Tank capacities — where the figures come from
  • Fuel 40 gal
    “My 382 has a 40 gallon diesel tank under the cabin sole” — owners' association (382), morgan38.org · “fuel tank capacity of 151 L (40 US gal)” — search excerpt, sailcentral.com
    Owners on the Morgan 38 forum describe a fiberglass tank built into the keel under the cabin sole, the same on 382s and late 384s; one gives 40 gal. That agrees with our earlier figure but isn't a builder source.
  • Water 55 gal
    “a freshwater tank of 208 L (55 US gal)” — search excerpt (382), sailcentral.com
    The 55 gal is for the 382; a spec database notes the 1981 update (383) got a larger water tank, but its size wasn't found. This page covers the 382, 383 and 384, so water likely varies by version.
  • Holding unknown
    A 383 owner on the Morgan 38 forum couldn't find the size of the in-keel holding tank in the manual and guessed 15 gal; no figure was found.
  • Water heater engine (Raritan)
    “If money were no object, I would probably replace it with a like kind Raritan. 40 years is a great service life” — owners' association, morgan38.org · “I replaced my original heater two years ago with an Isotherm unit” — search excerpt, morgan38.org
    Owners on the Morgan 38 owners' forum describe roughly 40-year-old original Raritan heaters plumbed to engine coolant; no capacity, no builder equipment list 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
    No source mentions a bow thruster.
  • Stern thruster not fitted
    Nothing was found either way; our earlier figure of none has no source.
  • Steering pedestal cable · Edson
    “I noticed the chain in the Edson steering was cracking; almost to the breaking point in two places!” — owners' association, morgan38.org · “one of the new steering cables in the Edson pedestal ... pulled out” — owners' association, morgan38.org · “I pulled my pedestal and sent it to Edson a few months ago. They took the shafts and gears out of the old pedestal and i” — search excerpt, morgan38.org
    Morgan 38 owners' forum posts describe an Edson pedestal with chain and wire cables over sheaves to a quadrant (a 382 among them), about 22 years old on one boat in 2006; the emergency tiller is hard to use because the rudder post is close to the pedestal. One owner replaced an older non-Edson unit, so a few boats may differ.

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

Sources disagree on engines, notes only value — left blank rather than guessed.

Fin-keel successor to the 1969-71 centerboard Morgan 38. Standard draft 5.0 ft with an optional 6 ft deep keel. The 383 got a taller rig around 1980-81 (year disputed; sailboatdata also mentions a modified rudder and larger water tank), and around 1983 the 384 got a bigger rudder and new interior; Catalina built 24 more before ending production in 1986. Specs shown are the 382. Decks are cored. Ballast is internal lead. Sailboatdata lists 300 382s and about 500 across all versions. Hull material left null because Practical Sailor says some hulls are Airex-cored and others solid.

Engines fitted

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

Engines & parts

Perkins 4.108 parts: good

Factory standard engine — you entered “Perkins 4-108”

Out of production but very well supported. Trans Atlantic Diesels (TAD) sells complete aftermarket rebuild kits (pistons, liners, rings, bearings, gaskets, valves, guides, seals), heads, blocks, crankshafts, genuine Perkins camshafts, rebuilt injection pumps and injectors, Jabsco/Sherwood raw water pumps, heat exchangers, starters, alternators and elbows, plus rebuilt exchange engines. The Westerbeke 4-107/4-108 family and some industrial engines share the base design.

Parts sources: Trans Atlantic Diesels (TAD), Foley Engines

Common problems (1)
  • Rear main (crankshaft) seal leak engine
    The original rope-type rear seal is notorious for leaking and often starts leaking again a few hundred hours after replacement; Foley sells a nylon/Teflon replacement seal meant to cure it, and owners check the crankshaft sealing surface for pitting.

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

Factory common repower engine — you entered “Yanmar 4JH45”

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.

Steering

Edson — Pedestal chain-and-wire steering parts: good

Edson (New Bedford, MA) still sells service parts: chain-and-wire kits, sprockets, idlers, pull-pull conduit steering and internal pedestal parts, and keeps steering data sheets by boat model, many decades old.

Parts sources: Edson Marine (service parts)

Common problems (3)
  • Old or slack steering wire steering
    Edson advises replacing steering wire about every five years, checking tension with the wheel locked, and inspecting under load annually; owners often find decades-old stiff wire.
    usna.edu · youtube.com
  • Lubrication and fastener checks steering
    Chain, wire, sheaves and pedestal bearings need regular oiling or greasing, and clevis/cotter pins and bolts should be checked monthly to avoid failures.
    usna.edu
  • Replacing engine control cables in the pedestal steering
    Swapping throttle/shift cables inside an Edson pedestal is a common owner job requiring removal of the wheel shaft sprocket pin.
    forums.sailboatowners.com

Edson — Traditional geared steerers (worm / rack-and-pinion) parts: good

Edson says its traditional wheels and geared steerers are still available, now built with modern materials; rack-and-pinion steerers are offered for transom-hung and inboard rudders.

Parts sources: Edson Marine (traditional steerers)
