Sterndrive / Inboard Engine (Petrol/SI) · Shaft Line & Propulsion
This is a marine sterndrive/inboard engine. It is manufactured by Bombardier Recreational Products and designated as TBCXM1.639HB. This 4-stroke, 3-cylinder engine boasts a displacement of 1.6 liters and a supercharged design. The engine is electronically controlled and features multiport fuel injection. It produces 217 kW of power and has a maximum test speed of 8040 RPM. The TBCXM1.639HB is designed for a useful life of 480 hours or 10 years, whichever comes first. It is manufactured in the United States of America and operates on single fuel. Owners are advised to carry specific spare parts, including spark plugs, fuel filters, ignition system components, cooling pump parts, belts (where applicable), approved seals and gaskets, and sacrificial anodes. For sterndrives, additional spares like drive service seals, propeller hardware, and a spare propeller are recommended. For conventional inboards, stock transmission and shaft-interface service items should be available. During maintenance, it is important to inspect fuel and ignition components, cooling water flow, hoses, belts, and exhaust connections for signs of deterioration or leakage.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect fuel and ignition components, cooling-water flow, hoses, belts and exhaust connections for deterioration or leakage. Check the sterndrive or transmission lubricant for level, contamination and water ingress and inspect propeller and underwater gear for impact damage. Examine bellows, seals, anodes, steering, trim components and transom mounting where a sterndrive is fitted. Check engine mounts, alignment and coupling condition on inboard arrangements. Verify ventilation, fuel-vapor safety provisions, alarms, neutral-start protection and emergency shutdown functions appropriate to the petrol-engine installation. For cylinder dimensions, rotational speed, pressures, clearances, temperatures, wear limits and setting values, refer to the manufacturer documentation for the exact figure.
Carry specified spark plugs, fuel filters, ignition-system service parts, cooling-pump service components, belts where fitted, approved seals and gaskets, and sacrificial anodes. For sterndrives, useful spares include drive-service seals, propeller hardware and an appropriate spare propeller; for conventional inboards, stock transmission and shaft-interface service items according to the installation. Refer to manufacturer documentation for the exact spare selection.
