Page 7: Lanyard Stop Switch
CAUTION CAUTION-Hazards or unsafe practices which could result in minor personal injury or product or property damage. IMPORTANT: - Indicates information or instructions that are necessary for proper operation and /or maintenance. WARNING The operator (driver) is responsible for the correct and safe operation of the boat, the equipment aboard and the safety of all occupants aboard.
Page 8 As we cannot possibly know of and advise the boating public of all conceivable boat/ power package types and/or poor oper- ating practices, the final decision of whether or not to use a Lan- yard Stop Switch rests with you, the owner/ driver. We strongly recommend that other occupants be instructed on prop- er starting and operating procedures so they will be prepared should they be required to operate the power package and boat in an emer-...
Page 9: Boating Safety And Seamanship
BOATING SAFETY AND SEAMANSHIP Boating safety and seamanship courses are periodically offered by the following national, state and provincial organizations: Coast Guard Auxiliary. Power Squadrons. Red Cross. State or provincial agencies, charged with water safety enforce- ment. In the United States: To help locate the course nearest you, contact Boat/U.S.
Page 10: Water Wisdom
WATER WISDOM Do not overload! Know your boat’s operating and loading limita- tions. Check safety equipment on board. Know your boating area and avoid hazardous locations. Know signs of weather change and avoid foul weather and rough-sea boating. Tell someone where you are going and when you expect to return. Know boating’s “Rules of the Road’’...
Page 11: Conditions Affecting Operation
CONDITIONS AFFECTING OPERATION WEIGHT DISTRIBUTION Positioning of weight (passengers and gear) inside the boat has the following effects: Shifting weight to rear (stern) will: Generally increases speed and engine RPM. At extremes can cause boat to porpoise. Causes bow to bounce in choppy water. Increases danger of following wave splashing into boat when coming off plane.
Page 12: Cavitation
CAVITATION Cavitation occurs when water flow cannot follow the contour of a fast-moving underwater object, such as a gear housing or propeller. Cavitation permits the propeller to speed up, but the boat speed to reduce. Cavitation can seriously erode the surface of the gear hous- ing or propeller.
Page 13: How Elevation And Climate Affect Performance
IMPORTANT: The 350 Magnum engine is equipped with an RPM rev-limiter that is set at 4900 RPM. This limiter is designed to help prevent damage from engine over-speed. When the engine reaches 4900 RPM, ignition spark is turned off. Once the RPM drops below 4600, complete ignition spark resumes.
Page 14 Although some performance can be regained by dropping to a lower pitch propeller, the basic problem still exists. In some cases, a gear ratio change to more reduction is possible and very beneficial. Summer conditions of high temperature, low barometric pressure and high humidity all combine to reduce the engine power.
Page 15: Important Information
CA13 IMPORTANT INFORMATION OPERATION AND MAINTENANCE Owner/Operator Responsibilities It is the operator’s responsibility to perform all safety checks; to en- sure that all lubrication and maintenance instructions are complied with for safe operation and to return the unit to an Authorized Mer- Cruiser Dealer for a periodic checkup.
Page 16: Freezing Temperature Operation
CA15 FREEZING TEMPERATURE OPERATION IMPORTANT: It boat is operated during periods of freezing tem- perature, precautions must be taken to prevent freezing dam- age to power package. Refer to “COLD WEATHER or EX- TENDED STORAGE” for draining instructions. CA17 DRIVE UNIT IMPACT PROTECTION The Power Trim hydraulic system is designed to provide impact pro- tection for drive unit.
Page 17: Attention Required After Submersion
Use extreme caution when operating in shallow water or where un- derwater objects are known to be present. Use extreme care to pre- vent striking submerged object while operating in REVERSE. No im- pact protection is provided in REVERSE. If drive unit should strike a submerged object, stop engine as soon as possible and inspect drive unit for damage.
Page 18: Launching And Boat Operation Care
CA20 LAUNCHING AND BOAT OPERATION CARE CAUTION During launching from a trailer, if the unloading ramp is steep or the trailer bed must be tilted, the boat may enter the water rapidly and at a steep angle. This may force water through the exhaust system into the cylinders. The more weight on the transom, the more likely this is to occur.
Page 19: Replacement Service Parts
CA22 REPLACEMENT SERVICE PARTS WARNING Electrical, ignition and fuel system components on MerCruiser gasoline pow- er packages are designed and manufactured to comply with U.S. Coast Guard rules and regulations to minimize risks of fire or explosion. Use of replacement electrical, ignition or fuel system components, which do not comply to these rules and regulations, could result in a fire or explosion hazard and should be avoided.
Page 20: Do-It-Yourself Maintenance Suggestions
CA23 DO-IT-YOURSELF MAINTENANCE SUGGESTIONS If you are one of those persons who likes to do-it-yourself, here are some suggestions for you. Present-day marine equipment, such as your MerCruiser power package, are highly technical pieces of machinery. Electronic ig- nition and special carburetion provide greater fuel economies, but also are more complex for the untrained mechanic.
Page 21 Also, if you partially disassemble an engine or drive assembly and are unable to repair it, the dealer’s mechanic must reassemble the components and test to determine the problem. This will cost you more than taking it to the dealer immediately upon having a prob- lem.
Page 22: 20-Hour Break-In Period
CA24 20-HOUR BREAK-IN PERIOD IMPORTANT: The first 20 hours of operation is the engine break-in period. Correct break-in is essential to obtain mini- mum oil consumption and maximum engine performance. Dur- ing this break-in period, the following rules must be observed: Do not operate below 1500 RPM for extended periods of time for first 10 hours.
Page 23: 20-Hour Checkup
CA236 20-HOUR CHECKUP After first 20 hours of operation, an Authorized MerCruiser Dealer should be contacted for the following maintenance. The boat owner is responsible for any charges. Change crankcase oil and filter. Check all fluid levels. Cooling System: Inspect all hoses for damage and deterioration; check all hose clamps for adequate tightness.

Page 25: Operation
CA27 OPERATION INSTRUMENTATION The following is a brief explanation of instrumentation typically found on some boats. The owner/operator should be familiar with all instru- ments and their functions on the boat. Because of the large variety of instrumentation and manufacturers, you should have your boat dealer explain the particular gauges and normal readings that will ap- pear on your style gauges.

Page 27: Audio Warning System
CA248 AUDIO WARNING SYSTEM Your MerCruiser power package may be equipped with an Audio Warning System. The audio warning system buzzer will sound if one of the following occur: A Insufficient Oil Pressure B Excessive Engine Temperature C Insufficient Drive Lubricant NOTE: To provide a test of the system, the audio warning buzzer will sound when the ignition switch is first turned to the run position, prior to cranking the engine.

Page 29: Electrical System Overload Protection
CA30 ELECTRICAL SYSTEM OVERLOAD PROTECTION If an electrical overload occurs, a fuse will blow or the circuit breaker will trip open. The cause must be found and corrected before replac- ing fuse or resetting circuit breaker. A circuit breaker provides protection for engine wiring harness and instrumentation power lead.

CA40 STARTING, SHIFTING AND STOPPING WARNING Before starting engine, operate bilge blower for at least five minutes to remove any explosive fumes from engine compartment. If boat is not equipped with a bilge blower, open engine hatch and leave open while starting engine. IMPORTANT: Observe the following: Do not start engine without water being supplied to seawater pickup pump (to prevent pump or engine damage).

Engine damage resulting from use of improper gasoline is considered misuse of engine, and damage caused thereby will not be covered under the limited warranty. Fuel Ratings MerCruiser engines will operate satisfactorily when using a major brand of unleaded gasoline as follows:...
Page 48 The adverse effects of alcohol are more severe with methyl alcohol (methanol) and are worse with increasing alcohol content. WARNING FIRE AND EXPLOSION HAZARD: Fuel leakage from any part of fuel system can be a fire and explosion hazard which can cause serious bodily injury or death.
Page 49: Crankcase Oil
CA43 CRANKCASE OIL To help obtain optimum engine performance and to provide maxi- mum protection, we strongly recommend the use of Quicksilver 4-Cycle Marine Engine Oil.
