Mercury SeaPro 200-350hp

Name: Mercury SeaPro 200-350hp
Brand: Mercury Marine

Mercury SeaPro commercial outboards from 200 to 350 hp (V6, V8, V10) with commercial calibration, heavy-duty gearcase, four serviceable anodes and Adaptive Speed Control.

Description

The Mercury SeaPro 200–350hp range covers commercial-duty V6 (200 hp, 3.4L), V8 and V10 (350 hp) outboards. Commercial calibration provides strong torque at lower rpm, reducing engine stress under hard use.

Key features

Corrosion resistance from aluminum alloys and coatings, with four serviceable anodes including one in the cylinder block
Heavy-duty gearcase validated at three times the lifespan of a recreational gearcase; new rugged gearcase on the V10
Adaptive Speed Control maintains rpm under changing load without throttle adjustment
Idle charge battery management
Top-cowl access door for oil checks; gearcase oil drained from the torpedo
V8 and V6 models 15–30% quieter than a leading four-stroke competitor; V10 28% quieter at cruise (maker data)
Conventional MidSection (CMS) 200–300 hp models are the lightest in their class

Controls and integration

Advanced MidSection (standard on V10 350 hp, available on V8 300 hp) supports Joystick Piloting for Outboards (JPO) for multi-engine setups and Mercury Electric Steering, which uses over 50% less power than the previous electro-hydraulic system
Digital Throttle & Shift standard on V10 and V8 AMS, available on V8 and V6 CMS
Active Trim and VesselView Mobile

Applications

Commercial workboats and professional operators requiring high duty cycles.

Everllence 35/44DF CD Dual-Fuel GenSet

Medium-speed dual-fuel GenSet with 560 kW per cylinder output and up to 85% lower methane slip than current industry standards, based on the 35/44DF CR and 32/44CR, prepared for methanol upgrade.

Equipment

Alfa Laval

Fluidic Air Lubrication

Alfa Laval fluidic air lubrication (OceanGlide) reduces hull friction with an even air layer over the flat bottom, generated by fluidic oscillators with few compressors, cutting propulsion power and fuel use.

Component

Accelleron

MXP

Accelleron MXP (Marine auXiliary Power) turbochargers for small-bore, medium-speed marine auxiliary engines from 600 kW to 2,000 kW, with HFO-capable turbine, VTG versions and self-service maintenance app.
