Tank capacities — where the figures come from
-
Fuel 1,100 gal
“Fuel: 1,100 gal.” — review (1997-2012), powerandmotoryacht.com · “The fuel tank holds 1,100 gallons.” — search excerpt (2005), novesea.comA Power & Motoryacht used-boat review and listings agree; builder (Westport/Pacific Mariner) documents weren't found online.
-
Water 285 gal
“Water: 285 gal.” — review (1997-2012), powerandmotoryacht.com · “Fresh-water capacity is 285 gallons” — search excerpt (2005), novesea.comMagazine review and listings agree.
-
Holding unknown
“the holding tank holds 125 gallons” — search excerpt (2005), novesea.comThe HMY powerboat guide lists both 110 and 125 gal; a 2005 65 SE listing says 125. That leans toward 125, but no builder or magazine figure settles it.
-
Water heater engine
“30-gallon hot water heater with engine heat exchanger” — broker listing (2000), alexandermarineusa.comOne broker listing (2000 boat) gives a 30 gal heater with engine heat exchanger; no builder or review figure 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 unknown
Broker text for a 2000 Pacific Mariner 65, repeated by several brokerages and apparently copied from builder marketing, lists a hydraulic bow thruster among standard features, and a spec database's 2000 equipment list includes bow thruster control. No builder document or review confirms it as standard; worth confirming on your boat.
-
Steering hydraulic
“Hydraulic steering with power assist (2000 Pacific Mariner 65 Motoryacht features and equipment)” — spec database (2000), boatsdata.com · “Hydraulic Steering w/ Power Assist; 24" Stainless Steel Destroyer Wheel” — broker listing (2000), breweryacht.comPower-assisted hydraulic steering, according to one spec database, matching a 2000 boat's broker listing; no maker is named. The Power & Motoryacht used-boat review page gives only specifications.
Thrusters and steering are often replaced — check the units on your boat before ordering parts.
Sources disagree on first year, last year, displacement, engines[MTU].hp, holding tank — left blank rather than guessed.

Engines fitted
-
Caterpillar 3406E — 800 hp, diesel, twin
standard
HMY: 800 hp Cats give about 22 kn cruise, 26-27 top; Power & Motoryacht lists twin 800 hp 3406Es as a power option; 2000 and 2001 boats list twin 3406Es.
-
Detroit Diesel Series 60 (DDC/MTU) — 825 hp, diesel, twin
factory option
Alternative to the Cats, seen on later boats: a 2007 and a 2009 PM 65 list twin DDC/MTU Series 60s at 825 hp, matching HMY's 825 hp MTU figure. Power & Motoryacht gives 750 hp (see disputed).Sources: hmy.com · yachtingmagazine.com · bluewateryachtsales.com · powerandmotoryacht.com
Boats of the same model can differ — check which engines yours actually has before ordering parts.
Generator
Twin Northern Lights diesel generators (20 kW + 12 kW) recur on two separate listed boats, and another listing shows Northern Lights 16 kW + 20 kW. The Power & Motoryacht used-boat review gives no generator detail. The pattern looks factory-installed, but no builder list was found to confirm it.
-
Northern Lights — 20 kW, diesel
Paired with a 12 kW Northern Lights on the same boats; the 20 kW unit drives a power take-off for the hydraulic bow thruster. Seen on separate boats (2000 and 2003); a 2009-era listing shows 16 kW + 20 kW instead. Whether it was standard or optional isn't documented.“one 20kw Northern Lights generator ... P.T.O for hydraulic bow thruster; one 12kw Northern Lights generator” — broker listing (2000), alexandermarineusa.com · “Northern Lights 20 kW generator (5400 hours) with PTO for bow thruster; Northern Lights 12kW second generator” — broker listing (2003), americanyachts.com
-
Northern Lights — 12 kW, diesel
Second (smaller) generator on the same two boats.“one 12kw Northern Lights generator with 942 hours with sound shield” — broker listing (2000), alexandermarineusa.com · “Northern Lights 12kW second generator (1723 hours)” — broker listing (2003), americanyachts.com
Generators are often replaced or added — check the unit's own plate before ordering parts.
