Thank You for Choosing a
Williams Dieseljet
This owner’s handbook has been compiled to help you operate your Dieseljet with safety and
pleasure. It contains details of the boat and equipment fitted, together with information on its
operation and maintenance. Please read it carefully, along with the Yanmar Engine manual,
and familiarise yourself with the boat before using it.
The Williams Dieseljet uses water jet propulsion. If this is your first boat or you are changing
to a type of boat you are not familiar with, for your own safety, please ensure that you obtain
handling and operating experience before assuming command of the boat. Your dealer,
national sailing federation or yacht club will be pleased to advise you of sea schools, or
competent instructors.
To take advantage of the Yanmar Engine Warranty, please remember to register your engine
online at www.yanmarmarine.com.
The Dieseljet range are high performance boats. Williams recommends a minimum
standard of RYA level 2 or ICC (International certificate of competency) is attained by
the operator prior to taking control of this boat. This manual assumes the operator has
acquired this standard of qualification and possesses knowledge of basic seamanship.
Please keep this handbook in a secure place and hand it to the new
owner if you sell the boat.
