Please Share!

Mercury Racing have today officially announced their new 360 APX motor that has been built for competition in the UIM F1H2o series.

The 360 APX is based on a modified version of the Mercury Racing 300R 4.6-liter V8 powerhead.

The engine is normally aspirated and retains its dual overhead cam/four-valve architecture. The compression ratio is increased from 10:1 to 11:1 and peak rpm is boosted from 6400 RPM to 7000 RPM.

The 12-inch midsection is all-new and designed specifically for Formula 1 tunnel boat applications, with a structural wet sump driveshaft housing and integrated power trim and lift with remote pumps.

An evolved version of the Mercury Racing Super Speed Master (IV SSM) outboard gearcase is direct-drive with no neutral or reverse shifting. Above-water exhaust offers unrestricted flow and produces an exciting tone for racing fans.
