Quicksilver 93320A14 3-Inch Exhaust Riser Spacer Kit for MerCruiser Stainless Steel Elbows

The Quicksilver 93320A14 is an OEM 3-inch exhaust riser spacer kit designed exclusively for use with stainless steel exhaust elbows on MerCruiser sterndrive and inboard engines. This complete kit raises the exhaust riser elbow by 3 inches, helping maintain the proper height above the waterline to prevent water from backflowing into the exhaust system and engine.

Keeping your riser elbow at the correct height is a critical part of exhaust system maintenance. Over time, worn or improperly positioned risers can allow water ingestion — one of the most common and damaging problems in marine exhaust systems. This kit provides a straightforward solution with all necessary hardware included.

Important Note: This kit is designed to work only with stainless steel exhaust elbows. It is not compatible with cast iron elbows or dry joint exhaust systems.

• 3-inch riser spacer blocks
• Mounting bolts
• Gaskets
• Nuts and washers

Key Features:

This exhaust riser spacer kit is a genuine Mercury Marine / Quicksilver OEM component, ensuring precise fit and long-term reliability for your MerCruiser exhaust system.
