The Mercury SeaPro 250hp is a robust 4.6-liter V8 outboard built for commercial reliability and power. Producing 250 horsepower with ease, this engine provides the torque and durability needed for demanding operations, yet it remains one of the lightest and most fuel-efficient in its class. Constructed with heavy-duty components and designed for easy maintenance, the SeaPro 250 works hard every day – ideal for mid-sized workboats and commercial fishing vessels where consistent power and low operating costs are paramount.

4.6L V8 SeaPro engine (250hp) – its large displacement delivers more torque and less strain, extending engine life under commercial duty cycles.
Class-leading displacement & tough build – provides excellent mid-range punch for hauling heavy loads and fast acceleration when boats are loaded down.
Reinforced components & gearcase – engineered to withstand harsh conditions and continuous operation with minimal maintenance, exceeding typical 250hp demands.
Excellent power-to-weight ratio – lighter than many competitor models, improving boat handling and saving fuel for the operator.
Superior corrosion protection & filtration – multi-layer coatings and high-capacity filters safeguard the engine in tough marine environments, ensuring reliable daily performance.

Mercury’s SeaPro 250hp outboard is all about delivering dependable power in a compact, efficient package that commercial operators can trust. Sharing the same 4.6L V8 platform as its 300hp sibling, the SeaPro 250 benefits from the high-displacement design, allowing it to run cooler and with less strain when pushing vessels at 250hp output. The result is a 250hp workhorse that provides excellent thrust and acceleration for its class – whether you’re outfitting a work boat, a fishing charter vessel, or a utility craft, this engine offers the muscle needed to get the job done with minimal fuss.

Durability is at the forefront of the SeaPro 250’s design. Its internal components – from the rugged powerhead to the stainless steel crankshaft and gearcase – are purpose-built to handle the rigors of daily use in saltwater and freshwater alike. Mercury validates these engines at duty cycles far beyond recreational use to ensure they can run long hours with confidence. Additionally, the SeaPro 250 is one of the lightest engines in its class, meaning less weight on the transom, improved fuel economy, and easier planing. This reduced weight translates directly to fuel savings and better handling – critical advantages for commercial operations where efficiency matters.

The SeaPro 250hp also incorporates Mercury’s advanced engineering for easy maintenance and smart operation. The engine features a high-output alternator capable of supporting onboard electrical systems, as well as a top-cowl service door for quick oil checks. Mercury employs superior anti-corrosion measures – a multilayer paint coating, high-strength alloys, and water-separating fuel filters – that protect the engine from wear despite continuous marine exposure. With extended maintenance intervals, this engine is easy to own and ready to work when you are.

Ideal use cases: Mid-sized commercial vessels (approximately 6–8 meters), including crew transfer boats, commercial fishing craft, and utility vessels that need reliable daily power around 250hp. The SeaPro 250 provides stability and economy for fleets where every dollar and every hour on the water count.
Recommended for: Fleet operators and professionals seeking a balance of strong performance, fuel efficiency, and unwavering reliability. The Mercury SeaPro 250hp inspires confidence in sectors such as harbor services, aquaculture, and river operations – anywhere a durable 250hp engine is required to work hard on every run.
