Known problems for this model
-
Cored deck - check around hardware deck
Decks are cored (Practical Sailor describes end-grain balsa with plywood under hardware; a SpinSheet surveyor described plywood core), so moisture-meter the deck around stanchions and fittings.practical-sailor.com · spinsheet.com
-
External 304 stainless chainplates rigging
Chainplates are bolted outside the hull so they are easy to inspect, but they are type 304 stainless; inspect for crevice corrosion at the deck and bolt holes on older boats.practical-sailor.com
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.

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.forums.sailboatowners.com
-
Mixing elbow corrosion exhaust
OEM elbows corrode internally and should be inspected or replaced with stainless versions before they let water into the engine.practical-sailor.com · facebook.com
