Hmm, while the manual is labeled 2001, it's made for the Indmar 5.7L small-block Chevy-based marine engines, which stayed mechanically pretty similar for several years.
Your 2006 5.7L Indmar Monsoon 340 is fuel-injected and still based on the same GM long block, so this manual should cover core engine procedures like:
-
Torque specs
-
Valve adjustments
-
Cooling system
-
Timing
-
General service
That said, it may not include details specific to your EFI system or Malibu-specific rigging, like ECM diagnostics or wiring unique to the 2006 model year. But for anything engine mechanical, it’s absolutely still relevant and useful.
