MerCruiser Alpha One 5.7L (V8) 260 HP Inboard Gasoline Engine
MerCruiser Alpha One 5.7L is one of the most popular and reliable marine engines in history. Based on the legendary General Motors (GM) Small Block V8 architecture, this engine is renowned for its durability, ease of maintenance, and excellent torque characteristics.
The 260 HP rating typically refers to the carbureted or Throttle Body Injection (TBI) models produced roughly between the mid-1980s and the late 1990s/early 2000s (specifically models like the 5.7L Alpha and the later 5.7L EFI which often bumped to 300HP, but the 260HP remains the standard baseline for the carbureted version).
