Crusader Marine Engines
5.7L TBI, 5.7L MPI, 7.4L MPI
Crusader's new Electronic Fuel Injection (EFI), with sophisticated
microprocessor technology, provides optimum fuel flow for every imaginable condition. The
result: smooth idling and acceleration, responsive performance in all weather conditions,
reduced maintenance and instant starting (no manipulation of the throttle and no
stalling!).
And Crusader's unique EFI Computerized Engine Management System
continually monitors your engine operation...optimizing the fuel/air mixture and spark
advance, minimizing engine knock and engine damage from over-reving, adapting to changes
in altitude and providing self- diagnostic information for optimum engine operation,
performance and servicing.
Other XL innovations in the new electronic fuel injection models include
easy-to-service belt adjusters, Crusader's unique center manifold design that provides the
most efficient exhaust flow in the industry, and much more.
Models 5.7L TBI, 5.7L MPI and 7.4L MPI electronic fuel injection
inboards. Simply the most advanced EFI in the industry...only from the most experienced
manufacturer of gas inboard power in the world.
