Parts Desk Insights
This motor is the go-to solution when your outboard's trim system becomes sluggish, fails to hold position, or stops responding entirely. It's best suited for boaters who want a reliable, American-engineered replacement that installs without modification. If your engine also has starting or charging issues, consider pairing this with a compatible ARCO starter or starter solenoid. For heavy-use or late-model Mercury applications, see the ARCO Heavy-Duty Tilt/Trim Motor (57-6250).
