Scorpion 377 Sterndrive Provides Unmatched Performance Proving Itself a Viable Power Source for High Performance Bass Boat Market
Bryant Enterprises of Maryville, TN and Mercury Racing have
teamed up to develop a high performance Stroker bass boat powered by the Mercury
Racing Scorpion 377 sterndrive engine. The innovative combination of a 350 h.p.
small-block V-8 sterndrive in a 21-foot bass boat has netted very positive
results, providing unmatched performance with the Scorpion 377 sterndrive
proving itself as a viable power source for the high performance bass boat
market and is one low-emissions alternative to traditional 2-stroke performance
outboards.
The experimental Stroker/Mercury Racing sterndrive package delivers incredible
stability and handling. The use of a sterndrive engine package carries the
weight well forward, which contributes to the enhanced stability. The wide, 94
*-inch beam makes the hull a good candidate for heavier sterndrive power. Chine
walk is minimal with power steering, standard on the Scorpion 377, providing
very light, responsive steering and control. The rig, capable of reaching 100
m.p.h. speeds, features a prototype Mercury Racing Bravo One drive (not yet
available to the public) that is two inches shorter than a standard Bravo One
drive.
The race-proven Scorpion 377 is smaller and lighter than larger displacement big
blocks, yet provides comparable performance. It’s compact size and high
power-to-weight ratio enhances its versatility. In fact, the engine is the power
of choice for the American Power Boat Association’s (APBA) Offshore Pro Series.
Powerboat racing’s answer to the automotive IROC series, APBA’s One Design V
class features 24-foot canopied Armada V-bottom race boats powered by a single
Mercury Racing Scorpion 377 engine coupled to a Bravo One drive.
The Scorpion’s good looks conceal its wicked personality. Mercury Racing
technicians blueprint this handcrafted engine, built on a 350 cubic inch GM
block, by first increasing the stroke for an additional 27 cubic inches of
displacement. The increased displacement, along with specialty engine components
including a high-lift hydraulic camshaft, stainless steel intake and exhaust
valves, balanced forged-steel crankshaft and lightweight aluminum alloy pistons,
enhances power and torque throughout the engine’s operating range. Fuel
distribution is handled by a multiport electronic injection system developed by
Mercury Racing.
