Tank capacities — where the figures come from

Fuel varies by year
“Fuel tank capacity: 1000 USG (3846L)” — builder (Selene 45), seleneoceanyachts.com · “FUEL: 1,000 USG (3846L) ... [the 45] allows for 200 more gallons (757 l) of fuel [than the Selene 43]” — brochure (Selene 45), seleneoceanyachts.com · “FUEL: 840 gallons | 3180 liters” — broker listing (Selene 43 (typical)), selene43.com · “Fuel Tank: 950 Gallons” — search excerpt (2001 (43)), yachtr.com

Selene's own brochure and model page for the 45 give 1,000 US gal and say it carries 200 gal more than the original Selene 43, so the 43 had roughly 800 (43 listings give 800–950). This page covers both, so there's no single figure; 1,000 is right for the 45, whose length matches the one shown here.
Water 210 gal
“Fresh water tank capacity: 210 USG (807L)” — builder (Selene 45), seleneoceanyachts.com · “WATER: 210 USG (807L)” — brochure (Selene 45), seleneoceanyachts.com · “FRESH WATER: 300 gallons | 1135 liters (Two stainless steel tanks)” — broker listing (Selene 43 (typical)), selene43.com · “Fresh Water: 220 Gallons” — search excerpt (2001 (43)), yachtr.com

The builder's figure for the 45 is 210 US gal; our earlier 230 came from the HMY powerboat guide. Selene 43 listings range from 220 to 300, so the 43 may differ.
Holding unknown
“HOLDING BLACK: 40 gallons | 151 liters (One fiberglass tank)” — broker listing (Selene 43 (typical)), selene43.com · “Holding Tank: 40 Gallons” — search excerpt (2001 (43)), yachtr.com

The builder's page for the 45 gives no holding figure. Our earlier 60 came from the HMY powerboat guide; two Selene 43 listings say 40.

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
“raised pilothouse trawler with bow and stern thrusters” — search excerpt (2000), denisonyachtsales.com · “2 - 31's AGM batteries for the Bow Thruster” — broker listing (2001), mzyachts.com · “Side Power 15 HP proportional electric bow and stern thruster” — broker listing, selene43.com

Three separate listings (2000, 2001 and one undated) show bow thrusters, but no builder document says whether they were standard, optional or added. One listing names a 15 hp Side-Power, on a single boat.
Stern thruster unknown
“raised pilothouse trawler with bow and stern thrusters” — search excerpt (2000), denisonyachtsales.com · “2- 31's AGM batteries for the Stern Thruster” — broker listing (2001), mzyachts.com · “Side Power 15 HP proportional electric bow and stern thruster” — broker listing, selene43.com

The same three listings show stern thrusters too; no builder document says whether they were standard, optional or added later.
Steering unknown
Builder model pages and the S45 Explorer e-brochure do not describe steering.

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

Sources disagree on first year, engines, hp (standard Cummins per HMY), holding tank — left blank rather than guessed.

Sold as the Solo 43 in 1998-2000, Selene 43 afterwards and Selene 45 from 2010. Ballasted (about 3,000 lb) displacement hull with Portuguese bridge; center galley; big commissary storage between engine room and lazarette. Single Cummins cruises 8 knots with 2,000+ nm range.

Engines fitted

Cummins 6BTA5.9-M (180 hp rating) — 180 hp, diesel, single standard
Early Solo 43 / Selene 43 (1999-2000 build); two separate 2000 hulls list a single 180 hp 6BTA5.9-M, no repower mentioned.

Sources: curtisstokes.net · curtisstokes.net
Cummins 220 hp (model not stated) — 220 hp, diesel, single standard
HMY's main text: single 220 hp Cummins, 8 kn cruise, 2,000+ mile range. HMY's BoatUS note says 210 hp (see disputed).

Sources: hmy.com
Cummins QSB 5.9 (230 hp rating) — 230 hp, diesel, single standard
Dealer page for the later Selene 45 (deep-hull version) calls the 230 hp QSB 5.9 the standard engine, carried over from the 43.

Cummins 6BTA5.9 (280 hp rating) — 280 hp, diesel, single factory option

A 2006 hull is listed with a single common-rail QSB 5.9 at 305 hp.

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

Generator

“GENERATOR: 9KVA in soundshield” — brochure (2017), seleneoceanyachts.com · “GENERATOR: Onan 12.5 KW generator with Sound Shield” — broker listing, selene43.com · “Upgraded, Northern Lights Generator (12KW)” — search excerpt (2006), denisonyachtsales.com

The builder's S45 Explorer e-brochure lists a 9 kVA generator in a sound shield without saying standard or optional; its 38 Voyager brochure lists one the same way and calls it optional in the text. Individual 43s show a 12.5 kW Onan (a dealer page for one boat) and a 12 kW Northern Lights (a 2006 listing and a Selene Owners Association sale post).

Engines & parts

Cummins 6BT / 6BTA 5.9 parts: good

Factory standard engine — you entered “Cummins 6BTA5.9-M (180 hp rating)”

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 optional engine — you entered “Cummins QSB 5.9 (305 hp rating)”

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
