Exhaust Riser Kit (3 inch)

Mercury Marine Exhaust Riser Kit (3 inch)

The Mercury Marine 93320A15 Exhaust Riser Kit is a genuine factory OEM part designed to raise the exhaust elbow by 3 inches (76 mm) on compatible MerCruiser sterndrive and inboard engines. The kit includes two full spacers and two restricted spacers, making it the correct fitment solution for a broad range of V-6 and V-8 MPI-equipped MerCruiser applications from the 2001–2002 model years.

This kit is compatible with 2001–2002 MCM (sterndrive) 4.3L MPI engines with serial numbers 0M300000–0M614999, 2001–2002 MCM (sterndrive) V-8 305, 350, and 377 cid MPI engines with serial numbers 0M300000–0M59999, and 2001–2002 MIE (inboard) and Tow Sports V-8 350 and 377 cid MPI engines with serial numbers 0M300000–0M316999. Additionally, fitment has been confirmed for 1998-year MerCruiser Inboard Engines including the 350 MAG [MPI HORIZ], 350 MAG [MPI SKI], 350 MAG [MPI], 6.2L [BLK SCORP], 6.2L [MPI HORIZ], and 6.2L [MPI] models, as well as MerCruiser Stern Drives including the 350 MAG [ALPHA MPI], 350 MAG [BRAVO MPI], 4.3L [ALPHA MPI], 4.3L [BRAVO MPI], 5.0L [ALPHA MPI], 5.0L [BRAVO MPI], and 6.2L [BRAVO MPI].

An important identification note: Mercury Marine has used two different types of exhaust elbows — cast iron and stainless steel. To determine which type is installed on your engine, inspect the elbow mounting bolts. Cast iron elbows use four long bolts, while stainless steel elbows use four short 1-inch (25 mm) bolts. For MCM/MIE 8.1L engines, a separate Exhaust Elbow/Riser Kit for 8.1L Non-Emissions Ctrl applications is required.

Due to manufacturer policy, OEM Mercury products can only be shipped to addresses within the United States.
