Engine Warranty


For Viper® Engines:

Ardisam, Inc. (Ardisam) warrants this engine under a five-year limited warranty to be free from defects in the material or workmanship or both for a period not exceeding sixty consecutive months from the date of original purchase by the first retail consumer. “Consumer use”, means personal recreational use by a retail consumer. “Commercial use”, or “commercial application“, means all other uses, including use for commercial, income producing or rental purposes. Once a product has experienced commercial use, it shall thereafter be considered as a commercial use product for the purpose of this warranty. This warranty applies to the original owner who provides a proof of purchase. This warranty is not transferable. Any unit used in a commercial application is covered for a period of 90 days after purchase by the first commercial end user. For the warranty to be valid, the product must be registered online within 30 days of purchase, or the warranty card must be filled out and received by Ardisam within 30 days of purchase. Ardisam shall not be obligated for transportation charges that result from repair or replacement under the terms of this warranty. Transportation charges are the sole responsibility of the purchaser.

This limited warranty applies to defects in the material or workmanship of the engine only and does not apply to the product to which the engine is mounted. Parts applied to the external engine like clutches, pulleys, belt engagement items are subject to the warranty of the product to which the engine is mounted. Damage resulting from acts of God (or other events beyond Ardisam’s control), accidents, and vandalism, is excluded. This warranty applies only to engines which have not been subjected to negligent use, abuse, or misuse, including but not limited to overload, improper installation, alteration, uses other than those indicated in the product manual, improper storage, operating engine above recommended maximums stated in the manual, operating engine with fuel:oil mixture other than that which is stated in operator’s manual (2-cycle) or with insufficient, contaminated, or incorrect grade of oil (4-cycle), using gasoline with greater than 10% ethanol, contaminated gasoline, dirt ingestion due to improper air filter maintenance or installation, overheating resulting from engine airflow obstructions such as dirt and vegetation, improper tension of belts creating excessive force on crankshaft, excessive vibration causing loose hardware, unbalanced items attached to the crankshaft, failure to perform periodic maintenance as specified in the manual, or use of unauthorized parts or repairs performed at unauthorized service centers.

This warranty excludes parts that are worn or damaged due to normal wear such as spark plugs, recoil ropes, fuel filters, and bearings. Routine maintenance items such as filter elements, O-rings, seals, lubricants, and tune-ups, as well as, natural fading or peeling from normal deterioration due to weather elements, sea water, and chemicals are also excluded. All parts specified in the “Emissions Control Warranty” contained in the retail package will follow the terms of that agreement and are not included as part of this warranty. There is no other express warranty. Implied warranties, including those of merchantability and fitness for a particular purpose, are limited to one year from purchase, or to the extent permitted by law. All other implied warranties are excluded. Liability for incidental or consequential damages are excluded to the extent exclusion is permitted by law. Ardisam does not assume, and does not authorize any other person to assume for Ardisam, any liability in connection with the sale of Ardisam products. To be at “No Charge,” warranty work must be sent directly to and performed by Ardisam or an Ardisam Authorized Warranty Service Facility. To obtain warranty service and/or replacement instructions, contact the Ardisam Customer Service Department at 800-345-6007. If you choose to ship your product to Ardisam for warranty repair, you must first have prior approval from Ardisam by calling the Ardisam Customer Service Department for a return material authorization number (RMA#). Under these circumstances, all items must be shipped prepaid. Ardisam will, in its discretion, at no charge, repair or replace any defective part to which this warranty applies. Ardisam retains the right to change models, specifications and price without notice. Ardisam shall not be obligated to ship any repair or replacement product to any location outside of the United States of America or Canada. Some states and countries do not allow the limitations on how long an implied warranty lasts, or the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state and country to country.

This warranty applies to all Viper Engine products purchased on or after 03/15/2017. Customers that purchase a unit prior to this date should refer back to the original Owner's Manual provided with the product. For additional questions or concerns, please contact our Customer Service Department.
