Mercury 500 HP SeaPro V12 Electro-Hydraulic Steering Trim and Tilt Outboard Motor

The Mercury V500 SeaPro V12 is a 4-stroke outboard marine engine designed for commercial fishing boats, rental tour boats, water taxis, and high-use marine vessels that require an ultra-long shaft. It features 500 HP / 372 kW and a 7600 cc V12 (12-Cylinder) engine. The SeaPro series is Mercury's specially developed line of outboard motors for commercial and high-use applications. Enhanced durability, Smart Craft integration, and extended service intervals are optimized to meet the needs of commercial operators.

V500 SeaPro V12 Series Features and Technology Advantages

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

• V12 (12-Cylinder) Engine (7600 cc): SeaPro engines aim for long life in saltwater environments with a reinforced cooling system and increased anode protection compared to standard FourStroke series.
• Ultra-Long Shaft (635 mm (25")): Propeller operates at optimum depth with the correct transom height.
• SeaPro Durability Package: Reinforced cooling, increased anode protection, and extended service intervals.
• Electric Start: Instant engagement with a key or button — comfortable and fast starting.
• Electric Trim and Tilt (Power Trim & Tilt): Adjust trim angle with a button during cruising — fuel efficiency optimization; tilt to raise the engine completely.
• Floating External Fuel System: Connection to a large capacity external tank — range determined by user needs.

Ultra-Long Shaft — Which Boat Type Is It Suitable For?

An ultra-long shaft (635 mm (25")) keeps the propeller at an optimum depth on large yachts and professional boats with deep transom designs. Incorrect shaft selection can leave the propeller out of the water or scrape the bottom — measure transom height before installation.

Frequently Asked Questions

Why is the Mercury SeaPro 500 HP recommended for commercial use?

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

What does the Smart Craft system provide in SeaPro engines?

Smart Craft transmits engine status, fuel consumption, temperature, and hourly operating data to a digital display. In multi-engine configurations, each engine can be monitored separately. The early warning system for malfunctions prevents unexpected breakdowns.

What are the maintenance intervals for SeaPro engines?

SeaPro engines are designed for extended service intervals. Oil changes should be performed according to manufacturer recommendations. Freshwater flushing after every use in saltwater and end-of-season anode checks are mandatory.

Which boat and vessel brands are compatible with the V500 SeaPro V12?

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 635 mm (25") transom height and the maximum engine power approved by the manufacturer. You can confirm compatibility with Clever Marin by sharing your boat model.
