V MAX HPDI - Features & Benefits

The Engine Control Module regulates the HPDI System, to ensure superior power, fuel economy and reliability. Here's how HPDI works. Six sophisticated sensors help the microcomputer optimize ignition timing and air/fuel mixture. Fuel is drawn through the fuel pump and vapor separator, then pressurized by the twin high-speed fuel pumps – to 1,000psi in our new-generation 3.3L HPDI. Proven and reliable internal-opening fuel injectors distribute the fuel to each individual cylinder enhancing fuel distribution for increased power and greater fuel economy.
3.3L Unique Features & Benefits

A powerful, 3.3-Liter, 204 Cubic-Inch Engine. The 76° V-block design is compact, with added torque for greater acceleration.

Special Heat Treated Crankshaft and Connecting Rods enhance durability for long term engine life.
New, Special Ion-Plated Top Piston Ring enhances durability and delivers up to 20% more oil economy. The oil bypass groove on the bottom piston ring delivers the precise amount of oil to the top ring.
Fuel is Routed through a water/fuel separator, a vapor separator tank, twin high-speed fuel pumps and fuel rails, then delivered through 6 independent internal opening fuel injectors.
Water Inlets have been front-mounted and lowered on the V MAX® 300, 250. 225 and 200hp models for increased cooling, efficiency, and optimal set up.
Water Cooled Intake Crankcase This unique feature increases intake air density for added horsepower on the Z300 and VZ300.
Twin High Speed Fuel Pumps pressurize fuel at 1,000psi for outstanding performance and fuel economy on 3.3 Liter HPDI models.
The unique, Concave-Shaped Skeg Design on the new V MAX® 3.3L models dramatically reduces steering torque, enabling the lower unit to track straight during acceleration, top-end and deceleration. This new lower unit was engineered to maximize performance on today's bass boat hull designs.
Strong, Forged Pistons add durability. Aluminum alloys are compressed in molds under extreme pressure, resulting in a much stronger piston.
The High Output Alternator on HPDI 3.3-liter models delivers an incredible 37 amps of charging power at only 1000 rpm and a full 50 amps at speed. The all new V 76° block is compact and designed to maximize torque, power, fuel economy and durability.
