Commercial Returns, Exchanges & Core Deposit Policy
Purchasing heavy marine propulsion engines, commercial transmissions, and driveline assemblies involves major capital investment. At Carboatengine.com, we provide a structured, transparent 30-day commercial return framework, a streamlined core exchange deposit system, and comprehensive factory warranty coverage for fleet operators, shipyards, and commercial rebuilders worldwide.
1 30-Day Commercial Return & Fitment Exchange Terms
We understand that vessel repowering schedules, commercial fleet overhauls, and shipyard blueprints can encounter unpredicted driveline variables. If an engine block, marine transmission, transfer case, or differential carrier does not match your project requirements, you have a 30-calendar-day return and exchange window from the purchase date on your official invoice.
Return Eligibility Standards
The unit must be uninstalled, unrun, and unmodified. The powertrain assembly must remain free of rust, drained of all test fluids, and securely lag-bolted to its original ISPM-15 certified wooden skid with all protective plugs and manuals intact.
Fitment & Ratio Exchanges
If you ordered an incorrect gear ratio, marine rotation (Standard LH vs. Reverse RH), or bellhousing bolt pattern, our technical team will exchange the assembly. Price differentials are invoiced or credited with zero administrative delay.
Pre-Return Clearance (RMA): All freight returns require a formal Return Merchandise Authorization (RMA) issued by our engineering desk. Contact [email protected] before scheduling freight pickup to ensure proper customs and warehouse manifest routing.
2 Core Deposit & Exchange Return Program
For remanufactured long blocks, commercial transmissions, transfer cases, and differential carriers purchased under an exchange agreement, our core return process protects your capital:
60-Day Core Return Window
You have 60 calendar days from the delivery date of your replacement unit to return the old mechanical core. This provides ample time for your technicians to complete the swap without operational pressure.
100% Full Deposit Refund
Returned cores meeting standard criteria (assembled, like-for-like casting, drained of fluids, free of catastrophic external block fractures) receive a 100% full core deposit refund with zero administrative deductions.
Core Packaging Notice: Core returns must be lag-bolted back inside the reusable heavy-duty timber crate in which your replacement unit arrived. Ensure all transmission fluid or engine oil is completely drained prior to bolting the crate lid to prevent environmental carrier fines.
3 24-Hour Order Cancellation Policy
Commercial powertrain assemblies require extensive preparation, pre-lubrication, dyno testing, and custom timber crating. If you need to cancel an order due to design adjustments or vessel schedule changes, you may cancel within 24 hours of purchase.
Orders cancelled within this 24-hour window prior to final dynamometer sign-off and export crating receive an immediate 100% full refund issued straight to the original payment platform with zero fees.
4 Technical Metrology Inspection & Refund Disbursement
Unlike standard consumer goods, returning a 600-pound engine or marine gearbox involves rigorous engineering inspection upon delivery to our North Jakarta facility:
5-Business-Day Inspection Protocol
Our machinists inspect the assembly for cylinder wall score marks, journal condition, gear tooth pitting, and unbolted accessories within 5 business days of warehouse physical receipt.
Direct Capital Payout Channels
Approved refunds and core deposits are remitted in US Dollars (USD) via your original payment channel: Direct Bank Wire / Telegraphic Transfer (T/T), Commercial Trade Escrow, Wise, or Corporate Credit Card.
5 Step-by-Step Return & Core Dispatch Guide
To ensure smooth return transit and rapid refund disbursement, follow these three steps:
Step 1: Request RMA Number
Email [email protected] with your invoice number, engine/transmission serial tag, and reason for return or core collection.
Step 2: Pack & Secure Crate
Drain all fluids. Bolt the unit to the ISPM-15 wooden skid, seal with the VCI moisture wrap, and affix the provided return freight bill.
Step 3: Carrier Hand-Off
Our logistics desk coordinates carrier freight pickup from your loading dock. Tracking updates are monitored directly by our depot.
6 Commercial Warranty Coverage & Technical Claims
Every powertrain asset distributed by Carboatengine.com is covered by a standard commercial limited warranty against metallurgical flaws, assembly defects, and internal component failure:
• Reman & Crate Engines: Covered for internal lubricated rotating parts (crankshafts, pistons, camshafts, connecting rods, cylinder heads).
• Transmissions & Marine Gearboxes: Covered for gears, shafts, planetary sets, and hydraulic pump assemblies.
• Installation Clause: Units must be installed by a certified commercial marine technician or licensed master mechanic adhering to OEM break-in oil and cooling procedures. Overheating due to raw-water impeller failure or improper dry running is excluded.
