Tank capacities — where the figures come from
-
Fuel varies by year
“225 gal (one steel tank plus two aluminum tanks)” — search excerpt (1968), seattle.boatshed.com · “Fuel Tank: 225 Gallons” — search excerpt (1985), mzyachts.com · “Fuel: 250 gallons in two painted steel tanks.” — broker listing (1992), preowned.grandbanks.com · “Fuel Tankage 250 gal” — spec database, oxfordyachtagency.comEarlier boats seem to have 225 gal (1968 and 1985 listings) and later ones 250 (a 1992 boat on Grand Banks' own pre-owned site; a Grand Banks dealer and Soundings also say 250). The changeover year isn't documented, so there's no single standard. An owners' forum describes one boat with four tanks of just under 50 gal each.
-
Water 110 gal
Oxford Yacht Agency, a long-time Grand Banks dealer, and a 1985 listing both say 110 gal; nothing from the builder.
-
Holding 30 gal
A 1985 listing says 30 gal; Oxford Yacht Agency's page says 20. Holding tanks were often added or replaced, and no builder figure was found.
-
Water heater AC + engine
“Hot water system 220V + engine Isotemp 40 liter” — broker listing, devalk.nlOnly one European broker listing gives a heater: a 40 L (10.6 US gal) Isotemp on 220 V and the engine, likely a replacement. The builder's 1990 sales literature gives 110 gal water and 250 gal fuel but no systems.
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
“This 1977 32-foot Grand Banks ... Includes Bow Thruster, Autopilot.” — search excerpt (1977), powerboatlistings.com · “an exceptional 1988 Grand Banks 32 Sedan ... low hour 210hp Cummins diesel, bow thruster” — search excerpt (1988), facebook.com · “a 1983 model Grand Banks 32 Sedan ... equipped with reliable Ford Lehman 120hp, bow thruster” — search excerpt (1983), youtube.com · “I am looking at an older glass Grand Banks ... considering having a bow thruster installed.” — search excerpt, trawlerforum.comThree separate Grand Banks 32s (1977, 1983, 1988) carry bow thrusters, and owners discuss adding them; the builder's 1990 catalogue page lists no thruster, and no builder option list was found. The listings don't say whether any was fitted at the factory.
-
Steering unknown
Only one owner report was found: a forum post describing a helm-shaft chain attached to two cables running to the rudder quadrant (chain-and-wire mechanical steering) on an older Grand Banks 32, which isn't enough to go on. The builder's 1990 catalogue page is silent.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on first year, last year — left blank rather than guessed.
Wood (mahogany) construction until 1973; fiberglass after. Production spanned roughly the mid-1960s to the mid-1990s (see disputed years). Fuel is 225 or 250 gal depending on year (the boat Soundings profiled had two 125-gal tanks). Lots of exterior brightwork; single engine sits on centerline with good access; long keel protects the prop. Cruise about 6-8 knots at roughly 2-3 gph.
Engines fitted

Ford Lehman 120 (2715E) — 120 hp, diesel, single
standard
The usual factory engine; broker listings for 1977 and 1983 boats show the original single Lehman 120.Sources: hmy.com · curtisstokes.net · curtisstokes.net · fairkeel.com
-
Ford Lehman 135 — 135 hp, diesel, single
standard
HMY/BoatUS lists a single 120 or 135 hp Lehman; an owner in the forum thread reports an original Lehman 135.Sources: hmy.com · trawlerforum.com
-
Cummins 6BT (210 hp) — 210 hp, diesel, single
common repower
Owners discuss replacing the Lehman with a Cummins 6BT/210; one poster says late-production 32s were also offered with the Cummins 210 from the factory, but no second source confirms that.Sources: trawlerforum.com · trawlerforum.com
Boats of the same model can differ — check which engines yours actually has before ordering parts.

Known problems for this model
-
Leaking original fuel tanks fuel
Owners and reviewers single out the two original under-side-deck fuel tanks as the model's weak point; many older boats need them replaced, which is costly and awkward. Check tank tops for rust and the deck-fill seal, which lets rainwater reach the tanks.soundingsonline.com · trawlerforum.com
-
Screwed teak decks leaking into core deck
The teak overlay is held down with hundreds of screws; failed bungs and seams let water into the deck core, which then rots and may require removing the teak and recoring.trawlerforum.com
-
Sliding window and lazarette hatch leaks deck
Sliding cabin windows commonly leak at the tracks, and lazarette hatches can leak and rot the plywood beneath them.trawlerforum.com
-
Aging original wiring electrical
Forum owners list the electrical system alongside tanks, decks and windows as the main things to budget for on a 40-plus-year-old Grand Banks.trawlerforum.com
Engines & parts
Ford Lehman 120 (6D380 / 2715E) parts: good
Factory standard engine — you entered “Ford Lehman 120 (2715E)”
Marinized by Lehman from the Ford of England 'Dorset' 2715E six-cylinder (380 cu in) industrial/truck diesel; Ford built the Dorset base engines 1964–1984. Base-engine internals interchange with the Ford 2715E, and marine-specific parts (raw water pumps, heat exchangers, injection elbows, gaskets, lift pumps, air filters) are widely stocked. American Diesel Corp (founded by former Lehman people) still sells parts, publishes spare-parts lists and gives technical advice. Rebuilt and used 120s are also sold by salvage yards.

Common problems (2)
-
Chronic oil leaks engine
Most 120s weep oil somewhere; owners often trace it to the rear of the engine near the heat exchanger (head/head gasket area) or to the drive seals of the gear-driven injection pump. Moderate oil use is treated as normal on these engines.trawlerforum.com · marineengine.com
-
Fuel leaks at injection pump, lift pump and return lines fuel
Slow diesel drips usually come from loose bleed screws or banjo washers, perished rubber injector return hoses, a failing lift-pump diaphragm, or worn internal seals in the Simms or CAV injection pump, which needs a pump shop to overhaul.yescenters.com

Cummins 6BT / 6BTA 5.9 parts: good
Factory common repower engine — you entered “Cummins 6BT (210 hp)”
Mechanically injected 5.9 L inline six from the Cummins B-series truck/industrial family, so base-engine parts are everywhere. Cummins still sells factory ReCon (remanufactured) marine 6BT/6BTA engines (152–210 hp ratings) with a 2-year/2000-hour warranty. Seaboard Marine is the best-known marine specialist, selling aftercooler/heat-exchanger service kits, upgraded raw water pumps and technical guidance; TAD also sells Cummins packages.
Parts sources: Seaboard Marine, Cummins (ReCon 6BT/6BTA), Diesel Pro Power
Common problems (2)
-
Aftercooler corrosion letting seawater into the intake cooling
On the turbo-aftercooled 6BTA the seawater-cooled aftercooler core has vertical tubes and an aluminum housing that corrodes from condensate; a leak can put salt water into the cylinders and wreck the engine. Owners pull, clean, grease and pressure-test the core every few years and fit new O-rings.trawlerforum.com · sbmar.com
-
Heat exchanger and aftercooler service cooling
Routine seawater-side service (O-rings, gaskets, zincs) is a recurring owner job; kits are sold for it and refilling coolant without trapping air is a common question.sbmar.com · sbmar.com
