Fuel – The Most Obvious Part
A 60hp four-stroke motor is efficient, but at cruising speed (18–22 knots), it burns 2–3 gallons of gas in 30 minutes.
With local fuel prices often around $6.00 per gallon in island areas, that’s:
Fuel Cost (30 minutes): $12–$18
Maintenance – Keeping It Running
Saltwater is brutal. Even a brand-new outboard needs:
- Oil & filter changes
- Lower unit oil changes
- Water pump impeller replacements
- Corrosion protection
When you spread these costs over the year, they add up to about $2.50–$5 for each 30-minute trip.
Boat Wear & Tear
The hull, seats, controls, safety gear—all take a beating from sun, salt, and wave action. Repairs, repainting, and replacements work out to about $2.50–$4 per 30-minute trip.
Motor Replacement Fund
A commercial 60hp four-stroke costs around $10,000 USD and, with daily use, might last 3–4 years before needing a major rebuild or replacement. That’s about $3–$4 per 30-minute trip just to save up for the next engine.
Insurance, Licensing & Safety Gear
Life jackets, radios, flares, fire extinguishers, plus legal licensing—spread over a year, these run about $1.50–$2.50 per half-hour trip.
