Exhaust Riser C-350

Part #: BA9559
$324.20
Westerbeke OEM "mixing elbow." We generally call these exhaust risers and this design is slightly different in that the raw water is injected up stream to help cool the complete unit eliminating the need for a thermal jacket. This design is often more compact than Catalina's custom risers which are required on other models given the configurations of the engines in relationship to the aqualift mufflers.

1) When you order this special order item it sets off a chain of events like Willie Wonka in the chocolate factory. Once you turn the valve the chocolate is coming down the pipe. If you then decide you want caramel, the chocolate is still going to come out of the pipe. We can't put the Chocolate back in the pipe, so someone is going to have to eat it, and it's not going to be us! Your order can't be canceled, returned, or magically changed into caramel, so please order carefully the first time!

2) A 50% deposit will be billed when your order for this item is accepted. The balance will be billed when the product ships
