2026 Mercury Racing 200 APX

A New Breed
The Mercury Racing 200 APX is a powerful V6 fourstroke outboard designed for UIM F2 and APBA OPC tunnel boat racing. Rated at more than 200 horsepower, the 200 APX outboard offers racers a very durable powerhead and the latest in four-stroke engine technology, while reducing exhaust emissions by 90 percent compared to the legacy two-stroke competition outboards.

Overdrive
How we make power: A 3.4-liter V6 powerhead and deep-breathing double overhead cam/four-value architecture is tuned to wind up to 6800 rpm. Compression ration is boosted to 11:1. A heavy dose of dense, cool air is ducted directly to intake.

Gearcase
An evolved Mercury Racing Super Speed Master (IV SSM) outboard gear case is direct-drive with no neutral or reverse shifting.

Exhaust Emissions
The four-stroke mercury racing 200 APX reduces exhaust emissions by 90 percent compared to a two stroke racing outboard of similar performance. Unlike those two-stroke motors, the 200 APX will require very little maintenance between races, and is designed to perform on 91-octance (98 RON w/ E10 max) pump fuel

A V6 To Go
This potent V6 outboard features a 3.4-liter powerhead with deep-breathing double overhead cam/four-valve architecture. For competition, the compression ratio is boosted to 11:1 and peak RPM pushed to 6800. A lightweight carbon fiber cowl incorporates forced cold air induction. This engine is designed to perform on 91-octane pump gasoline fuel. The 200 APX features a precise digital throttle control, and is equipped with a 24-volt starting system.
