Mercury 75 HP SeaPro Electric Start Steering Trim Tilt CT Long Shaft Outboard Motor

The Mercury FourStroke 75 ELPT EFI CT SeaPro is a 4-stroke outboard marine engine designed for commercial fishing boats, rental tour boats, water taxis, and high-use marine vessels that require a long shaft, with 75 HP / 56 kW and a 2064 cc 4-cylinder engine. Thanks to its Command Thrust (CT) gearcase system, it has the large gearcase and propeller of an engine block from a higher class. The SeaPro series is Mercury's specially developed series for commercial and high-use outboards. Enhanced durability, SmartCraft integration, and long service intervals are optimized for the needs of commercial operators.

FourStroke 75 ELPT EFI CT SeaPro Series Features and Technology Advantages

SeaPro engines aim for long life in saltwater environments with a reinforced cooling system and increased anode protection compared to standard FourStroke series. The SmartCraft gauge system allows for fleet-specific engine monitoring.

• 4-Cylinder Engine (2064 cc): SeaPro engines aim for long life in saltwater environments with a reinforced cooling system and increased anode protection compared to standard FourStroke series.
• Long Shaft (508 mm (20")): The propeller operates at optimum depth with the correct transom height.
• SeaPro Durability Package: Reinforced cooling, increased anode protection, and long service intervals.
• Command Thrust (CT) Gearcase: The large gearcase and propeller of an upper engine block — high torque at low RPMs and powerful thrust capacity.
• Electric Start: Instant engagement with a key or button — comfortable and quick starting.
• Power Trim & Tilt: Adjust trim angle with a button during navigation — fuel efficiency optimization; full motor lift with tilt.

Frequently Asked Questions

Why is the Mercury SeaPro 75 HP recommended for commercial use?

The SeaPro series offers a reinforced cooling system and increased anode protection compared to standard FourStroke engines. SmartCraft integration facilitates fleet management and engine monitoring. Long service intervals reduce operational costs.

What does the SmartCraft system provide in SeaPro engines?

SmartCraft transmits engine status, fuel consumption, temperature, and hourly operation data to a digital display. In multi-engine configurations, each engine can be monitored separately. The early fault warning system prevents unexpected malfunctions.

What are the maintenance intervals for SeaPro engines?

SeaPro engines are designed for long service intervals. Oil changes should be performed according to manufacturer recommendations. In saltwater use, freshwater flushing after every use and end-of-season anode inspection are mandatory.

Which boat and brand models are compatible with the FourStroke 75 ELPT EFI CT SeaPro?

Mercury outboards 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 transom height of 508 mm (20") and the maximum engine power approved by the manufacturer. You can get compatibility confirmation from Clever Marin by sharing your boat model.
