The Mercury FourStroke 250 L is a 4-stroke outboard marine engine designed for medium to large fiberglass, aluminum, or composite boats that require a long shaft. It features a 250 HP / 184 kW, 4600 cc V8 (8 Cylinder) engine. With its 4600 cc V8 EFI FourStroke engine, the FourStroke 250 L offers a balance of high power and fuel efficiency for large boats. This model, part of Mercury's main production line, stands out with its extensive service network and reliability advantages.
FourStroke 250 L Series Features and Technology Advantages
The V8 engine, with its wide power band and EFI electronic injection, delivers high torque at low RPMs and stable power at high RPMs. Its stainless steel propeller and external fuel system are suitable for large boat use.
- V8 (8 Cylinder) Engine (4600 cc): The V8 engine, with its wide power band and EFI electronic injection, delivers 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 Fuel Injection: Easy cold-weather starting 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 while cruising — optimizes fuel efficiency; tilt raises the engine completely.
- External Floating Fuel System: Connection for a large capacity external tank — range is determined by user needs.
Long Shaft — Which Boat Type Is It Suitable For?
The long shaft (508 mm (20")) is suitable for the vast majority of inflatable, aluminum, and fiberglass boat models. For boats with a transom height of 381 mm, a short shaft model should be preferred.

Maintenance and Longevity
4-stroke Mercury engines operate smoothly for many years with regular oil changes and end-of-season maintenance protocols. The impeller of the water-cooled system should be checked every 100 hours or every two seasons. In saltwater use, freshwater flushing is mandatory after every use.

Frequently Asked Questions
What boat size is the Mercury FourStroke 250 HP engine suitable for?
250 HP power can be suitable for different sizes depending on the boat's 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 high altitudes, consistent power output, and lower fuel consumption compared to carbureted alternatives.
What are the Mercury FourStroke maintenance intervals?
Oil change at the first 20 hours, then every 100 hours or once a season. Impeller check every two seasons. In saltwater use, freshwater flushing is mandatory after every use. End-of-season fuel system protection is recommended.
Which boat and inflatable boat brands are compatible with the FourStroke 250 L?
Mercury outboard motors 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.
