The Holset H2D Turbocharger (Cummins 6CTA 8.3 Marine 400C) — part number 3536271 is a genuine Holset part, supplied at £1,095 by G Service Power. It is brand new, held in UK stock and dispatched next day, worldwide.
Genuine Holset H2D turbocharger, assembly number 3536271, Cummins customer number 3536272, for the Cummins 6CTA 8.3 marine diesel at its 400 hp (400C) rating — the data plate reads Assy 3536271 / Serial W230918001 / Cust 3536272 / Model H2D, and the Holset Genuine Parts box label matches, packing date 18 September 2023 (see photos). The turbocharger uses exhaust energy to compress the intake air and force more of it through the aftercooler into the cylinders; it is the part replaced when boost falls away, the shaft develops play, or oil passes the seals into the intake or exhaust. The H2D has a 4-bolt divided (twin-entry) turbine inlet, 6-hole turbine outlet, clamp-type compressor outlet and an oil-cooled bearing housing, with the oil ports capped. Holset and distributor catalogues list 3536271 / 3536272 for the Cummins Marine 400C (6CTA 8.3, 400 bhp at 2600 rpm); other 6CTA ratings use different turbos — the 420C is listed with 3536273 — so match the number on your existing turbo's plate. Related service numbers: Holset service 3536272H, cartridge 3525301, repair kit 3545653. Condition: brand new, unused in its Holset box — fine handling marks on the plate and compressor outlet lip. Price £1,095. Gaskets and oil lines are not included. Please confirm against your engine serial number and CPL before ordering.
