Hi,
I'm a new owner of a Catalina 34 1995 with M35 engine (hull 1292). The main recommendation from the survey was to change the Exhaust riser. It looks like Catalina D offers 2 exhaust risers that can fit my engine and differ only at one end that attaches to the engine flange. Part Z3055 use a normal elbow and a nipple to attach to the flange. Part Z4491 use a street elbow and therefore doesn't need a nipple.

My question is ... can I use either? if yes, what are the pros/cons of each part. If no... how to I check which one fits my engine? (remove the thermal jacket?)

Part #: Z3055
