This exhaust riser is equipped with a rectangular flange to fit Universal Diesels. Your riser may look different. Compare your riser dimensions to those in the secondary images. If yours does not match those then you must send us your old riser to achieve a correct fit.
• Catalina 28 when equipped with a Universal M3-20 engine.
We offer the exhaust flange and 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.
