Confirm specification before ordering. Specification published by Honda Marine against the BF40 family designation. This record is the BF40DK2 market variant, which Honda does not specify separately — the suffix denotes market and model year, not a different engine. Figures taken from the BF40 record, not from a sheet published for this code. We will confirm the specification in writing before quoting.

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.

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.
