- Excessive Price: Typical imports charge 30‑40% above OEM cost, eroding profit margins.
- Sub‑par Material Quality: Cast iron cracks under marine corrosion, leading to frequent replacements.
- Long Lead Times: Overseas shipping adds 45‑60 days, delaying vessel commissioning.
- Limited Customization: One‑size‑fits‑all designs ignore specific engine bay constraints.
- Unclear Certification: Lack of CE, ISO‑9001, or RoHS proof creates compliance risk.
Result: Downtime, higher OPEX, and missed delivery windows.
