Sources disagree on first year — left blank rather than guessed.

All-new design that replaced the earlier C&C 35. Start year disputed (1982 vs 1983); built through 1987. Keel/centerboard version: 4.16 ft up / 6.4 ft down, 12,150 lb displacement, 5,700 lb ballast. Hull coring: owners describe it as a cored boat and Practical Sailor says C&C's 35-foot and larger boats of the period have balsa-cored hulls. Holding 24 gal is owner-reported. Engine hp (27) from a broker listing. Engine access is tight. Tender for its rig; better suited to coastal cruising and club racing than offshore.

Known problems for this model

2 more
  • Mast step rigging
    Owners advise inspecting the mast step; one keel bolt sits under the mast, so keel work requires unstepping.

  • Holding tank leak and shallow bilge plumbing
    One owner found a leak at the top of the holding tank; the shallow bilge (especially on keel/CB boats) lets water spread, and a dripless shaft seal is suggested.

Engines & parts

Yanmar 3GM / 3GM30F parts: good

Factory standard engine — you entered “Yanmar 3GM30F”

Very popular (used 3GM30Fs sell for $3,000+) and supported by a strong parts network. Cylinder head overhauls (valve seals, lapping, injector service) are a common, parts-supported repair.

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

Common problems (2)
  • Overheating at cruise rpm cooling
    The 3GM30F has a known overheating tendency linked to its heat exchanger; owners also trace it to coked elbows, worn impellers, scaled heat exchangers or air in the raw water circuit. Some heat exchangers were replaced under warranty.

  • Mixing elbow corrosion exhaust
    OEM elbows corrode internally and should be inspected or replaced with stainless versions before they let water into the engine.
