I am hoping someone out there has worked on original Kaama mufflers. I have a "new" Formula F311 with the Kaama setup. It has the original Kaama mufflers but the air cylinders are not working. Air pump is fine as are the dash controls and the air release. My guess is that the seals in the cylinders are shot. The cylinders are actually mounted inside the transom with these mufflers. Has anyone worked on these beauties?
