Yanmar 4BY3-150 · 4BY3 family — specifications, its industrial/tractor base engine, cross-referenced parts and where to buy them.
The Yanmar 4BY3-150 is likely a marinized BMW B47D20 2.0 L common-rail diesel (N47 successor; same 84×90 mm / 1995 cc, 2014 launch match). Some internals may cross to BMW B47 — verify before ordering. Marinized externals are Yanmar-only. No BMW donor BOM loaded yet. source
