Strong and Durable: Introducing the Mercury Racing Advanced Racing Core Midsection

500R_ARC_2-BLOG.jpgSpeed and power on the water require precise control and rugged durability. The new Mercury Racing Advanced Racing Core (ARC) midsection, exclusive to the Mercury Racing V8 500R outboard, is the strongest, stiffest and most-durable midsection ever created by Mercury Racing.

The ARC features a new transom plate designed to be stronger than previous Racing midsections to harness the power of the new 500R outboard. Seven mounting holes accommodate three inches of vertical adjustment, twice the adjustment range available with the six-hole 450R transom plate.

Precision Trim
The trim system features two main hydraulic rams plus two new booster rams for added trim authority under full load, and the speed of the trim adjustment, similar to the 450R, is slowed down to permit very fine resolution for more-precise trim adjustment at high speeds. Precision-fitted heavy-duty guide plates and stiffened engine mounts are tuned to stabilize the engine for enhanced high-speed handling.

Stout Steering
A new steering cylinder delivers almost 20 percent greater steering force to better manage the higher torque of the 500R. The steering arm, steering tube and steering cylinder are also new and 20 percent stronger, with an upgraded tube material changed from aluminum to stainless steel.  An optional rear tie-bar bracket integral to the ARC provides a strong, ultra-light mounting point for rock-solid precision steering on catamaran and other ultra-high-speed applications.

The Mercury Racing 500R is covered by a three-year limited factory warranty with up to five additional years of Mercury Product Protection extended factory warranty available. Learn about the Mercury Racing Wide Open lifestyle and all Mercury Racing high-performance products at
