Yamaha F9.9 / F9.9C / F13.5 / F15 / F15A / 9C Engine Service and Internal Parts Exploded Diagram

Complete engine service and internal parts overview shown in this diagram

This exploded view brings together oil filter, cylinder head, piston, main bearing, valve, carburettor, spark plug, thermostat, bearing and oil seal for Yamaha F9.9 / F9.9C / F13.5 / F15 / F15A / 9C. Start with the assembly area, then match the callout to the schedule rather than choosing a part from its appearance.

Identify the correct engine component

Separate routine service items from internal engine parts, then follow the numbered position into the matching schedule row. Production changes and engine variants can alter otherwise similar components.

Cylinder head and valve-train parts

Valves, camshaft parts, rocker components and related fasteners must be matched to the exact engine variant and numbered position. Similar-looking components can differ in dimensions, orientation or production revision.

Pistons, rods, crankshaft and bearings

Internal rotating parts require more than a visual match. Confirm the product reference and engine identity, then use the correct workshop procedure for measurements, clearances and installation.

Fuel, ignition and service references

Service parts can cover more than one engine family, but shared references must be supported at product level. Match the plug, filter, thermostat or fuel component to the exact reference and specification shown for the application.

Gaskets, seals and O-rings

Use the callout to distinguish individual sealing parts from complete gasket sets. Inspect the joint faces and replace related one-use seals only where the service procedure or scheduled kit requires them.

How to use the diagram and parts schedule

1. Confirm that the equipment is Yamaha F9.9 / F9.9C / F13.5 / F15 / F15A / 9C and check any page-level year or serial scope.
2. Find the required component on the exploded drawing and note its numbered callout.
3. Match the callout to the product code and OEM cross-reference in the parts schedule.
4. Apply every model, serial, ratio, side, material and configuration note shown for that row.
5. Compare the selected replacement with the removed part before installation.

Fitment and cross-reference checks

The page-level route is Yamaha F9.9 / F9.9C / F13.5 / F15 / F15A / 9C. It helps customers reach the correct drawing, but it does not make every product in the schedule interchangeable across every version of that model family.

An OEM number is an identification cross-reference. Confirm the exact product code, model designation and any bounded selection information before ordering. A product may also appear under another make or model only where that separate SKU-to-application fitment is independently supported.
