing adapter and then replace it, using some ABS Solvent Cement like # A05-0303. It might also be worth it to have a technician come in and replace it if you're not comfortable doing this.
