Mercury 200 HP Electric Start, Steering, Power Trim & Tilt, Long Shaft Outboard Motor

The Mercury FourStroke 200 L is a 4-stroke outboard marine engine designed for medium and large fiberglass, aluminum, or composite boats requiring a long shaft, with a 200 HP / 149 kW and 3400 cc V6 (6 Cylinder) engine. The FourStroke 200 L with its 3400 cc V6 EFI FourStroke engine offers a balance of high power and fuel efficiency for larger boats. As a core model in Mercury's product line, it stands out with its extensive service network and reliability advantages.

FourStroke 200 L Series Features and Technology Advantages

The V6 engine provides a wide power band and, with EFI electronic injection, offers high torque at low RPMs and stable power at high RPMs. The stainless steel propeller and external fuel system are suitable for large boat use.

• V6 (6 Cylinder) Engine (3400 cc): The V6 engine offers a wide power band and, with EFI electronic injection, provides high torque at low RPMs and stable power at high RPMs.
• Long Shaft (508 mm (20")): The propeller operates at optimal depth with the correct transom height.
• EFI Electronic Injection: Easy cold start and consistent power output across the entire RPM range.
• Electric Start: Instant activation with a key or button — comfortable and quick starting.
• Electric Trim and Tilt (Power Trim & Tilt): Adjust trim angle with a button during navigation — optimizes fuel efficiency; tilt allows the engine to be fully raised.
• External Flooded Fuel System: Connection for a large capacity external tank — range determined by user needs.

Long Shaft — What Type of Boat Is It Suitable For?

The long shaft (508 mm (20")) is suitable for the majority of inflatable boats, aluminum, and fiberglass boat models. For boats with a transom height of 381 mm, a short shaft model should be preferred.

Frequently Asked Questions

What boat size does the Mercury FourStroke 200 HP engine fit?

200 HP power can fit different sizes depending on boat weight and type. General rule: 15–20 kg boat weight per HP. Always check the maximum engine power recommended by the boat manufacturer.

What advantage does the EFI system offer over a carbureted engine?

EFI (Electronic Fuel Injection) does not require a primer pump or choke adjustment. It provides reliable starting in cold weather and at high altitudes, consistent power output, and lower fuel consumption compared to carbureted alternatives.

What are the maintenance intervals for Mercury FourStroke?

Oil change at the first 20 hours, then every 100 hours or once per season. Impeller checked every two seasons. In saltwater use, freshwater flushing is mandatory after each use. End-of-season fuel system protection is recommended.

Which boat and inflatable boat brands are compatible with the FourStroke 200 L?

Mercury outboard engines are compatible with many fiberglass, aluminum, and inflatable boat models thanks to their universal transom clamp or transom mounting system. The only criteria are your boat's 508 mm (20") transom height and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
