Make sure your thru-hull-pipes have rubber flaps or better internal flaps or both. As for the thru hull pipes you can choose mufflers of course.
Pretty much.
Do NOT seal them with 5200. The guy that had my boat before me did that and it was not fun getting them off. If you ever want to change tips, blow out a flapper, re-rig something you will hate that. The factory uses a gasket.
You will want to seal the inside of the holes with epoxy before installing the tips. Let that cure and them install the tips. If for some reason you feel like you want to seal around the tips, use 4200 or less.
