Gearcase and Water Pump Parts shown in this diagram
The source is headed Honda BF75AT / BF90AT and covers oil seals, O-rings, water-pump kit, impeller, key, pump plates and gaskets. The heading defines the route to this figure; it does not make every scheduled component interchangeable across every version.
Gearcase and water-pump checks
Use the numbered position and exact reference. Confirm the model, shaft and every seal, bearing, pump or hardware alternative printed for the selected row.
How to use this Honda diagram and schedule
- Record the complete Honda model designation and serial details.
- Locate the component and note its numbered callout.
- Match that callout to the RECMAR and OEM references in the schedule.
- Apply every model, serial, shaft and configuration note on the row.
- Compare the selected replacement with the removed part before installation.
Application and reference limits
The repeated source drawing is headed BF75AT and BF90AT. Use the exact callout and OEM cross-reference for every seal, bearing, pump component and propeller fastener; the lubricant references on the adjacent source page are supporting service information, not diagram callouts.
An OEM number is an identification cross-reference, not proof that every row fits every outboard named in the page heading. The exact row, model and reference control selection.
