We offer the exhaust flange gasket for this particular exhaust flange. See "May we also suggest" below.
1) CAUTION! This exhaust riser must be used with a properly installed thermal jacket. Due to the extreme fire hazard, we include the appropriate Thermal Jacket with each riser. Installing a riser without a thermal jacket is an extreme fire hazard that could cause death or serious injury and the complete loss of your boat.
2) We cannot overstate or take responsibility for the extreme danger inherent in an inboard engine's exhaust installation. We strongly recommend you have an experienced boat yard perform exhaust system repair or replacement.
3) Never run your engine without a properly installed Thermal Jacket. In every Catalina installation there are combustible materials close enough to the riser to start a fire.

5) Although this part number represents the part used on the boat described above, there can be subtle changes from boat to boat. We will need your old exhaust riser to achieve a proper fit.
