The description and specifications contained herein were in effect at the time this guide was approved for printing. Mercury Marine, whose policy is one of continuous improvement, reserves the right to discontinue models at any time, or to change specifications or designs, without notice and without incurring obligation. It in- corporates numerous design features to assure operating ease and durabil- ity. With proper care and maintenance, you will thoroughly enjoy using this product for many boating seasons. To ensure maximum performance and carefree use, we ask that you thoroughly read this manual. A lanyard stop switch can also be installed as an accessory. The purpose of this switch is to turn off the engine ignition whenever the operator (when attached to the lanyard) moves far enough away from the operator’s position to activate the switch. This would occur if the operator falls or moves within the boat a sufficient distance from the operator’s position. Know and obey all nautical rules and laws of the waterways. Boat operators should complete a boating safety course. Courses are offered in the U.S.A. Tell someone where you are going and when you expect to return. Passenger boarding. Stop the engine whenever passengers are boarding, unloading or are near the back (stern) of the boat. Just shifting the drive unit into neutral is not sufficient. Watch fallen skiers. 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. 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. This limit is slightly above the normal operating range of the engine and is designed to help prevent damage from ex- cessive engine RPM. Since air (containing oxygen) gets thinner as eleva- tion increases, the engine begins to starve for air.

Humidity, baromet- ric pressure and temperature do have a noticeable effect on the density of air. 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. After recovery, immediate service by an Authorized MerCruiser Dealer is required to prevent serious damage to power package. CA19 Trailering Boat Boat can be trailered with drive unit in “up” or “down” position. Ade- quate road clearance is required between road and gear housing skeg when trailering with drive unit in “down”. This “Stolen Motor” information is placed into a file at Mercury Marine to aid authorities and dealers in recovery of stolen motors. Use of replacement electrical, ignition or fuel system compo- nents, which do not comply to these rules and regulations, could result in a fire or explosion hazard and should be avoided. 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. 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. The boat owner is responsible for any charges. Change crankcase oil and filter.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.

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. 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. All controls feature an integral safety switch that allows starting engine in NEUTRAL only. Also, all controls may not have all features shown.Move lever forward to shift to FORWARD gear. Move lever backward to shift to REVERSE gear. Lever in full vertical position shifts to NEU- TRAL. Also, the Power Trim system “Trailering” feature allows the op- erator to raise and lower the drive unit for trailering, beaching, launching and low speed (below 1200 RPM engine speed), shallow water operation. Should this happen, release button and allow motor to cool for about one minute. Circuit breaker will reset and Power Trim operation may be resumed. Should this happen, release button and allow motor to cool for about one minute. Should this happen, release button(s) and allow motor to cool for about one minute. 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). Be prepared to decrease engine speed to 1000-1500 RPM as soon as engine starts. F Turn ignition key to START Release key when engine starts and allow switch to return to RUN position.Turn battery Check Turn bat- switch ON, if so. 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:. We do not know what percentage your boat’s fuel system will withstand. Contact your boat manufacturer for specific recommendations on the boats fuel system components (fuel tanks,fuel lines, and fittings). See “Cold Weather or Extended Storage” later in this manual. 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. IMPORTANT: Refer to MAINTENANCE CHART for complete listing of all scheduled maintenance to be performed.Areas where temperatures generally do not go below 32 F (0 C), rust inhibitor and tap water is acceptable. SCHEDULED MAINTENANCE TO BE PERFORMED BY DEALER TASK INTERVAL 20-Hour Checkup (See At First 20 Hours of Operation NOTE 1) Seawater Pickup Pump Whenever Insufficient Seawater Flow -Disassemble and is Suspected. SCHEDULED MAINTENANCE TO BE PERFORMED BY DEALER TASK INTERVAL Engine Alignment - Check Every 100 Hours of Operation or Engine Coupling, Once Yearly, Whichever Occurs Universal Joint Shaft First. Splines - Lubricate Universal Joint Cross Every 200 Hours of Operation or. SCHEDULED MAINTENANCE TO BE PERFORMED BY DEALER TASK INTERVAL Saltwater use: Every 50 Hours of Engine Exhaust System- Operation or 60 Days, Whichever Inspect for external Occurs First damage,deterioration Freshwater use: Every 100 Hours and restrictions. Allow approximately five minutes for oil to drain into oil pan. Boat must be at rest in water. Remove dipstick. Wipe clean and reinstall fully into dipstick tube. Remove dipstick and observe oil level. Oil level must be between FULL and ADD. Lubri- cant should be changed before placing boat in storage. Power Trim or Power Steering fluids do not require changing. Coolant in closed cooling system should be changed at specified in- tervals by your Authorized MerCruiser Dealer.

Remove OIL VENT screw and sealing washer. Allow oil to drain completely. Gasoline is extremely flammable and highly explosive under certain con- ditions. Be sure ignition key is OFF. Do not smoke or allow spark or open flame in area when changing fuel filter. Wipe up any spilled fuel immediately. WARNING Do not grease steering cable while extended. Hydraulic lock could occur and cause loss of steering control. NOTE: If steering cable does not have grease fitting, inner wire of cable cannot be greased. For propeller shaft lubrication, see PROPELLER.A minimum of 55 lbs. ft. (75 N m) torque is required. CB157 REMOVAL (BRAVO THREE) Place wood block between propeller blades and anti-ventilation plate to prevent rotation. Turn aft propeller shaft nut counterclockwise to remove nut. Slide forward thrust hub onto propeller shaft, with tappered side toward propeller hub (Toward end of shaft). To avoid possible injury, remove pro- peller. CAUTION Do not run engine above 1500 RPM when flushing.All drive belts must be periodically inspected for condition and ten- sion. Perform the following inspections of alternator drive belt, power steering pump drive belt (if so equipped) and seawater pickup pump drive belt. B Install new anodes and tighten securely. CB329 NOTE: Bravo Three Models may be equipped with one or two pro- peller anodes. Propeller Anodes (Bravo Three Model) - are located in the splash plate, just above the propellers. To replace the propeller anodes: A Remove the bolts that secure the anodes to the splash plate. Painting Boat Hull or Boat Transom: Antifouling paint may be applied to boat hull and boat transom but you must observe the fol- lowing precautions: IMPORTANT: DO NOT paint anodes or MerCathode System ref-. Recharge every 30 to 45 days, or when specific gravity drops below battery manufactur- er’s specifications. Refer to specific instructions and warnings accompanying your bat- tery.

If this information is not available, observe the following precau- tions when handling a battery. Free of distortion, nearly flat where it contacts water. Straight and smooth, fore and aft. ANTIFOULING PAINTS See Antifouling Paint recommendations and related information on previous pages. CAUTION DO NOT operate engine without water flowing thru seawater pickup pump, as pump impeller may be damaged and subse- quent overheating damage to engine or stern drive unit may re- sult. While operating en- gine at fast idle (1000-1500 RPM), fog internal surfaces of engine by squirting approximately 8 ounces (227 g) of Quicksilver Storage Seal (or if not available, SAE 20W motor oil) into carburetor bores. Stall engine by squirting last 2 ounces (57 g) of Storage Seal (or oil) rapidly into carburetor. Make sure that speedometer pitot tube, trim tab cavity vent hole, and trim tab cavity drain passage are unobstructed. After cooling system has been drained completely, install drain plugs, reconnect hoses and tighten all hose clamps securely. CAUTION If boat is to remain in water after draining seawater inlet hose must be removed and plugged to prevent a siphoning action that may occur allowing seawater to tow from the drain holes or removed hoses. Crank engine over slightly with starter motor to purge any water trapped in seawater pickup pump. Do not allow en- gine to start. CB309 Power Package Recommissioning WARNING To prevent possible injury or damage to equipment, do not in- stall battery until all maintenance has been performed on en- gine. Check that all cooling system hoses are connected properly and hose clamps are tight. Turn switch on. Remote control not in neu- Position control lever in tral position. neutral.

I have noticed many posts lately with questions regarding information that is addressed in this manual. Wondering if you want to add this to the Archives for all to use. Yes there are other manuals on here. Didn't realize it was an issue. Thanks LaRea, Rob I agree with LaRea and should be careful. The forum's policy is simple: don't post copyrighted material unless you own the copyright. In a previous life, I used to watch people on the internet steal and give away songs that my band had performed and was trying to sell. That gave me a new perspective on theft of intellectual property. And now I have officially beaten this topic to death. I am not saying we should violate a forum policy just that its an easy thing to obtain on the internet. I'm all about protecting IP, however the amount Merc charges me for all the OEM parts I buy from them despite their many defective systems they have designed over the years and only address through TSB's on the owners dime, I will poach their service manual and not feel bad about it. It borderline forces the consumer to be a mechanic and fix their products. The ethical thing would be for them to give us the manual and not even make us search. I did buy one for my Merc 15hp outboard though. You now own that license, and it is perfectly legal to post a copy. So if the forum rules can be interpret ownership to mean you are the owner or own a license to copy.If the forum rules do not allow us to provide copies, when we have the right (license) to, then the forum rules need to be updated (they are old and obsolete).

We need to make sure we do not get stuck with draconian rules, or this site will become obsolete, as consumers have the choice and will leave.As you or anyone else would. Now we all know. MarB what happened to Blackberry. You mentioned it? Like I said, he's a solid forum member doing what we all do here -- helping fellow boaters. A friend once gave me a hard drive with about 2000 bootleg songs from every artist you could imagine. At first, it was great. I ended up deleted them. So, yeah I guess I'm more sensitive to this topic than most people. And now I have really, truly beaten this topic to death. They thought they had the best product out there, and along came apple and samsung who took over their market share. The company was worth billions, and they didn't listen to their customers, so people slowly switched from blackberry to apple and android. Then one day they realized they lost like 30 market share, and when the market got hold of that news, they dumped stock. The company almost folded. I believe they were bought out for a few hundred million, but a fraction of what they used to be worth. Moral of the story, LISTEN to customers, and stay relevant. If you're not relevant, the world owes you nothing, and will move on, leaving you in the dust. The world has no sympathy for stubborn old ideas. If you're not relevant, the world owes you nothing, and will move on, leaving you in the dust. The world has no sympathy for stubborn old ideas. Powered by Vanilla.
