We are excited to unveil our concept QC4v crate engine this week at the 50th annual SEMA show. The A multitude of configurations are possible, fom basic long block form to ready to run engines. The project has to be one of our best kept secrets ever.
This is our first SEMA show and there is a lot to see. We brought an exotic supercar fitted with a turbocharged QC4v 1650 crate engine. The car is complimented with an equally exotic DCB M41-Wide Body catamaran sport boat powered by twin 1350 sterndrives.
An immaculate cutaway crate engine display shows the brilliantly engineered inner workings of the QC4v engine design. That is flanked by a complete QC4v 1350 and 8.2 Liter 520 sterndrive engine displays. A complete QC4v crate engine is featured in SEMA’s New Products Showcase.
This isn’t Mercury’s first road trip. Our late founder Carl Kiekhaefer revolutionized NASCAR from 1955-57. Mr. Kiekhaefer dominated the sport by winning 80% of the races he entered and capturing three national championships. The innovator changed the sport forever with many firsts. His crew was the first to wear matching uniforms and practice pit stops.
His Chrysler 300 race cars were fully decorated with the legendary Kiekhaefer Mercury Outboards “sponsor” logos. His was the first team to use enclosed car haulers with matching graphics. Mr. Kiekhaefer also introduced many technical innovations, such as the modern pleated paper air filter during his quest for checkered flags. NEXTEL Cup cars still use wide base rims that can trace their origin back to Mr. Kiekhaefer’s road racing R&D.
In 1990, General Motors approached Mercury Marine to produce the all-aluminum, 5.7-liter LT-5 engine for the Chevrolet ZR-1 Corvette. GM came to Mercury MerCruiser for its expertise in the design and manufacturing of aluminum engines for the marine environment. The ZR-1 was a world-class sports car in its day. The quad-cam, 32-valve V8 produced 405 horsepower at 5,800 rpm. The Wette Vette promotional project featured a ZR-1 Corvette with LT-5 powered Baja in tow. The pair were show stoppers, generating press throughout the globe.
We are very excited about our SEMA debut and the potential for automotive applications of our popular marine engines. Check back for a video feature on our opening day activities.
I just got some great news from Mike Griffiths – our resident product integration expert. Mike has been helping me dial-in an assortment of props for various applications. Mike and I tested props with anglers during Mercury’s National Walleye Tournament in Fond du Lac earlier this summer. Mike claims he is not an outboard guy, but you would never know it. It didn’t take him long to transfer his sterndrive performance boat knowledge to enhance the set-up of an average outboard walleye rig.
A number of anglers were smiling after reaping the benefits of Mike’s work on their boats. Mike provided input on weight distribution, engine height, trim tab positions and of course, props. The Bravo One XS was the star wheel for Optis; the Pro Finish Bravo I FS was more often than not the wheel of choice for Pro Verado folks.
As much fun as Mike had with the outboards, his first love is big block sterndrives. He recently did some testing with various West Coast boat builders. With the recent outboard props at his disposal – he thought why not try one with a sterndrive. The boat was a 29-foot Nordic Deck Boat with 565 power.
Mike began his test with a stock 26″ Bravo I prop on a Bravo One XR drive. The 565 turned 5380 – 5400 RPM @ 69.5 mph. Mike then grabbed one of his test props for a spin. The 27″ Bravo I FS turned 5450 RPM @ 74.8 mph; an incredible 5.3 mph speed gain! Mike is impressed – and it takes a lot to impress him. Nordic is equally impressed. I am too. It looks like Rick Mackie will be updating the Bravo I FS sell once again with a new title; Bravo I FS for Outboards…..and Sterndrives!
Give it up for the Australians and their total domination of the 2013 Water Ski Racing World Championships! The event, held in Tenerife, Spain, concluded Sunday after four rounds of racing. Mercury Racing propulsion was the power in front of all six class world champions. As you can see, conditions were more ideal for an offshore race than ski racing.
To me – running a 21 foot boat with a QC4v 1350 stuffed between the stringers would be a handful. Racing it would another thing all together.
But to ski behind that? No thanks. I can’t imagine going as fast as they do on calm water. Ski racing in big water where your tow boat is periodically airborne? Forget about it! That takes some serious skill, stamina and pure guts!
Guy Williamson, our Service Director in Australia sent me an e-mail with the outstanding results.

Congratulations to all competitors on an outstanding world championship.
It’s been a busy summer. Last week we introduced our new 520 sterndrive and our our new mobile marketing truck at the Lake of the Ozarks Shootout in Missouri. It was developed to provide recreational boaters a low-cost option for gaining access to Mercury Racing’s exclusive group of high-performance sterndrive propulsion systems. By the response we’ve received thus far, the engine package is destined to be the power behind a variety of recreational boating applications including runabouts, sport boats and cruisers. Did I mention pontoons?
Based on the 8.2L cylinder block – the 520′s cylinder bores are punched out to 4.560″ for a total of 8.6L of displacement. The larger displacement, combined with Mercury Racing cylinder heads, multiport fuel injection and an electronic throttle body results with more torque than the 525 EFI and nearly 100 additional horsepower over MerCruiser’s 430 h.p. 8.2L MAG HO. All from 87 posted octane (R+M)/2 or (91 RON) (global) pump gas!
The 520 is our first sterndrive to be backed by a two year limited factory warranty. Robust valve train components including a hardened camshaft are used for enhanced durability. Performance cam profiles, combined with larger valves, pack more air through the engine for greater power and torque. Greater displacement, combined with enhanced airflow, results in unprecedented mid-range punch and consistent pull through the engine rpm operating range.
The 520 features the same Propulsion Control Module (PCM 09) microprocessor as found on the 565 and QC4v family. In addition to digital throttle and shift control, the PCM optimizes fuel delivery and spark timing independently for each cylinder for enhanced engine running quality, performance, fuel economy, and durability.
The PCM computer also drives Mercury Racing’s exclusive Engine Guardian System. Engine Guardian monitors engine functions and indicates when parameters go out of specified range, minimizing the risk of engine damage. This “smart” technology not only detects and alerts the boater of a problem; it also processes the data and reduces power to a maximum, safe level that allows the boater to continue operation. Additionally, Engine Guardian has the ability to proactively prevent engine overheating by sensing not only engine temperature, but exhaust coolant temperature as well. By sensing engine coolant and exhaust coolant temperatures, the system can take action in advance by reducing engine power before temperature related engine damage occurs.
The PCM enabled system also features one-touch Smart Start and automatic throttle synchronization. Furthermore, it enables shadow mode for multiple engine applications, where two throttle levers can operate up to four engines.
Rigging Bits and Bytes
Although it shares some of the DNA from it’s 8.2L MAG HO cousin, the 520 uses hydraulic steering and thus it is rigged similarly to our Bravo based sterndrive product. This means boats rigged with our high performance Bravo transom will need to apply transom mounted hydraulic steering rams for the drive(s). Consumers have an option to purchase our Integrated Transom System (ITS) that includes the hydraulic steering rams for a clean, functional installation. Tie-bars are required for all multiple engine boats equipped with external hydraulic steering. Digital throttle and shift rigging is a snap when compared to the running of cables for mechanical rigs.
A total of 11 color options, including the standard Mercury Racing Blue Metallic, are available to fit virtually any style or theme.
Power to the Water:
The 520 is available with Bravo One XR, Bravo One XR Sport Master (standard and short) and Bravo Three XR drive options. The Mercury Racing Integrated Transom System (ITS) is also available. A wide variety of Mercury Racing propellers are available for enhanced performance in virtually any application.
The 520 is supported by the world’s largest marine service network of dealers and Mercury Racing’s Total Engine Application Management (TEAM) initiative. The standardized TEAM process ensures proper installation of the engine with factory specified components, providing maximum performance along with unmatched quality and durability.
