Quicksilver Exhaust Elbow Riser Kit Port Side

The Quicksilver 8M0154270 Exhaust Elbow Riser Kit is a genuine Mercury Marine OEM replacement part engineered specifically for the port side exhaust system on 2008 and newer MerCruiser MCM sterndrive and MIE inboard engines. Compatible with V-6 and V-8 powerplants displacing 305, 350, and 377 cubic inches that are equipped with Emissions Control (EC) exhaust systems, this kit delivers a precise, factory-correct fit with no modifications required.

Each kit contains one port side riser assembly. As an authentic Quicksilver OEM component — not an aftermarket substitute — it meets the original engineering specifications set by Mercury Marine, ensuring reliable sealing, proper exhaust routing, and long service life in the demanding marine environment.

Owners operating vessels with fresh water cooling (closed cooling / FWC) systems should note that this elbow does not include the FWC-specific elbow gasket. The elbow gasket part number 27-8M2004606 must be ordered separately for closed cooling applications. Standard raw-water-cooled engines are not affected by this requirement.
