Tank capacities — where the figures come from
  • Fuel 40 gal
    “Fuel Tank: 40 gal (151.42 liters)” — search excerpt (1994), vessel.yachtbroker.org · “40 U.S. gallons (150 L; 33 imp gal)” — spec database, en.wikipedia.org · “37 gallons of fuel” — search excerpt (1995), boattrader.com
    A listing and a spec-database copy give 40 gal; another listing (and a listing site's 1985 boat) says 37. No builder figure was found.
  • Water varies by year
    “40-gallon aluminum potable water tank (an additional 60-gallon fiberglass tank is beneath the saloon sole)” — review, goodoldboat.com · “95 U.S. gallons (360 L; 79 imp gal)” — spec database, en.wikipedia.org · “Fresh Water: 86 gal (325.55 liters)” — search excerpt (1994), vessel.yachtbroker.org · “85 gallons of water” — search excerpt (1995), boattrader.com · “80 gal capacity total in 2 tanks” — search excerpt (1992), grayandgrayyachts.com
    Water tanks differ boat to boat (80 to 100 gal in two or more tanks). Good Old Boat magazine's featured boat had 40 + 60 = 100 gal, and Practical Sailor notes integral liner tanks on early boats. No builder figure settles a standard.
  • Holding unknown
    “Holding Tank: 16 gal (60.57 liters)” — search excerpt (1994), vessel.yachtbroker.org · “a 16-gallon holding tank” — search excerpt (1995), boattrader.com
    Two independent listings (different brokers, 1994 and 1995 boats) agree, and match the 16-gal integral tank in the sister Pacific Seacraft 34's owner's manual. No builder figure for the 37 was checked.
  • Water heater AC + engine · factory option
    “some components ... that should be standard on a boat of this quality, like lightning grounding, hot and cold pressure w” — review, practical-sailor.com · “Six gallon hot water heater from engine heat exchanger or shore power.” — broker listing (1998), denisonyachtsales.com · “Six gallon hot water heater from engine heat exchanger or shore power” — broker listing (1998), blueyonderyachts.com
    Practical Sailor's review says hot and cold pressure water was an option when reviewed. Listings for two different 1998 boats reproduce factory standard-equipment text with a 6 gal heater on engine heat exchanger or shore power, and the builder's late-1990s 34 manual calls heaters standard on all its yachts, so it likely became standard later.

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
    No builder list, review or listing mentions a thruster on the Crealock/Pacific Seacraft 37.
  • Stern thruster not fitted
    Nothing was found either way; our earlier figure of none appears to be an assumption.
  • Steering varies by year
    “with the now-standard steering pedestal in place (the boat was designed for tiller steering)” — review (2000), practical-sailor.com · “Newer boats have wheel steering, but tiller steering was common in the Crealock 37 and in older Pacific Seacraft models,” — review (1989), goodoldboat.com
    Two magazines agree the boat was designed for a tiller and early boats (a 1989 example) often had one, while wheel steering on a pedestal later became standard. The changeover year and the pedestal maker aren't stated.

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

Sources disagree on ballast, draft, deck construction, hp (Yanmar 4JH2E) — left blank rather than guessed.

Built as the Crealock 37 from 1978, by Pacific Seacraft from 1980. Sloop, cutter or yawl; cutter most common. Engines ranged from a 24 hp Volvo in early boats to a 50 hp Yanmar in later ones. Solid hull (balsa/foam hull core was a rare option). Fin keel with skeg-hung rudder; external chainplates.

Engines fitted

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

Generator

No builder or review source mentions a generator; one 1998 listing shows a 2500 W generator (likely portable) and another only a wind generator.

Known problems for this model

Engines & parts

Yanmar 4JH series (4JH, 4JH2/3/4, -E, -TE, -HTE) parts: good

Factory standard engine — you entered “Yanmar 4JH2E”

Widely used and fully supported by Yanmar dealers and distributors; the mixing elbow is treated as a consumable part.

Parts sources: Mack Boring & Parts (Yanmar distributor), Yanmar USA genuine parts

Common problems (1)
  • Mixing elbow failure exhaust
    The exhaust mixing elbow on 4JH engines pits and fails, sometimes within a few hundred hours; owners treat roughly 1000 hours as a practical life and inspect the elbow-to-manifold joint for salt weeping.
