Contact for Current AvailabilityConfirm specification before ordering. Specification published by Honda Marine against the BF90 family designation. This record is the BF90DK4 market variant, which Honda does not specify separately — the suffix denotes market and model year, not a different engine. Figures taken from the BF90 record, not from a sheet published for this code. We will confirm the specification in writing before quoting.

Configurations
2 catalogued builds. Shaft length, rotation, start type and control type all change which parts fit.
International specification
2 builds| Model code | Shaft | Rotation | Start | Control | Weight | Availability |
|---|---|---|---|---|---|---|
| BF90DK4-LRTN | Not specified | Standard | Not specified | Not specified | — | Contact for Current Availability |

Shaft length is not published for every configuration in this range. Where it reads “not specified”, the manufacturer code in the Model code column carries it — send us the code and we will confirm the shaft length before quoting rather than guess it.
These are international specification units. They are not supplied as United States-specification engines, and United States emissions eligibility must be confirmed separately before import or sale.
Market specification & emissions
- Emissions classification
- Not recorded
- EPA engine family
- Not recorded
- California (CARB)
- Not evaluated — confirm before order
- Warranty territory
- Confirmed at quotation
We do not infer emissions eligibility from a model designation. Where a value reads “not recorded” or “not evaluated”, we hold no documented evidence for that configuration and will confirm it before quoting. An international-specification engine is not a United States-specification engine, and a United States-specification engine is not automatically California eligible.
