The V8 300R outboard is tuned up with Mercury Racing components to deliver blistering speed, crisp throttle response, thrilling top-end power and confident control – the perfect match for a variety of high-performance boats. Midsection and gearcase options, as well as tie-bar and steering choices, allow the creation of a near-custom V8 300R configuration to provide optimal performance and ease of installation for most applications, including repower upgrades.

 

Years of Mercury Racing engine-tuning experience have been applied to the V8 300R outboard model. A short-runner intake manifold and high-lift intake camshaft designed specifically for the V8 300R combine to produce quick acceleration. The V8 300R is equipped with stainless steel valves and an oil cooler to better manage engine heat. To maximize top speed and propping options the wide-open throttle (WOT) operating range is extended to 5800-6400 rpm.

 

Mercury Racing Advanced MidSection (Racing AMS) features Digital Throttle and Shift (DTS) controls & Mercury power steering. Heavy-duty guide plates and engine mounts stabilize the outboard for enhanced high-speed handling on high-performance, stepped-bottom center-console boats. An optional rear tie-bar bracket integral to the Racing AMS provides a strong, ultra-light mounting point for precision steering on catamaran and other ultra-high-speed applications.

 

Mercury Racing Conventional MidSection (CMS) features solid lower mounts, stiffer upper mounts and an integral Tri-Ram trim system. It’s available exclusively in a 20-inch shaft length with the Torque Master gearcase for tournament loaded bass boats, or the Sport Master gearcase for ultra-high-speed bass or performance flats boats.
