2004 Operator’s Guide 6 HORSEPOWER R4, RL4 Our First Words to the Owner/Operator This Operator’s Guide is an essential part of your Johnson outboard. It contains pertinent information which, if followed, will provide you with a thorough understanding needed for proper operation, maintenance, care and above all safety! The safety section of this Guide comes first because it is our first priority and it should be yours too.
It is strongly recommended that you read this Guide from front cover to rear cover. Following this recommendation will assure the completeness of the information that is essential to your safety, the safety of any passengers and other boaters. An Operator’s Readiness Test has been prepared on the last page of this Guide. Be safe! All passengers should be familiar with the proper operation of your boat and Johnson outboard. Be certain they fully understand and respect the controls and operation. Each operator is responsible for the safety of all passengers and other boaters. Please make safety your first priority and complete a boating safety course through your local Coast Guard, Power Squadron, Red Cross or State Boating Law Agency. The pleasures of owning and operating a Johnson outboard can be significant. We strongly believe the rewards for following our recommendations will be worthwhile.
