Tank capacities — where the figures come from

Fuel unknown
“18 U.S. gallons (68 L; 15 imp gal)” — search excerpt, en.wikipedia.org · “18 gal (earlier catalog dispute)” — spec database, sailboatdata.com · “20-gal aluminum tank (earlier catalog dispute)” — review, practical-sailor.com

Unresolved: spec databases and their copies say 18 gal, Practical Sailor says 20, and no brochure or owner's manual figure could be checked. If a C&C brochure gave 15 imperial gallons, both 18 US gal and a rounded 20 could come from it, but that's speculation.
Water 30 gal
“30 U.S. gallons (110 L; 25 imp gal)” — search excerpt, en.wikipedia.org

Only a copy of the spec database's figure agrees. C&C was a Canadian builder, so the gallon unit is uncertain.
Water heater unknown
“A three-burner, propane stove with oven also was standard, as was hot-and-cold pressurized water.” — review, practical-sailor.com

One magazine review (Practical Sailor) says hot and cold pressure water was standard, along with 120 V shore power, but gives no capacity. No second source confirms it, so it isn't shown as standard here.

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 thruster on the C&C 33 Mk II.
Stern thruster not fitted
Nothing was found either way; our earlier figure of none appears to be an assumption.
Steering Edson
“A big Edson destroyer wheel ... Steering is with the standard 36-inch destroyer wheel. Throttle and shift controls are i” — review, practical-sailor.com

Practical Sailor gives a standard 36-inch Edson destroyer wheel on a pedestal with built-in engine controls. It doesn't say whether the mechanism is chain-and-wire or geared, and no Edson data sheet for the 33 Mk II was found; the Edson brand rests on this one magazine.

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

Sources disagree on engines, fuel tank — left blank rather than guessed.

Distinct from the C&C 33 Mk I (1974-77). Practical Sailor says only the forward hull panels are balsa-cored, with the rest solid mat and roving; the larger C&Cs of the period (35, 38, 41, 44) are cored throughout. Standard fin keel about 6.3 ft; a keel/centerboard version (board inside a shallow keel, 4.33 ft up / 6.5 ft down) was offered. Shroud chainplates are tied to the hull by stainless rods. Fuel capacity and engine hp are disputed (see disputed). Practical Sailor says "over 200" were built; sailboatdata gives exactly 200.

Engines fitted

Yanmar 2GM — 20 hp, diesel, single standard
Wikipedia (Mark II, 1984-88): fitted with a Yanmar 2GM diesel, quoted at 20 hp. The 2GM family was rated 15-18 hp, so the hp figure may be rounded; only one source read.

Generator

No source mentions a generator for the C&C 33 Mk II.

Known problems for this model

Keel smile / keel bolt corrosion hull
The bolted external lead keel can work loose and show a crack at the hull joint, letting water reach the bolts; inspect or drop the keel before purchase and re-torque the bolts periodically.
practical-sailor.com
Rudder and skeg condition steering
The rudder is glass over a welded stainless web on a stainless stock, with a small skeg ahead; inspect both carefully.
practical-sailor.com
Shift cable adjustment and clutch wear engine
An owner reported premature clutch failure from a badly installed and adjusted shift cable, so check the transmission cable setup.
practical-sailor.com
Tight engine compartment engine
The Yanmar 2GM fits tightly, though access is available from the companionway steps, side panels and the cockpit locker.

Engines & parts

Yanmar 2GM / 2GM20F parts: good

Factory standard engine — you entered “Yanmar 2GM”

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.

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.
