2020 Mercury Racing 450R — ECU-Verified 630 Hours, 30″ Right-Hand, Warranty to 09/2028
2020 Mercury Racing 450R · 629.8 ECU hours · 30″ right-hand · supercharged V8 · warranty to 09/2028
Condition report
Used 2020 Mercury Racing 450R in white with gold and black graphics, photographed on the stand as offered. The headline number on this motor is not a guess: its ECU run-history printout is in the gallery and reads 629.8 total engine hours for the starboard-inner module. The RPM profile behind that total is the real story — 230.8 hours at 0–784 RPM and 215.1 hours at 785–1704 RPM, with just 0.3 hours at 5400–6199 RPM and zero hours at 6200+. This is a gently-run 450R, not a motor that has lived at the limiter.
Under the cowling the supercharged 4.6L V8 presents clean and complete, with the Mercury Racing maintenance-schedule sticker in place and the AMS midsection tidy. Honest wear is where you would expect it on a working performance motor: black scuff and paint wear on the lower unit and skeg, and barnacle traces at the transom bracket — both visible in the photos and priced into the listing. Warranty coverage runs until 09/2028.
Mercury Racing’s 450R is the supercharged flagship of the Racing line — a 4.6-litre V8 with a Mercury Racing supercharger, built for centre consoles and performance boats that cruise fast and run hard offshore. This 2020 unit is a 30-inch, right-hand rotation single, and the seller notes the shaft length can be configured to the length your setup needs — ask our team when you enquire.
Looking for the other rotation or a matched set? We also stock a 2022 Mercury Racing 450R in 30-inch left-hand and a twin set of 2020 Mercury Racing 450Rs on 20-inch shafts, so single, counter-rotating and twin 450R repowers are all covered from one yard.
What’s included
This listing is for the outboard motor itself. No propeller is fitted in the photos and none is claimed — rigging, controls and propellers are available through our team and are not included unless stated. Every Apex engine is compression tested and supplied with warranty; this unit additionally carries warranty coverage to 09/2028 as listed.
Ideal for
Single-engine performance centre consoles, stepped-hull offshore boats and go-fast repowers on a 30-inch transom that want supercharged 450R thrust with an ECU-documented, gently-run history — or the right-hand half of a counter-rotating pair alongside our 2022 left-hand 450R.
Compatibility notes
- Confirm your transom height and shaft length before purchase — our team will verify fitment for your hull.
- Modern four-strokes and digital controls may need matching rigging, harnesses or gauges; ask for a complete rigging quote.
- Twin and multi-engine sets are sold as matched sets unless the listing says otherwise.
Delivery
Engines are crated, fully insured, and shipped nationwide within the US in 3–5 business days. A 35% deposit reserves the engine; the balance is due before dispatch. Local pickup in Fort Lauderdale, FL is welcome.

Will it fit your boat?
