Key Technical Specifications

Precision is critical when servicing supercharged powerplants. The documentation highlights engine timing data and exact valve clearance specifications. For the 1498 cc engine, intake valve clearances sit at 0.15–0.24 mm, while exhaust clearances are 0.32–0.41 mm. Fastener torque values are strictly defined for safe assembly, including the 36 Nm specification for engine mounting bolts.

Mechanics tackling the Digital Fuel Injection (DFI) will find essential baseline figures for system evaluation. This includes a throttle sensor output range of 1.08–1.18 V and an idling fuel pressure of 294 kPa.

Working on high-pressure fuel systems and supercharged engines carries inherent physical risks. Always consult a certified marine technician before initiating any heavy mechanical work, and strictly follow OEM safety protocols during the repair process to prevent equipment damage or personal injury.
