Crusader Marine Motors

No-Vibe Mounts

Crusader’s No-Vibe mounting system offers the highest degree of adjust-ability in the industry. Larger, more robust and extremely heavy-duty, Crusader’s mounts ensure continuing perfect shaft alignment for years.

Sooner or later, however, the engine will have to be realigned as part of routine maintenance. The adjustable components of Crusader’s mounts are easy to realign because they are made of non-corrosive state-of-the-art composite materials, rather than plated steel which is subject to rust and galvanic corrosion.

The mounting system must be able to dampen and absorb vibration to keep it from being transferred to the hull through the stringer system. Crusader uses large rubber isolators to better isolate the vibration.

Crusader’s superior mounting system extends to the overall design, which positions the mounts close-in to the transmission at the mid-point, evenly distributing the weight for a stronger, more rigid hold. This position prevents movement, which would destroy the perfect alignment and vibration-free ride.

Fuel Delivery Systems

Electronic fuel injection (EFI) provides improved drive-ability, efficiency and performance. Today’s high performance EFI engines require the utmost in fuel delivery systems. Constant fuel flow to the injectors must be guaranteed, regardless of how choppy the water can get or how tight the turn. Therefore, the marine engineer is challenged to find a way to ensure fuel flow without the need for a specially designed fuel tank or other apparatus.

According to the boating application, Crusader answers this challenge with exclusive, patented fuel delivery systems: the Crusader Fuel Control Cell or Crusader Aqua Cool. Both systems ensure proper fuel filtration and fuel delivery to the injectors, regardless of the conditions

The Cooling System

Engine durability and longevity are directly impacted by the quality of the cooling system. Crusader uses a larger, brass or stainless steel water pump and a full freshwater system to cool both the engine block and the manifolds. Compare Crusader’s premium heavy-duty water pump to that of the competition. Our larger diameter impeller allows for more coolant flow.

Equate the durable, non-corrosive brass or stainless steel housing to the plastic pump used by a competitor. We have two bearings and a double lip seal for long life, versus the single bearing and single seal system of our competition. And compare our machined O-ring housing and rubber O-ring, which ensures sealing and easy service, to the paper gasket used by some. The result is a highly durable system that guarantees optimal cooling for long life.

Performance and Durability

All Crusader inboards are based on GM's famous Vortec engine blocks and feature MEFI-4, the latest in multi-port fuel injection technology.

Electronic fuel injection, combined with microprocessor-based engine management, provides significant performance benefits. The EFI engine is more responsive, with smoother acceleration and excellent turnkey starts.

Reduced fuel consumption and improved emission control is due to the precision of the engine control management system (ECM).

But the benefits of EFI don't end with performance: MEFI-4 engines are more durable and reliable.

The Engine Knock Control Sensor detects engine knock and virtually eliminates it by automatically changing the spark timing and fuel delivery. Over-speed protection automatically limits engine RPM if there is a danger of over-revving due to prop failure or cavitation.

The Speed Reduction Control reduces engine speed and beeps a warning if the engine overheats, has a low oil level or low oil pressure. For altitude compensation, the ECM system senses air density and modifies fuel and spark accordingly. And the self-diagnostic capabilities allow faster, more accurate maintenance on those rare occasions when the EFI system needs servicing.

Crusader chooses GM's MEFI-4 system because, like all of the components we use, it's state-of-the-art.
