Volvo Penta D2-40

The D2-40 is the four-cylinder, 1.51-litre member of Volvo Penta’s D1/D2 sailboat range — essentially a D1-30 with one more cylinder (same 77 × 81 mm bore and stroke). It comes with an MS15 reverse gear or a 130S/130SR saildrive, has a 115 A alternator and freshwater cooling through a tubular heat exchanger. Versions A, B and F share the same service parts. Not to be confused with the larger D2-50 to D2-75, which share its oil and fuel filters but use a different impeller.

Wear parts & part numbers

Part	OEM number	Also fits	Note
Impeller kit (with gasket)	`22222936`^3,4,5replaces 3593659	Jabsco `18673-0001`^1,2	All versions; the same kit as the D1-30 and MD2010–2040 — but not the D2-50 to D2-75, which take another impeller. Beware of kit 21951346, often sold as the ‘D2-40 impeller’: per Volvo’s own list it does not fit.
Pump cover gasket	`840385`^3,6	—	Fit a new one whenever the cover comes off.
Raw water pump	`3593655`^3,7	—
Engine oil filter	`3840525`^5,8	—	Same filter on D1-30, MD2030/MD2040 and D2-55 to D2-75.
Fuel filter (engine)	`861477`^9,10,5	—	Engine-mounted spin-on fine filter.
Fuel pre-filter	`3581078` · `861014`^11,12	—	3581078 for the 877766/877767 water separator, 861014 (10 µm) for the 877762 housing — only if a Volvo Penta pre-filter is fitted; many boats have another make. Some dealer ‘service kits’ call 3581078 a fuel filter; it is the pre-filter element, not the engine-mounted filter.
Alternator V-belt	`3812145`^13,14,5	—	D2-40 belt; the D1-30 uses 21951188. Not sold online — dealer order.
Thermostat	`3842015`^15,16	—	Same as D1-30; the catalogue also lists a thermostat kit 3887340 for the D2-40 (contents not shown).
Air filter	`3809924`¹⁷	—	A complete, non-serviceable filter unit — the whole unit is replaced.
Service kit	`21189422`^18,5	—	Fits D2-40 and D1-30, all versions; the catalogue does not list the contents.
Onboard spares kit	`3884554`¹⁹	—	Dealer order only; contents not listed online.
Engine oil	`23909459`²⁰	—	VDS-4.5 SAE 15W-40, 1 l; the 5 l can is 23909460. Current Volvo documents also use it for the MS15 gear and the 130S saildrive.
Coolant	`22567295`²⁰	—	VCS yellow concentrate, 5 l; ready-mixed 5 l is 22567314. Only for engines already on VCS yellow.
Propeller shaft grease	`828250`²⁰	—	25 g tube.

Good to know

Lubricate a new impeller with glycerine only — other lubricants damage it — push it in with a clockwise twist and fit a new cover gasket. Volvo Penta says to always carry a spare impeller.²³
Check belt tension with the engine warm: the belt should give about 3–4 mm between the pulleys.²⁰
Volvo changed the oil for the MS15 gearbox and the 130S saildrive from ATF (2007 manuals) to SAE 15W-40 engine oil (2021 manual). Find out what is already in yours before topping up.²³
Never mix the older green Volvo coolant with the newer VCS yellow — check which one the engine has before topping up.²⁰
Saildrive and propeller anodes: zinc for salt water, magnesium for fresh water; replace at 50 % wear or at least once a season, never paint them.²¹
