Commercial Powertrain & Marine Propulsion FAQ

To guarantee 100% bolt-in compatibility, our engineering team requires your vehicle/vessel identification number (VIN or HIN), the engine block casting number, cylinder head casting number, and transmission tag ID. For marine propulsion, verify whether your vessel uses standard Left-Hand (LH) rotation or counter-rotating Right-Hand (RH) rotation for twin-engine installations. If you are unsure, photograph your data tags and email them to [email protected].

Our Remanufactured Engines (Reman) are precision-machined OEM long blocks reconditioned to zero-hour factory tolerances with new pistons, rings, bearings, camshafts, and gaskets, requiring an exchange core. Our Turnkey Crate Engines are brand-new, complete drop-in assemblies fitted with factory intakes, fuel injection, sensors, and water pumps, fully dyno-tuned and ready for rapid fleet installation without requiring a core exchange.

Yes. All Marine Inboard Engines are engineered for commercial marine use. They feature closed-loop fresh-water heat exchanger systems (or heavy-duty raw-water cooling configurations), marine brass freeze plugs, high-flow seawater circulation pumps, SAE-certified marine spark-arrested ignition, and anti-corrosion marine enamel coatings.

Our Marine & Industrial Generators range from compact auxiliary units to high-output prime diesel generators. Calculate your total continuous running wattage plus peak inductive surge loads (such as heavy refrigeration compressors, winches, or air conditioning systems). Our engineering desk can assist you with single-phase vs. 3-phase load balancing and 50Hz vs. 60Hz frequency requirements.

For individual replacement units, select your assembly directly through our verified catalog checkout. For commercial fleet overhauls, government transport tenders, or shipyard re-powering projects requiring structured billing, email your technical bill of materials to [email protected]. We will generate a formal Pro-Forma Invoice (PFI) with price protection, engine serial reservations, and scheduled freight milestones.

Yes. We offer an unconditional 24-hour order cancellation grace period from your initial purchase timestamp. If your vessel blueprint changes or gear ratio requirements shift, contact our hotline at 831-8934-5490 within 24 hours for a 100% full refund remitted immediately to your original payment platform. Once machinery enters custom timber skid crating and live dyno testing past 24 hours, standard return terms apply.

Every powertrain unit undergoes a mandatory 2 to 4 business day handling and testing window. During this phase, master mechanics execute cold-spin oil pressure verification, dyno testing, hydraulic pressure calibration, and custom ISPM-15 export skid manufacturing before carrier handoff.

Domestic (Indonesia Scope): Delivered within 3 – 6 Business Days via dedicated heavy-freight and RoRo maritime transport across Java, Sumatra, Kalimantan, Sulawesi, and Bali.
International (USA & Worldwide): Standard delivery requires 10 – 15 Business Days via expedited air cargo or ocean container freight to major international seaports and industrial freight terminals.

All engines, Transmissions, and Gearboxes are lag-bolted to heavy-gauge hardwood skids manufactured from ISPM-15 certified heat-treated timber. Bare metal surfaces are hermetically sealed in Vapor Corrosion Inhibitor (VCI) anti-rust bags with industrial desiccants, fully protected against maritime salt spray and transit humidity.

Because our crated powertrains weigh between 150 kg and 1,200 kg, receiving facilities must have an elevated commercial loading bay, a rated forklift (minimum 2.5-ton capacity), or an overhead gantry crane. If your workshop or marina lacks an elevated dock, a hydraulic liftgate trailer must be requested during checkout so the driver can lower the crate to ground level.

Inspect the external timber crate and check the external ShockWatch and Tip-N-Tell sensors before releasing the carrier driver. If visible damage or sensor activation is found, write “DAMAGED – SUBJECT TO INTERNAL INSPECTION” directly on the carrier’s Bill of Lading (BOL). Then, email photographs of the crate and components to [email protected] within 48 hours so our logistics desk can file an immediate cargo insurance claim.

For international shipments outside Indonesia, the buyer acts as the sole Importer of Record. Carboatengine.com freight quotes cover ocean/air transportation, phytosanitary timber certification, and export clearance. Destination import duties, Value Added Taxes (VAT/GST), and local port handling fees are statutory obligations payable by the consignee directly to customs authorities upon arrival.

All commercial transactions, parts valuations, and core deposits on Carboatengine.com are priced and settled exclusively in US Dollars (USD). Accepted payment rails include:
• Direct Bank Wire / Telegraphic Transfers (T/T): Preferred for high-volume fleet orders and corporate purchase orders.
• Commercial Trade Escrow: Offering full milestone release and capital protection for maritime buyers.
• Corporate Credit Cards: Visa, Mastercard, and AMEX with 3D Secure 2.0 multi-factor verification.
• Wise: For direct international digital wire transfers.

For high-value marine engine packages or multi-unit fleet orders, we facilitate settlement through verified commercial trade escrow. Your capital is deposited into a secure third-party escrow account and is only disbursed to Carboatengine.com once the Bill of Lading (BOL) and shipping manifests are formally verified by the escrow agent.

When purchasing a remanufactured long block, transmission, or differential carrier, a temporary core deposit is charged. You have a generous 60-day window from the delivery date of your replacement unit to return the old core. Keep our reusable timber crate intact. Drain all fluids from the old core, bolt it inside the crate, and notify our team. Once received and inspected, your core deposit is 100% refunded with zero administrative fees.

To receive a 100% refund, the returned core must be fully assembled, a like-for-like casting model, 100% drained of motor oil or transmission fluid, and free of catastrophic non-rebuildable damage (such as connecting rod punctures through the cylinder block or cracked transmission bellhousings). Cores with salvageable casting value receive partial credit based on inspection.

We offer a 30-calendar-day return and exchange window from the official invoice date. If an assembly was ordered with an incorrect gear ratio, rotation, or bolt pattern, we will facilitate an exchange. Returned units must be uninstalled, unrun, and securely lag-bolted to the original ISPM-15 wooden skid. Contact [email protected] for a Return Merchandise Authorization (RMA) prior to dispatch.

Our warranty covers internal lubricated rotating components (crankshafts, bearings, pistons, connecting rods, camshafts, and gear sets) against material and assembly defects. Warranty coverage requires that the unit be installed by a certified marine diesel technician or licensed master mechanic adhering to OEM break-in oil and cooling specifications. Failures caused by raw-water pump impeller dry-running, improper oil viscosity, or foreign debris contamination are excluded.
