Safety & Important Information
- Confirm the complete engine application before purchase and installation.
- Do not rely on horsepower alone; model, year, shaft configuration, suffix, stroke, and original part number may affect fitment.
- Use the manufacturer's service procedure and torque specifications for lower-unit and water-pump work.
- Never run an outboard without an adequate water supply.
- Professional installation is recommended when lower-unit removal or cooling-system service is unfamiliar.
- This is an aftermarket replacement, not an original equipment manufacturer component.
