115 HP EFI 4-stroke outboard motors, it is important to distinguish between the standard factory limited warranty and any promotional extended coverage that may be available at the time of purchase.
Below is a breakdown of how the major manufacturers typically structure their warranties for recreational use.
General Warranty Overview by Manufacturer

| Mercury | 3 Years | Coverage includes the engine; specific corrosion coverage may vary based on model/region. |
| Yamaha | 3 Years | Standard limited warranty; requires dealer registration and PDI (Pre-Delivery Inspection). |
| Suzuki | 5 Years | Often advertises a 5-year limited factory warranty as a standard offering for many models. |
Critical Warranty Considerations
1. Commercial vs. Recreational Use
Most manufacturers differentiate strictly between these two categories. If you are operating these motors as part of your business inventory or using them for commercial purposes, the standard recreational warranty will likely not apply. Commercial warranties are typically much shorter (often 1 year) and carry different maintenance stipulations.
2. The Role of the Dealer (PDI & Registration)
Your warranty coverage is almost never automatic. It is contingent upon the selling dealer performing the following:
-
Pre-Delivery Inspection (PDI): This is a mandatory checklist to ensure the motor is rigged, lubricated, and operating within factory specifications.
-
Formal Registration: The dealer must register the engine with the manufacturer via the engine’s serial number. If you are buying these motors as stock for Buy Mustang parts Ltd, you must ensure that your dealership or the supplier has processed this registration.
3. Maintenance Requirements
Manufacturers reserve the right to deny warranty claims if you cannot provide proof of scheduled maintenance.
-
Service Records: Keep meticulous records of all oil changes, filter replacements, and seasonal services performed at the recommended intervals (typically every 100 hours or annually).
-
Use of OEM Parts: While the “Magnuson-Moss Warranty Act” in the US generally prevents manufacturers from voiding warranties based solely on using aftermarket parts, using genuine OEM parts (like those from Yamaha or Mercury) is the safest way to ensure claims are approved without dispute.
4. Transferability
If you plan to sell these motors (or boats rigged with them) to end-users, note that:
-
Most manufacturers allow the transfer of the unexpired portion of the factory warranty to a subsequent owner.
-
The process usually requires re-registering the product with the manufacturer, which may involve a fee or a check by an authorized dealer to verify the engine is in good working order.
Pro-Tip for Inventory Management:
Since you are managing a business, if you are selling these motors, clearly communicate the start date of the warranty to your customers. Customers often assume the warranty starts when they buy the boat from you, but for many, it officially starts the moment the engine is “put into service” or registered by the initial dealer.
