Tank capacities — where the figures come from
  • Fuel 359 gal
    “Fuel Capacity 359 Gals. 1,359 ltr” — brochure (buyers guide effective Aug 1, 1991), hatterasowners.com · “FUEL: 359 gal” — review, powerandmotoryacht.com
    The builder's buyers' guide (effective 1 Aug 1991, from the Hatteras owners' archive) gives 359 gal; Power & Motoryacht magazine agrees.
  • Water 110 gal
    “Freshwater Capacity 110 Gals. 416 ltr” — brochure (buyers guide effective Aug 1, 1991), hatterasowners.com · “WATER: 110 gal” — review, powerandmotoryacht.com
    The builder's 1991 buyers' guide gives 110 gal (plus an 11-gal water heater listed separately); Power & Motoryacht magazine agrees.
  • Holding 60 gal
    The builder's 1991 buyers' guide lists a sewage holding tank but no capacity; no other source was found.
  • Water heater 11 gal · AC · standard
    “Pressurized freshwater system with 11-gallon electric water heater (Standard Equipment)” — builder (1991-92 (effective Aug 1, 1991)), hatterasowners.com · “Pressurized freshwater system with electric water heater (Standard Equipment)” — builder (1989), hatterasowners.com · “Freshwater pressure system with electric water heater and water fill hose for engines and generator (Standard Equipment)” — builder (1986), hatterasowners.com
    Hatteras buyers' guides list an electric water heater as standard in 1986, 1989 and 1991; only the 1991 guide gives the size (11 gal). No engine heat exchanger mentioned. Fresh water 110 gal.

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 not fitted
    “40 Double Cabin buyers' guide effective August 1, 1986: standard equipment and optional equipment lists, no thruster” — builder (1986), hatterasowners.com · “40 Double Cabin buyers' guide, prices Aug 1, 1991 - Jul 31, 1992: standard equipment and optional equipment lists, no th” — builder (1991-1992), hatterasowners.com
    Neither the 1986 (Series I) nor the 1991 (Series II) builder buyers' guide offers a thruster, standard or optional.
  • Stern thruster not fitted
    “40 Double Cabin buyers' guide effective August 1, 1986: standard equipment and optional equipment lists, no thruster” — builder (1986), hatterasowners.com · “40 Double Cabin buyers' guide, prices Aug 1, 1991 - Jul 31, 1992: standard equipment and optional equipment lists, no th” — builder (1991-1992), hatterasowners.com
  • Steering hydraulic
    “Flying Bridge: ... Dual lever clutch and throttle controls; Hydraulic steering (standard equipment)” — builder (1986), hatterasowners.com · “Flying Bridge: ... Dual lever clutch and throttle controls; Hydraulic steering (standard equipment)” — builder (1991-1992), hatterasowners.com
    Hydraulic steering standard in both builder buyers' guides; maker not named. Salon (lower) helm controls were an option.

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

Sources disagree on number built, hp (Caterpillar diesel option) — left blank rather than guessed.

Last of the 'small' Hatteras motor yachts; cored hullsides and prop pockets. Interior and flybridge redesigned in 1990. Heavy for size: gas engines cruise only 13-14 kt. Well over 100 built (see disputed). Draft 4.75 ft per HMY.

Engines fitted

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

Generator

standard

“8Kw diesel generator with seawater strainers, freshwater cooling, remote start, hour meter, and water lift muffler and s” — builder (1991-92), hatterasowners.com · “9Kw gas or 8Kw diesel generator (Standard Equipment)” — builder (1989), hatterasowners.com · “6.5KW gas or 8KW diesel generator with sea water strainers, freshwater cooling, remote start ... (Standard Equipment)” — builder (1986), hatterasowners.com

Generator standard in all three Hatteras buyers' guides; size follows the main-engine fuel. Hatteras does not name the generator make.

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

Engines & parts

Crusader 350 / 454 inboard gas V8 parts: good

Factory standard engine — you entered “Crusader 454 (7.4L gas V8)”

GM-based inboard engines; Crusader (now part of Pleasurecraft Marine Engine Co.) still publishes illustrated parts manuals and sells through distributors. Go2marine stocks Crusader manifolds, risers, raw water pumps and ignition parts; Osco and Barr make aftermarket manifolds, and new GM/Crusader base engines are sold by rebuilders.

Parts sources: Crusader Engines, Go2marine (Crusader parts), 1-800-RUNS-NEW (GM & Crusader base engines)

Common problems (1)
  • Clogged or failing manifolds/risers exhaust
    Owners find individual risers running much hotter than the others (a sign of internal blockage) and debate replacing vs. flushing; Osco manifolds are often preferred as closest to OEM.

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

Factory optional engine — you entered “Caterpillar 3208TA”

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.

Sources disagree on horsepower — left blank rather than guessed.

Detroit Diesel 6-71 (inline, N / T / TI) parts: good

Factory optional engine — you entered “Detroit Diesel 6-71”

Two-stroke 71-series engine with a huge commercial, bus and marine population; basic engine parts and complete overhaul kits (liners, pistons, injectors, blowers, bearings, gaskets) are cheap and widely available from Diesel Pro Power, Highway and Heavy Parts and others. Some marine-specific parts (coolers, manifolds) are harder to find. Designed to be rebuilt in-frame repeatedly; naturally aspirated engines with good care have been reported past 15,000 hours, turbo versions more like 3,000–5,000.

Parts sources: Diesel Pro Power (Detroit Diesel parts), Highway and Heavy Parts (Series 71)

Common problems (2)
  • Oil leaks engine
    Owners describe 71-series Detroits as habitual oil leakers; chasing leaks with the right gaskets and sealants is a routine topic even on freshly rebuilt engines.
    trawlerforum.com · cruisersforum.com
  • Noise and smoke exhaust
    Injector and exhaust noise is loud unless mufflers are well designed, and some smoke is typical of the two-stroke design.
