Sierra 18-4442 Engine Alignment Tool for Cobra Stern Drive Models

The Sierra 18-4442 Engine Alignment Tool is used to verify engine alignment on Cobra stern drive models. Proper engine alignment is critical to stern drive performance, since a misaligned engine can cause premature wear on U-joints, gimbal bearings, and the drive coupler, along with vibration and reduced power transfer to the drive unit. This tool gives installers and marine technicians a reliable way to check that the engine and drive coupler line up correctly before final assembly, rather than guessing or relying on visual inspection alone.

Sierra manufactures replacement and service parts engineered to meet the demands of high horsepower marine engines operating in harsh marine environments, and Sierra supplies parts and tools to OEM engine manufacturers and boat builders. The 18-4442 is sold as a genuine Sierra branded tool intended for use in Mercruiser-related engine coupler service work.
