In the boat purchasing process, listings often highlight the hull price; the engine is either not included or referred to as "standard equipment." However, choosing the right engine is a financial decision that directly impacts the boat's cost and extends over many years. In this guide, we address engine purchase costs, annual maintenance expenses, and the total cost of ownership for the first year with concrete figures based on 2026 market conditions.
Engine Cost: An Item to Add to Your Boat Budget
Most boat buyers view the engine as a small addition to the hull cost. In reality, for a mid-range boat, the engine cost can reach 30% to 60% of the hull price. The table below shows the estimated price ranges for the most preferred outboard marine engines in the Turkish market for 2026. Figures are dependent on the exchange rate; we recommend checking product pages for current prices.
| Brand | Model | Power | Estimated Price Range (2026) |
|---|---|---|---|
| Mercury | F40 ELPT EFI | 40 HP | 450,000 – 560,000 TL |
| Mercury | F80 ELPT EFI | 80 HP | 750,000 – 930,000 TL |
| Mercury | F115 EFI | 115 HP | 950,000 – 1,180,000 TL |
| Mercury | F150 EFI | 150 HP | 1,200,000 – 1,560,000 TL |
| Mercury | F200 CMS | 200 HP | 1,600,000 – 2,050,000 TL |
| Yamaha | F40 FETL | 40 HP | 420,000 – 530,000 TL |
| Yamaha | F115 XCA | 115 HP | 900,000 – 1,120,000 TL |
| Yamaha | F150 XCA | 150 HP | 1,150,000 – 1,430,000 TL |
| Honda | BF40 LRTU | 40 HP | 400,000 – 495,000 TL |
| Honda | BF115 XU | 115 HP | 860,000 – 1,070,000 TL |
There is a 10–15% price difference between brands in the same HP class. In the long run, what is decisive is not the purchase price but the extent of the service network, the speed of spare parts access, and fuel efficiency.
Annual Maintenance and Spare Parts Costs
The engine is the only major recurring expense item on a boat. When maintenance is neglected, small malfunctions turn into large repair bills. The items you will encounter in the annual maintenance of a standard 4-stroke outboard engine are as follows:
Periodic Maintenance (Every 100 Operating Hours or Once a Year)
- Engine oil + oil filter: 4,000 – 9,000 TL
- Fuel filter: 1,500 – 4,500 TL
- Impeller (water pump kit) — once every 2 years: 5,000 – 13,000 TL
- Anode (zinc) kit — once a year in saltwater: 2,000 – 6,500 TL
- Spark plug set — once every 2–3 years: 2,500 – 6,000 TL
- Labor (service): 5,000 – 12,000 TL
Annual total estimated: 25,000 – 60,000 TL — varies depending on engine power and intensity of use. You can check our collection page for Mercury spare parts prices.
Contingency for Unexpected Malfunctions
Experienced boat owners add a contingency for unexpected malfunctions of 3–5% of the engine's purchase price to their annual budget. For a 1,000,000 TL engine, this means 30,000–50,000 TL. Marine conditions — saltwater, humidity, sudden load changes — necessitate this allowance. For quick intervention in case of a malfunction, you can check our technical service page.
First Year Total Cost of Ownership
The following example shows the cost distribution for the first year for a 19-foot fiberglass boat + Mercury F115 EFI combination.
| Item | Estimated Amount |
|---|---|
| Boat hull (19 ft, without engine) | 1,800,000 TL |
| Mercury F115 EFI engine | 1,050,000 TL |
| Installation and commissioning | 15,000 – 25,000 TL |
| First year periodic maintenance | 30,000 – 45,000 TL |
| Insurance (boat + engine) | 25,000 – 50,000 TL |
| Marina / mooring fee | 40,000 – 120,000 TL |
| 1st Year Total (estimated, excluding fuel) | 2,960,000 – 3,090,000 TL |
It should be noted that fuel is not included. With a 115 HP engine and heavy use, monthly fuel expenses can range from 15,000–40,000 TL.
Impact of Engine Choice on Long-Term Costs
Spare Parts Accessibility
Mercury and Yamaha are the brands with the widest spare parts network in the Turkish market. Mercury spare parts and marine engine spare parts are readily available in stock, while for lesser-known brands, delivery times can exceed 2–4 weeks — a period that renders your engine unusable.
Fuel Efficiency
Modern EFI engines consume 15–25% less fuel compared to older generation carbureted engines in the same HP class. Over five years of use, this difference can recoup 30–50% of the engine's purchase price in fuel savings.
Resale Value
Boats with Mercury, Yamaha, and Honda engines find buyers faster in the second-hand market and have a positive impact on the selling price. An engine with a regularly maintained service history acts as an assurance for the buyer. You can use our online service tracking system to keep your service records in order.
