Product Details

The Sierra 18-2760 is a high-performance marine exhaust tube designed specifically for MerCruiser stern drive engines. This non-corrugated exhaust bellows provides a durable alternative to traditional bellows on larger V-8 engines that create significant back pressure.

Key Features:

  • Non-corrugated exhaust tube construction for superior pressure relief
  • Includes ground clip and stainless steel hose clamp (Sierra 18-7314)
  • Hose clamp adjusts from 2-9/16 to 3-1/2 inches
  • Compatible with MerCruiser Alpha One Gen I, Alpha One Gen II (R/MR), and Bravo I, II, III stern drives
  • Prevents premature bellows failure caused by excessive exhaust back pressure
  • Flexible rubber construction allows for easier installation than OEM parts

Replaces OEM Part Numbers: MerCruiser 78458A1, 78458; OMC 775482; GLM 89150; Mallory 9-72810

This exhaust tube is engineered to eliminate the common problem of exhaust bellows expanding like a balloon under high pressure, which can cause the drive shaft bellows to rub against the yoke and U-joints, resulting in bellows damage. Sierra's aftermarket design offers reliable performance and easier installation for marine mechanics and boat owners.
