2021 Mercury Racing 400R Twin Pair — 370 Hours, Complete Controls & Accessories

Condition report

A 2021 twin pair of Mercury Racing 400Rs with 370 hours, sold with complete controls and accessories per the owner. The white cowlings carry the blue-R “400 R” badges, “Racing 400” side graphics and VERADO top badges — these are the L6 Verado-platform Racing motors, and the under-cowling shot shows the supercharged L6 powerhead with its large Mercury-logo intercooler.

The pair is photographed mounted on a white centre-console (boat and trailer are context, not part of the sale) on black SeaStar Xtreme jack plates, with white midsections and silver lower units; no props are fitted in the photos. Two shots show both top cowlings off the motors, leaning against a car indoors — the powerheads underneath are the story there.

To keep the record straight: this pair is a separate set from the 2021 Verado 400 L6 twin pair in this same batch — that listing is standard Verado 400s sold as engines only; this is the Racing 400R pair at 370 hours with the complete controls package.

Overview

The 400R takes the supercharged L6 Verado platform and turns it Racing: higher RPM ceiling, sport calibration and the hardware to run hard in offshore performance boats. A matched 2021 pair at 370 hours with complete controls and accessories is the repower core for a serious centre console without the hunt for rigging afterwards.

Compare the batch honestly: engines-only Verado 400 pair (warranty-led) versus this Racing pair (controls-led, 370 hours). Same model year and shaft length, two different answers — pick the one your boat needs, or talk to us about both.

What’s included

• Complete controls and accessories (owner-stated)

Ideal for

Performance centre consoles on twin 20-inch transoms repowering to Racing power with the rigging included, and 400R replacements for existing Racing rigs.

Compatibility notes

• 20-inch shafts — match to your transom and jack-plate setup (photographed on SeaStar Xtreme jack plates, which are boat equipment in the context shots).
• No propellers are fitted in the photos — confirm prop requirements with us for your hull.
• Confirm your boat's capacity plate: never exceed the maximum rated horsepower.
