Tank capacities — where the figures come from

Fuel 400 gal
“Fuel Tank: 1 x 400|gallon” — broker listing (2000), denisonyachtsales.com · “Fuel Capacity 440 US Gallons” — broker listing (2007), mvmischief.com

A 2000 boat agrees with 400; an owner's 2007 boat, built after the 1994–2002 years listed here, has 440, so later boats may have had more fuel.
Water 240 gal
“Fresh Water: 1 x 240|gallon” — broker listing (2000), denisonyachtsales.com · “Water Capacity 220 US Gallons” — broker listing (2007), mvmischief.com

The 2000 boat agrees; the owner's 2007 boat lists 220.
Holding 40 gal
“Holding: 1 x 40|gallon” — broker listing (2000), denisonyachtsales.com

One listing agrees.
Water heater AC + engine
“Kuuma 11 Gal Hot Water Heater 110 VAC/Engine (2021)” — broker listing (1998), curtisstokes.net

One 1998 boat for sale has a 2021 replacement 11 gal heater (110 V plus engine), so the original size isn't known. PassageMaker's owner story mentions a hot and cold cockpit shower as an extra but not the heater.

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
“Bow and Stern Thrusters” — broker listing (1995), everett.boatshed.com

One 1995 boat has bow and stern thrusters, origin unstated; no builder list or review was found.
Stern thruster unknown
“Stern Thruster” — broker listing (1995), everett.boatshed.com

Seen on one boat only, origin unstated.
Steering unknown
No builder, review or association source states the steering system.

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

Sources disagree on hull/keel type — left blank rather than guessed.

Workboat-styled pilothouse trawler with one or two staterooms; solid fiberglass hull with a deep keel. Upper helm concealed in the false stack; spacious engine room. Single 135 hp Sabre cruises 8 knots; 225 hp Perkins gives up to 11 knots.

Engines fitted

Cummins 6BTA 5.9 — 220 hp, diesel, single standard
Most common engine in listings and owner posts: two 2000 boats list a single Cummins 6BT/6BTA 5.9 (one rated 220 hp) and an owner reports a single 220 hp Cummins. HMY quotes 8 kn cruise with a single Cummins but says there were several engine options, so 'standard' here rests on owners and listings.

Cummins QSB 5.9-230 HO — 230 hp, diesel, single standard
An owner site for a 2007 Eagle 40 (built after the 1994-2002 span in this catalog entry) lists the electronic QSB 5.9 at 230 hp.

Sources: mvmischief.com
Perkins Sabre 135 — 135 hp, diesel, single factory option
HMY: a single 135 hp Sabre cruises about 8 kn. Sabre was the Perkins marine line.

Sources: hmy.com
Perkins 225 hp diesel (model not named by source) — 225 hp, diesel, single factory option
HMY: a 225 hp Perkins gives speeds up to about 11 kn.

Sources: hmy.com
Sabre 135 hp — 135 hp, diesel factory option
Cummins single — diesel factory option

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

Generator

“Northern Lights 6 kW Generator (2010), ~1060 hrs” — broker listing (1998), curtisstokes.net

One 1998 listing has a Northern Lights 6 kW fitted in 2010 (a replacement or later addition).

Engines & parts

Cummins 6BT / 6BTA 5.9 parts: good

Factory standard engine — you entered “Cummins 6BTA 5.9”

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.

Cummins QSB 5.9 parts: good

Factory standard engine — you entered “Cummins QSB 5.9-230 HO”

Electronically controlled (common-rail) successor to the mechanical 6BTA; current Cummins dealer network plus marine specialists such as Seaboard Marine supply parts. Electronic diagnostics require dealer tools more often than on the 6BTA.

Parts sources: Seaboard Marine, Diesel Pro Power

Common problems (3)

Raw water pump leaks cooling
Owners most often report the seawater pump leaking or being replaced around 1000 hours; an improved pump version is available. Some also updated fuel coolers as a precaution.
forums.ybw.com
Aftercooler service and cracking cooling
As with the 6BTA, the aftercooler needs periodic removal and resealing; a cracked aftercooler is generally replaced rather than repaired.

Burnt intake valves / loss of power engine
Seaboard Marine forum threads describe burnt valves and high-rpm power loss on some QSB 5.9s.
