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. Read more
“M for Mercury! M for Miss GEICO! M for Magnificent!” Those were the first words from Gary Goodell upon my congratulatory call to him Monday morning regarding Miss GEICO’s convincing win last weekend in Port Huron. OPA’s bracket race rule, with a speed cap of 135 mph, puts a spotlight on driving skill and acceleration. Miss GEICO’s QC4v 1650’s are unparaled when it comes to acceleration. Time in and out of the turns were the deciding factor in this bracket race.
“The 1650s ran flawlessly. They respond and pull like no other. They are a blast to drive,” said Miss GEICO driver Marc Granet. “We enjoyed having Mike Griffiths (Mercury Racing Product Integration Manager) and (Mercury Racing Engineering Tech) Johnny Bauer with us for the weekend,”
Marc said. “It was an insightful weekend. We learned alot. The team is continuing to gel. The 1650s continue to impress us – and our competitors,” Marc exclaimed. Marc said there was one moment when they were concerned about the engines. “We we slowing down upon completing the race and I started to hear an odd rumble sound. Scotty [Begovich] heard it too. It was a few seconds later before we realized it was the roar of hundreds of fans along the Sarnia, Ontario side of the St. Clair river. The response was overwhelming!,” said Marc. Read more
