Broken gear teeth from the clutch mechanism of a marine sterndrive unit were analyzed and determined to be a result of long-term wear leading to fatigue cracking of the gear teeth.
Localized corrosion to carbon steel boiler tubes was the result of localized boiling and scouring of protective oxides on the tube wall. Metallurgical and chemical analysis revealed no indication of stress-induced failure.
