The SIERRA 118-6849 alternator is a critical component of your charging system, ensuring reliable electrical power for your vessel. Designed with 12V and 80A specifications, this unit is built for longevity and stable performance in harsh marine environments. Due to the nature of the aftermarket parts industry, compatibility with specific outboard engine models must be verified individually. We recommend comparing the catalog number 118-6849 with the original OE (OEM) number available in your engine's technical documentation. If you have any doubts about fitment, we strongly recommend contacting our customer support to verify compatibility and avoid ordering errors.

Installation and Operation

Replacing an alternator requires precision. Before starting work, ensure the battery is disconnected to prevent short circuits. Check the condition of drive belts and cable terminals – clean and secure connections are essential for 80A performance. After installation, we recommend checking the charging voltage at idle and under load to ensure the new SIERRA alternator is functioning correctly.
