Can anyone give me an idea of what I have. I purchased a new boat (to me) from AZ. These engines are to quiet for me
I am going to change them out to tips with internal flappers.

they are corsa tips, they are the only one's using that type of flapper.

Thanks. I did a search and that is what they look like. I have not found prices or who sells them, so I will keep looking.

Corsa. Is there something wrong with them. I think they have a lifetime warranty. Anybody that sells Gil Marine stuff should be able to get them.

They are to quiet for me. I like to hear the roar of the engines when I scream up the Mighty Mo

Just cut out the center discs.

have you ever done that?I have the same tips on my boat and was thinking of replacing them.
If removing the disks is a option I might do that.

Never done it myself, but some local guys I have talked to did it. Not sure exactly what they used to cut them out. I've always had straight tips with clamp on mufflers.

Use a hole saw go slow and use a lot of lube
