Tank capacities — where the figures come from
-
Fuel 66 gal
“Total fuel tank (s) capacity 250 Litre” — search excerpt (1989 (one listing)), jachtmakelaardijkappers.nlOne Dutch listing gives 250 L (66 US gal), matching our earlier figure; the builder brochure's spec box has no tank figures.
-
Water 79 gal
“Capacity 300 litre” — broker listing (one boat), hiswa.nl · “300 liters (79 US gallons, 65 imperial gallons) fresh water capacity” — search excerpt, yachtdatabase.comA listing and a spec database both give 300 L (79 US gal); no builder figure.
-
Holding unknown
“Inhoud 70 litre (waste water tank, stainless steel)” — broker listing (one boat), hiswa.nlOne listing only (70 L = 18 US gal); the tank may not be original.
-
Water heater AC
“30-litre calorifier - working on shore power when last used” — broker listing (1988), williamsandsmithells.comOne UK broker listing (a 1988 boat) has a 30 L (7.9 US gal) calorifier, or hot-water tank, not confirmed as original. The German Najad brochure (about 1985) gives the layout, dimensions and a Volvo Penta 2003T engine but no systems list.
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 often added later
“Bow thruster Lewmar 6hp - 2012 (Najad 360)” — broker listing (2012), berthonscandinavia.se · “Used NAJAD 360 for sale: Seaworthy centercockpit cruiser built in 1991 with furling mast and bow thruster.” — search excerpt (1991), diamond-yachts.deTwo separate boats for sale carry bow thrusters, one added in 2012 (a Lewmar 6 hp unit, on that boat only). The German builder brochure from about 1985 shows no thruster.
-
Stern thruster not fitted
Our earlier figure of none has no source, and nothing was found either way.
-
Steering unknown
The German builder brochure from about 1985 shows a centre-cockpit pedestal wheel in photos but has no steering text. One broker listing describes wheel steering with wire and stainless sprockets (chain-and-wire), but a listing alone doesn't settle the type or brand.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Fin with skeg-hung rudder; iron ballast. Replaced by the Najad 361 in 1994. No model-specific problem sources were read.
Engines fitted

Volvo Penta 2003T (turbo) — 43 hp, diesel, single
standard
Sailboatdata lists a Volvo Penta 2003 at 43 hp; listing snippets (a 1987 boat on Rightboat and a Danish boat on Scanboat) name it the 2003T at 43 hp. The listing pages themselves had been taken down.Sources: sailboatdata.com
-
Volvo Penta D2-40 (D2-40B) — 40 hp, diesel, single
common repower
A 1988 Najad 360 was repowered with a 40 hp D2-40B in 2009; other 360s for sale also list Volvo D2-40s.Sources: hiswa.nl
Boats of the same model can differ — check which engines yours actually has before ordering parts.

Engines & parts
Volvo Penta 2001 / 2002 / 2003 / 2003T parts: limited
Factory standard engine — you entered “Volvo Penta 2003T (turbo)”
Parts are available through Volvo Penta but owners consider them unique and overpriced (e.g., 2003T turbo, aluminum heat exchanger and oil cooler each quoted in the $1,700–3,000 range). Workarounds include converting the 2003T cooling system to aftermarket cupronickel heat exchanger and oil cooler, using the common aftermarket turbo, and cross-referencing some Perkins parts. Parts4Engines stocks aftermarket service parts.

Common problems (3)
-
Aluminum oil cooler and heat exchanger failures (2003T) cooling
The aluminum oil cooler and heat exchanger are the usual first failures, and genuine replacements are very expensive, so some owners convert to aftermarket coolers or repower.cruisersforum.com · facebook.com
-
Carboned exhaust elbow and turbo from low-load running exhaust
Long periods at low rpm carbon up the elbow and the 2003T turbo; the turbo can also be wrecked if it ingests the intake silencer foam.cruisersforum.com
-
Hard starting on older raw-water-cooled 2002s engine
Original raw-water-cooled 2002s are described as reliable but difficult to start.forums.ybw.com

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
