Tank capacities — where the figures come from
-
Fuel 40 gal
“150 l” — builder, jeanneau.com · “The manual 150 [litres fuel]” — search excerpt, jeanneau.proboards.com · “The brochure states 100 litres for fuel” — search excerpt, jeanneau.proboards.comJeanneau's model page gives 150 L = 39.6 US gal. An owners' forum post says the owner's manual gives 150 but the brochure 100; the builder's site sides with the manual.
-
Water 92 gal
“350 l” — builder, jeanneau.com · “The manual ... 350” — search excerpt, jeanneau.proboards.com · “[brochure] 300 for water” — search excerpt, jeanneau.proboards.comThe builder's site gives 350 L = 92.5 US gal, matching the manual as quoted on the owners' forum; the brochure reportedly says 300 L.
-
Holding unknown
No holding figure on the builder page.
-
Water heater unknown
Jeanneau's model page lists only tank capacities; no review, owners'-forum or listing figure found.
Tanks are often replaced or added on older boats — check the tank labels or a survey for yours.
Thrusters and steering — where this comes from
-
Bow thruster unknown
No builder option list found.
-
Stern thruster not fitted
Our earlier figure of none has no source, and nothing was found either way.
-
Steering unknown
“The broad aft section allows pedestal steering and a cockpit table.” — builder, jeanneau.comJeanneau's model page confirms pedestal wheel steering but not whether the pedestal drives cable-and-quadrant or a geared steerer, so no type is shown.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on hp (standard Volvo) — left blank rather than guessed.
Also called the Jeanneau 36.2; similar boats sold as the Moorings 36.2 and Stardust 363.2 (charter fleets). No model-specific problem sources were read.
Engines fitted
-
Volvo Penta MD2040 (or smaller Volvo on base boats) — 40 hp, diesel, single
standard
Wikipedia says the boat was fitted with a Volvo Penta MD2040 (40 hp) or a Yanmar (27 hp). sailboatdata and Bolsa de Navegantes give the original equipment as a 27 hp Volvo diesel. The SVB owners' club lists the MD2040 among engines fitted to members' 36.2s.Sources: en.wikipedia.org · sailboatdata.com · bolsadenavegantes.net · svb24.com
- Volvo Penta — 27 hp, diesel standard
-
Yanmar 3GM30F — 27 hp, diesel, single
factory option
Wikipedia names a 27 hp Yanmar as the alternative to the Volvo; the SVB owners' club lists the Yanmar 3GM30F as fitted to members' 36.2s.Sources: en.wikipedia.org · svb24.com
-
Yanmar 2GM15 — diesel, single
factory option
Also listed by the SVB owners' club as fitted to a member's 36.2; rating not given there. Factory or later fit not stated.Sources: svb24.com
-
Volvo Penta D2-40 — 40 hp, diesel, single
common repower
The SVB owners' club lists the Volvo D2-40 among engines fitted to members' 36.2s (its member counts are per engine across all boats, so they do not show how common it is on this model). SVB does not say factory vs later; classing it as a repower is an inference because the D2 series is newer than the MD20xx engines the boat launched with.Sources: svb24.com
Boats of the same model can differ — check which engines yours actually has before ordering parts.

Engines & parts
Volvo Penta MD2010 / MD2020 / MD2030 / MD2040 parts: good
Factory standard engine — you entered “Volvo Penta MD2040 (or smaller Volvo on base boats)”
Shibaura-based small diesels (MD2030 is a 3-cylinder, 29 hp, built 1994–2006 per a Swedish rebuild shop). Parts are still sold through the Volvo Penta network and some cross-reference to related Shibaura engines; aftermarket stainless exhaust elbows (replacing Volvo 861906) are widely sold. Often paired with Volvo 120S/130S saildrives, whose rubber diaphragm seal Volvo says to replace at least every seven years.
Parts sources: AB Marine Service (exhaust elbow 861906), FYB Marine (saildrive diaphragm seal kit), Parts4Engines
Common problems (3)
-
Exhaust elbow corrosion and clogging exhaust
The cast exhaust elbow and pipe corrode or clog with seawater scale and carbon; stainless aftermarket elbows are a common fix.meksta.com · ab-marineservice.com
-
Saildrive diaphragm seal replacement running gear
Volvo's 7-year saildrive diaphragm replacement (sometimes an insurance requirement) is a frequent question; DIY is possible in a day with a haul-out, while yard quotes vary widely.forums.ybw.com · bavariayacht.org · fybmarine.shop
-
Blocked heat exchanger, broken impellers, glow plug faults cooling
Other frequent faults are internally blocked heat exchangers, disintegrating raw-water impellers, failed preheat/glow plugs and carboned injectors.meksta.com

Yanmar 3GM / 3GM30F parts: good
Factory optional engine — you entered “Yanmar 3GM30F”
Very popular (used 3GM30Fs sell for $3,000+) and supported by a strong parts network. Cylinder head overhauls (valve seals, lapping, injector service) are a common, parts-supported repair.
Parts sources: Mack Boring & Parts (Yanmar distributor), HDI Marine (stainless exhaust elbows), Parts4Engines
Common problems (2)
-
Overheating at cruise rpm cooling
The 3GM30F has a known overheating tendency linked to its heat exchanger; owners also trace it to coked elbows, worn impellers, scaled heat exchangers or air in the raw water circuit. Some heat exchangers were replaced under warranty.forums.sailboatowners.com
-
Mixing elbow corrosion exhaust
OEM elbows corrode internally and should be inspected or replaced with stainless versions before they let water into the engine.practical-sailor.com · facebook.com

Volvo Penta D1 / D2 series (D1-13 to D2-75) parts: good
Factory common repower engine — you entered “Volvo Penta D2-40”
Current-generation small Volvo diesels (Perkins-derived per owners). Glow plugs, injectors and filters can be bought cheaper via Perkins and aftermarket sources; stainless replacement exhaust elbows are sold aftermarket.
Parts sources: MarineDustrie, AB Marine Service (exhaust elbow)
Common problems (3)
-
Exhaust elbow / manifold corrosion exhaust
The cast elbow rots and has a narrow water passage, which lets water back into the manifold and corrode it through where the two meet; an aftermarket stainless elbow is the usual fix.sailnet.com · myhanse.com
-
Fuel pump controller failure fuel
Contamination or failure of the fuel pump controller is listed as one of the most common D1 faults.marinedustrie.com
-
Overheating from corroded heat exchanger/manifold cooling
Corrosion holes in the combined heat exchanger/manifold cause overheating on D1 and D2 engines.myhanse.com · facebook.com
