Mufflers are never a positive as far as performance goes. However thoes slip-in's are not very restrictive. I wouldn't worry about your tune up. Stick um im and go.

Even if the mufflers dont quiet it down enough to be legal you should still install them.If you get stopped having them in your headers will show the boat police you are at least making an effort to comply with the law.It may be the difference between getting a ticket or not.You will have to install them and run them to see if you will need to re tune your engine.Get a gps speed reading on your boat then install the mufflers and run it again and you will see if you loose any performance.
