Tank capacities — where the figures come from

Fuel 600 gal
No builder document could be checked, but every source agrees on 600 gal: the Grand Banks dealer Oxford Yacht Agency, a Mad Mariner review reproduced by the broker Denison, Denison's powerboat guide, and a 1992 boat listed with two 300 gal aluminium tanks.
Water varies by year
“Water Capacity 235 - 300 Gallons” — review, denisonyachtsales.com · “Water 295 Gals” — spec database, oxfordyachtagency.com · “Water ...265 gals.” — search excerpt, cdn.denisonyachtsales.com · “the normal 250 gallons of fresh water tankage” — review, passagemaker.com · “(2) 130-gallon painted aluminum water tanks (NEW, 2024)” — search excerpt (1992), northstaryachtsales.com

Water tankage changed over the 1975–2004 run; a review gives a 235–300 gal range, and the hull was lengthened and widened in 1991. Sources give 250, 260 (a 1992 boat, with same-size replacement tanks), 265 and 295, but none ties a figure to years, so there's no single standard.
Holding 50 gal
Denison's powerboat guide says 50 gal of waste tankage, and a 1992 boat has a 50 gal holding tank. Nothing from the builder.
Water heater AC + engine
“12 gallon hot water heater (110V and plumbed to engine)” — broker listing (1981), edwardsyachtsales.com · “12 gallon hot water heater” — broker listing (1980), boats-from-usa.com · “onan 8kw generator, 20 gallon hot water heater” — search excerpt (1986), youtube.com

Only broker listings give a size, and they differ: 12 gal on a 1980 and a 1981 boat, 20 gal on a 1986 boat, possibly a change over the 1975-2005 run or replacements. An operation manual giving another size exists only as an unofficial copy, so it isn't relied on here, and no builder figure was 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 often added later
“Recent Bow Thruster ... 1983 Grand Banks 42 Classic” — search excerpt (1983), yachtworld.com · “1986 Grand Banks 42 Classic Trawler Well maintained and loved Classic with bow thruster” — search excerpt (1986), powerboatlistings.com · “a SidePower Bow Thruster makes docking effortless” — search excerpt (1989), rubiconyachts.com

Three separate 1980s boats for sale carry bow thrusters, one described as recent, and no builder document was found listing a thruster as standard or option. One listing names Side-Power, but on a single boat, so no unit is shown here.
Steering mechanical
“Surprisingly, for having wire cable steering, steering was remarkably easy.” — review, yachtsurvey.com · “Does anyone have any pics of the GB 42 cable steering? ... She's a 1966 42 classic.” — search excerpt (1966), trawlerforum.com

A surveyor's boat test describes wire-cable steering (chain and wire to a quadrant), which fits our earlier figure of mechanical. Our earlier claim that hydraulic steering became an option around 1995 wasn't found in any source.

Thrusters and steering are often replaced — check the units on your boat before ordering parts.

Sources disagree on displacement — left blank rather than guessed.

Wood until 1973 (fiberglass from hull 353); the Classic name/fiberglass model is dated 1975-2005 by the builder. Hull lengthened and widened about 1991-92 from hull #1203 (to 43.25 ft LOA, 14.08 ft beam). A single engine was standard but most buyers chose twins. The 1,555 hulls figure (Oxford Yacht Agency) covers all 42 variants, including wood boats, Europa and Motor Yacht, so hulls_built for the Classic alone is left blank. Single-engine boats benefit from a thruster because the long keel turns poorly.

Engines fitted

Ford Lehman 120 — 120 hp, diesel, twin standard
Power on the early fiberglass 42s; an owner-profile of a 1980 hull describes its twin 120s as the economy choice.

Sources: denisonyachtsales.com · passagemaker.com · trawlerforum.com
Ford Lehman 135 (later Sabre Lehman 135) — 135 hp, diesel, twin standard
Twin 135s were the usual standard power on older 42s; later boats got the Sabre-built version of the 135.

Sources: denisonyachtsales.com · trawlerforum.com
Caterpillar 3208 NA — 210 hp, diesel, twin factory option
Naturally aspirated 3208s; common toward the later (c.1990s) end of the run. A 1990s factory demonstrator was built with them.

Sources: hmy.com · passagemaker.com · trawlerforum.com
Cummins 210 hp — 210 hp, diesel, twin factory option
HMY lists 210 hp Cummins as the alternative to 210 hp Cats; model not named.

Sources: hmy.com
Cummins 300 hp (6-cyl) — 300 hp, diesel, twin factory option
Denison review cites a pair of 300 hp Cummins among later power choices; an owner reports 315 hp inline-six Cummins.

Sources: denisonyachtsales.com · trawlerforum.com
Caterpillar 3208 TA — 375 hp, diesel, twin factory option
Top-end option; guides give a 14-15 knot cruise.

Sources: hmy.com · denisonyachtsales.com
Ford Lehman SP225 (Sabre Lehman) — 225 hp, diesel, twin factory option
Reported by one owner only; not confirmed in a builder or guide source.

Boats of the same model can differ — check which engines yours actually has before ordering parts.

Generator

Generators appear on nearly every listing seen, in several makes: Onan 8 kW (review boat; 1986), Westerbeke 8 kW (1980), Northern Lights 7.5 kW (1998 unit on a 1981 boat), Onan 6.5 kW (French listing). No builder document says whether the factory fitted one as standard or option.

Onan — 8 kW
Named in a surveyor's boat review (reviewed boat) and in a 1986 boat's listing; fuel not stated.

“The one tight spot is the Onan 8kw generator that is located between the fuel tanks” — review, yachtsurvey.com · “onan 8kw generator, 20 gallon hot water heater” — search excerpt (1986), youtube.com

Generators are often replaced or added — check the unit's own plate before ordering parts.

Known problems for this model

Screw-fastened teak over plywood-cored deck deck
The deck is fiberglass over plywood with a screwed teak overlay; as bedding and fasteners loosen, water rots the core. Major deck repair can run well into five figures if neglected.
denisonyachtsales.com
Corroding steel fuel tanks fuel
The two steel tanks outboard of the engines can corrode badly; replacement is expensive, so keep them dry and isolated from wood supports.
denisonyachtsales.com
Osmotic blistering hull
Older hulls without a barrier coat often show blisters, worse in warm water; a surveyor reports them as rarely structural but costly to repair and a hit to resale.
denisonyachtsales.com
Sliding window leaks deck
Sliding cabin windows leak unless tracks and drains are cleaned and maintained each year.
denisonyachtsales.com
Moisture-damaged engine room insulation other
Until about 1991 the engine room was lined with commercial acoustic tiles that do not tolerate moisture well and are often degraded.

Engines & parts

Ford Lehman 120 (6D380 / 2715E) parts: good

Factory standard engine — you entered “Ford Lehman 120”

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.

Parts sources: American Diesel Corp, Go2marine (Ford Lehman parts collection), Fred Warner Marine & Outdoors

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.

Caterpillar 3208 (NA / T / TA) parts: good

Factory optional engine — you entered “Caterpillar 3208 NA”

V8 introduced in the 1970s and discontinued in the late 1990s (Big Bear Engine gives 1999). Naturally aspirated versions run about 210 hp; turbo and turbo-aftercooled versions go up to 435 hp. Cat dealers still supply many genuine parts by serial number, and aftermarket in-frame/overhaul kits (pistons, rings, liners, bearings) are sold by Diesel Pro Power, Highway and Heavy Parts and others; complete remanufactured long blocks are also sold. The block is unsleeved from the factory but can be bored and sleeved during a rebuild.

Parts sources: Diesel Pro Power, Highway and Heavy Parts (Cat 3208), Big Bear Engine Company (3208 long blocks)

Common problems (3)

Aftercooler failure flooding the engine (TA models) cooling
The seawater-cooled aftercooler on turbo-aftercooled 3208s has aluminum parts that corrode; a failure can let seawater into the cylinders. Owners pull, clean, grease and pressure-test aftercoolers every 2–3 years and some replace them on a fixed schedule.
trawlerforum.com · forums.ybw.com
Short life at high ratings / overloading engine
The higher-rated 3208TA engines last longer when run well below full power and propped so they can reach rated rpm; overheating or running at full load continuously shortens life.
trawlerforum.com · trawlerforum.com
Overheating at high throttle cooling
Common causes owners check are clogged heat exchangers, thermostats, fouled keel coolers or restricted raw water flow, and faulty temperature senders.
