IMPORTANT WARRANTY INFORMATION FOR U.S.A. AND

CANADA

Welcome to the Yamaha Family!

Congratulations on the purchase of your new Yamaha marine power. Yamaha is committed to exceptional customer satisfaction, and we want your ownership experience to be a satisfying one. Please read the following warranty information to help ensure satisfaction with your Yamaha.

Yamaha is ready to stand behind your purchase with strong warranty coverage. To be sure you receive all the benefits of warranty, please take the following steps:

1. Be sure your new Yamaha is registered for warranty. Your boat dealer should do this at the time of sale. Make sure your dealer gives you a copy of the completed Yamaha registration card for your records. If you are unsure whether or not your Yamaha is registered, complete the Warranty Registration card found inside the cover of the Owner's Manual.

Mail it to the distributor for the country in which you live (see step 6 for the correct address). If your Yamaha is not properly registered, a warranty repair could be unnecessarily delayed while registration records are checked.

2. Read the Limited Warranty statement which follows these instructions. This warranty applies to Yamaha outboard motors sold in the United States, whether purchased separately or when supplied as original equipment by a boat builder. The terms also apply to original equipment packages sold in Canada, with coverage provided by Yamaha Motor

Canada (see ``Warranty Guide'' for Canadian models). This warranty explains the conditions of the warranty, including the obligations that your dealer and you as the owner have under the warranty. For example, your Yamaha outboard must receive a proper pre-delivery inspection (PDI) by the selling dealer. Failure to take this important step could jeopardize warranty coverage!

3. If you need warranty repairs, you must take your Yamaha outboard to an authorized

Yamaha outboard dealer. Be aware that not all selling boat dealers are authorized

Yamaha dealers. Only authorized dealers have the factory training, special tools, and

Yamaha support needed to perform warranty repairs.

4. If you are away from home, or your selling dealer is not an authorized Yamaha dealer, use the following toll-free numbers to find the nearest Yamaha dealer.

United States Dealer Locations: 1-800-692-6242

Canada Dealer Locations: 1-800-267-8577

62Y-9-18-6 5/16/01 10:28 AM Page 5

5. Your warranty applies specifically to repairs made in the country of purchase. If your

U.S.-purchased Yamaha needs warranty service while in Canada, or your Canadian purchased Yamaha needs service while in the United States, Yamaha will assist the local dealer whenever possible. However, some products available in one country may not be sold or serviced in the other.

6. If you need any additional information about your Yamaha or warranty coverage which your dealer cannot provide, please contact us directly.

WARRANTY QUESTIONS AND ANSWERS

Q.

What costs are my responsibility during the warranty period?

A.

The customer`s responsibility includes all costs of normal maintenance services, non-warranty repairs, accident and collision damages.

Q.

What are some examples of ``abnormal’’ strain, neglect, or abuse?

A.

These terms are general and overlap each other in areas. Specific examples include:

Running the machine out of oil, operating the machine with a broken or damaged part which causes another part to fail, damage or failure due to improper or careless transportation, and/or tie down. If you have any specific questions on operation or maintenance, please contact your Yamaha outboard dealer for advice.

Q.

Does the warranty cover incidental costs such as towing or transportation due to a failure?

A.

No. The warranty is limited to repair of the machine itself.

Q.

May I perform any or all of the recommended maintenance shown in the Owner’s Manual instead of having the dealer do them?

A.

Yes, if you are a qualified mechanic and follow the procedures specified in the Owner’s and Service Manuals. We do recommend, however, that items requiring special tools or equipment be done by a Yamaha outboard dealer.

Q.

Will the warranty be void or canceled if I do not operate or maintain my new outboard exactly as specified in the Owner’s Manual?

A.

No. The warranty on a new outboard cannot be ’’voided`` or ’’canceled``. However, if a particular failure is caused by operation or maintenance other than as shown in the Owner’s Manual, that failure may not be covered under warranty.

Q.

What responsibility does a Yamaha outboard dealer have under this warranty?

A.

Each Yamaha outboard dealer is expected to:

1. Completely set up each outboard he sells prior to delivery.

2. Explain the operation, maintenance, and warranty requirements to your satisfaction at the time of sale, and upon your request at any later date.

In addition, each Yamaha outboard dealer is held responsible for his setup, service and warranty repair work.

Q.

Is the warranty transferable to second owners?

A.

Yes. The remainder of any existing warranty can be transferred upon request. The unit has to be inspected and re-registered by an authorized Yamaha outboard dealer for the policy to remain effective.

IMPORTANT WARRANTY INFORMATION

IF YOU USE YOUR YAMAHA OUTSIDE U.S.A. OR CANADA

Welcome to the Yamaha Family!

Congratulations on the purchase of your new Yamaha marine power. Yamaha is committed to exceptional customer satisfaction, and we want your ownership experience to be a satisfying one. Please read the following warranty information to help ensure satisfaction with your Yamaha.

This model was manufactured as a U.S.A. specification model, and the warranty statement shown in this manual is for market. To receive the benefits of the warranty that applies to the country in which you use your Yamaha, please note the following information.

1.

The warranty on this model is the same as equivalent models sold in the country where you will receive service. If you need more information about your warranty coverage or your Yamaha outside the U.S.A. or Canada, please contact an authorized Yamaha dealer in your country.

2.

Keep a copy of your sales contract or invoice for the purchase of your Yamaha and present it if you need warranty repairs. This document should show the date of purchase, which is important evidence the repairing dealer will need to be sure your Yamaha is covered by warranty.

3.

If your Yamaha needs warranty repairs, contact an authorized Yamaha dealer in the country where you are. He will explain how to get warranty service in that country.

4.

This Yamaha model may not be sold in some countries. Therefore, in some cases your local dealer may not have all the parts or service information he may need, which may unavoidably delay repairs. If this happens, we thank you for your understanding and assure you we will attempt to resolve the situation as quickly as possible.
