Mercury Marine’s 4.6 liter V8 outboard platform is sort of a tree with many branches. From the basis V8 4 Stroke engine, many types of outboard spring to cowl the various niches of marine propulsion: from luxury-performance Verado, to the industrial Sea Professional lineup, to the Professional XS event bass engine.

And naturally, Mercury Racing, the department from which the brand new APEX 360 outboard comes from.

Mercury Racing, a separate division of Mercury Marine, builds the R sequence of outboards for performance-oriented shoppers, plus efficiency sterndrives, in addition to manufacturing refined propellers, creating particular lubricants and creating a bunch of elements and equipment that serve efficiency boaters. It’s about the one participant within the high-performance propulsion and elements and equipment house. The brand new APEX 360, stylized as APX on the cowl, confirms that. Simply as there is no such thing as a different marine engine maker like Mercury Racing there is no such thing as a different outboard like this one in the marketplace.

“It is a, ‘racing competitors,’ engine,” asserts, Stuart Halley, Mercury Racing Normal Supervisor. That’s to tell apart Apex sequence outboards from Mercury Racing’s high-performance shopper choices. So, what’s the diff?

The 360 APX is particularly meant to energy Formulation One tunnel boats on the UIM F1 H2O World Championship. It’s only obtainable to certified race groups. Guarantee? There’s none. It additionally boasts a 12-inch midsection, excellent for tunnel boats, however not a lot for a middle console or runabout. It’s rated at 360 propshaft horsepower, redlines at 7000 rpm and the 12-inch midsection options integral trim and raise.

The 360 APX is generally aspirated, retains its double overhead cam/four-valve structure and the compression ratio is elevated from 10:1 to 11:1. The powerhead is fitted with a short-runner consumption manifold mated to a cold-air induction system vented by means of the cowl. The engine calibration is modified to take full benefit of the powerhead modifications. The 360 APX makes use of a 24-volt starter for sooner dock-side beginning in competitors. The above water exhaust gives unrestricted stream, but additionally ensures race followers hear race noise. Moreover, it produces 90% decrease emissions than present two-stroke racing engines. It’s notable that Union Internationale Motonautique (UIM) President, Dr. Raffaele Chiulli, believes this engine exhibits the race organizations dedication to lowered emissions. Halley posits that between the engines effectivity, and its capacity to burn premium pump gasoline as an alternative of race gasoline, it’ll markedly decrease race groups gasoline payments.

The 12-inch midsection is all-new and designed particularly for Formulation 1 tunnel boat purposes, with a structural moist sump driveshaft housing and built-in energy trim and energy raise with distant pumps. An overdrive spur gearset between the crankshaft and the gearcase will increase the enter shaft velocity to the gearcase to match that of the present 9600-RPM two-stroke race engine, and produces the left-hand propeller rotation desired for Formulation 1 circuit racing. The overdrive gears accommodate a number of gear ratios, so groups can choose the ratio that most closely fits every specific race.

Another special feature is the above water exhaust that ensures race fans get the sound of a racing outboard.

Halley let on that Apex is a reference to a the place a driver in circuit racing is normally looking—to the apex of the flip. That it serves as a double-entendre in branding the 360 APX as on the pinnacle of mission-specific design makes it an apt moniker for this new racing competitors outboard. First in a sequence, it slated to be obtainable late fall of 2020.
