HP500 Bulldog

The 1999 HP500 Bulldog and HP525SC engine packages share all of the consumer-friendly attributes common with the new HP500EFI and proven HP500, including a one-year limited warranty, three-year limited corrosion warranty, and choice of 1.36:1 or 1.50:1 gear ratio Bravo One Drive or Bravo One Performance Drive options in either right-hand or left-hand rotation. The 500 Bulldog and all supercharged models are blueprinted. We polish crankshafts, check bearings, fit connecting rods, pistons and rings to exact tolerances. We use the highest quality specialty parts on the top end as well, including push rods, rocker arms, cams and lifters.

Supercharged MerCruisers have evolved from our experiences in racing the 1000SC on the APBA and SBI Superboat circuits. These precision-built engines feature blueprinted, race-proven components married to a high performance supercharger that produces huge torque and horsepower, all on 92 octane gas. The HP525SC continues to be the most popular supercharged propulsion package in boating today. Based on the legendary 454 cubic inch (7.4 L) cylinder block, the 525SC, with the assistance of a Weiand supercharger coupled to an aluminum intake manifold, delivers a potent 490 (365 kW) propshaft horsepower!

All 1999 MerCruiser Hi-Performance Series sterndrive models feature a thermostatically controlled, high-capacity oil cooler. The oil thermostat gets engine oil temperatures up quicker and keeps them more consistent. The Thunderbolt V ignition system, standard on all models with the exception of the 500EFI, Scorpion 377 and 900SC, delivers precise control of both idle speed and detonation.

HP500/HP500 EFI

A 502 cubic inch (8.2 L) General Motors cylinder block and rugged GM internal components are the heart and soul of the race-proven HP500 and the all-new HP500EFI. The new HP500EFI features a multi-port fuel injection system which incorporates a high-flow throttle body and tuned intake manifold developed exclusively by Mercury Racing. This, along with an advanced fuel injection system provides instant starting and smooth idling and crisp throttle response. The 500EFI's robust power band spreads torque evenly for improved throttle response across the operating range. In addition to a race-developed multi-port fuel injection system, the new HP500EFI uses an advanced Electronic Control Module that monitors a variety of vital engine conditions, including rpm levels, oil pressure, water temperature and spark timing, keeping the engine in perfect tune. High-quality specialty parts include high performance push rods, rocker arms, valves and lifters. Stainless steel tubular headers enhance engine performance and aesthetic appeal. A one-piece serpentine belt system drives engine accessories including a 60-amp (846 watt) alternator, power steering pump (idler pulley on models without power steering), circulating pump and sea pump. The one-piece belt design is easier to service and provides unsurpassed belt life.

The HP500 continues to provide flawless performance as the exclusive power of the APBA's exciting Factory V-Bottom Series. The ensemble of a hydraulic roller camshaft, Dart single plane intake manifold and Holley 800 CFM carburetor give the HP500 its renowned performance characteristics: ultra-smooth idling, instant throttle response, and unprecedented reliability. Both engines are available with 1.36:1 or 1.50:1 gear ratio Bravo One Drive or Bravo One Performance Drive options in either right-hand or left-hand rotation and are backed by a one-year limited warranty and a three-year limited corrosion warranty.
