Tank capacities — where the figures come from
  • Fuel 18 gal
    “18 gallon (68 ltr.) aluminum fuel tank” — brochure (2004), janice142.com
    Pacific Seacraft's own specification sheet dated March 15, 2004 (posted on an owner's website).
  • Water 40 gal
    “40 gal.(151 ltr.) GRP water tank” — brochure (2004), janice142.com
    From the builder's 2004 spec sheet. SailWiki notes an optional extra 30 gal of water on some boats, not confirmed by a builder source.
  • Holding 15 gal
    “Marine head with 15 gal. holding tank” — brochure (2004), janice142.com
    From the builder's 2004 spec sheet; the figure for earlier (1984-99) boats wasn't confirmed.
  • Water heater AC · factory option
    “Hot & cold fresh water system. Galley & head sink faucets fitted with temperature mixing valves ... (req. shore power sy” — builder (2004), janice142.com
    The builder's 2004 specification sheet and option price list show hand-pump fresh water only on the base boat; a hot and cold water system was an option that needed the optional 110 V shore-power system. Heater capacity isn't stated, and no engine heat exchanger is mentioned.

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
    “Specification sheet (base price March 15, 2004) with features list and full optional-equipment price list - no thruster” — builder (2004), janice142.com
    The builder's 2004 Dana 24 specification sheet lists standard features and every priced option; no thruster appears. Earlier years not checked against a builder list.
  • Stern thruster not fitted
    “Specification sheet (2004) with full optional-equipment price list - no thruster offered” — builder (2004), janice142.com
  • Steering tiller
    “Chrome tiller head and laminated wood tiller.” — builder (2004), janice142.com
    Tiller standard on the transom-hung rudder; the 2004 option list offers no wheel steering.

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

Hull length (LOD) 24.17 ft; 27.25 ft overall including bowsprit (sailboatdata). Production paused 1999-2001; an extra 30 gal water tank was optional. Lead ballast.

Engines & parts

Yanmar 2GM / 2GM20F parts: good

Factory standard engine — you entered “Yanmar 2GM20F”

Well supported by Yanmar dealers and aftermarket; stainless mixing elbows that replace the OEM part numbers are widely sold.

Parts sources: Mack Boring & Parts (Yanmar distributor), HDI Marine (stainless exhaust elbows), Parts4Engines

Common problems (2)
  • Nearly blocked mixing elbow exhaust
    Owners find the exhaust port of the mixing elbow almost completely blocked while the engine still runs; a failed U-elbow has also let water into a cylinder and cracked a piston.

  • Noise and vibration from soft mounts engine
    Worn soft engine mounts are a common cause of the vibration owners complain about; better aftermarket mounts are available.

Common problems (3)
  • Leaking heat exchangers and overheating cooling
    Owners report heat exchangers leaking (pressed-in tube joint) and overheating; trapped air in the freshwater circuit and failed impellers are other common causes.
    forums.ybw.com · forums.sailboatowners.com
  • Seawater pump leaks cooling
    The Johnson seawater pump is a frequent leak source, and leaks near the elbow hose can corrode the starter and heat exchanger studs.
    forums.ybw.com
  • Restrictive cast iron elbow exhaust
    The cast iron exhaust riser/elbow clogs with soot, raising back pressure.
