Usage Frequency: For occasional use, a 4 MLH is sufficient; frequent long-distance trips may require a larger engine or extra fuel storage.
Maintenance Comfort: Mercury’s engines are designed for minimal upkeep, but ensure you can perform basic inspections and maintenance.
Noise and Vibration: Choose engines with through-prop exhaust or similar technology for quiet operation, especially if fishing or boating in populated areas.
