Import Tips
• Verify engine power rating with manufacturer's spec sheet; customs requires certification that output is measured at propeller shaft and within 111.9-149.2 kW range
• Include marine propulsion certification (e.g
• IMO compliance docs) and ensure engine is not configured for auxiliary/generator use to avoid reclassification
