Boating Experience
If this is your first boat or if you are changing to a type of boat you are not familiar with, for your own comfort and
safety, get handling and operating experience before assuming command of your boat.
Take one of the boating safety classes offered by the U.S. Power Squadrons or the U.S. Coast Guard Auxiliary. For
more course information, including dates and locations of upcoming classes, contact the organizations directly:
• U.S. Power Squadrons: 1-888-FOR-USPS (1-888-367-8777) or on the Internet at: http://www.usps.org
• In Canada, for the CPS courses call 1-888-CPS-BOAT.
• U.S. Coast Guard Auxiliary: 1-800-368-5647 or on the Internet at: http://www.cgaux.org
Outside the United States, your selling dealer, national sailing federation, or local boat club can advise you of local
sea schools or competent instructors.

jurisdiction and could expose you and other people to the danger of bodily injury or accidental death.
• Follow the instructions provided in the Cruiser & Yacht Owner’s Manual, this supplement, the engine owner’s
manual, and all accessory literature.

• If you choose to install a different engines or add accessories that may affect your boat’s running trim, have a
trained marine technician perform a safety inspection and handling test before using your boat again.
• The engines and accessories on your boat have their own manuals. Read these manuals before using the engines
and accessories.
Unless noted otherwise, all engine and accessory literature referred to in this Owner’s Manual Supplement is
included in your owner’s packet.
While the topics listed below may be included in this Owner’s Manual Supplement and in the Cruiser & Yacht
Owner’s Manual, always refer to the engine manual first for specific information on these important subjects:
Propellers
• Keep the propellers in good repair and at the correct pitch for your particular situation.
• A slightly bent or nicked propeller will adversely affect the performance of your boat.
BEFORE starting or working on your engine(s), read the engine manual.
NOTICE
BEFORE using the accessories on your boat, read the accessory manuals.
NOTICE
BEFORE storing your boat, refer to your engine and accessory manuals for storage/winteriza-
tion instructions.

ENGINE DAMAGE HAZARD!
The factory standard propellers may not be the best for your particular boat and load condi-
tions. Refer to the engine manual for engine RPM ratings. The engines should reach, but not
exceed the full rated RPM when full-throttle is applied.
Immediately contact your local Bayliner dealer if:
• The engines cannot reach the full rated RPM when full-throttle is applied, or;
• The engines exceed the full rated RPM when full-throttle is applied.
CAUTION !

Special Care for Moored Boats
• Whether moored in saltwater or freshwater, your boat will collect marine growth on its hull bottom.
• This will detract from your boat’s beauty, greatly affect its performance, and may damage the gel coat.
There are two ways to slow marine growth:
1. Periodically haul your boat out of the water and scrub the hull bottom with a bristle brush and a solution of soap
and water.
2. Occasionally reapply the anti-fouling paint on your hull bottom. How often your hull needs new anti-fouling
paint depends on many factors. Ask your selling dealer or local marina for advice.
Sacrificial Anode (Zinc)
Your boat is equipped with a sacrificial anode (zinc) to pro-
tect underwater metal parts from excessive deterioration.
Check the zinc regularly and replace it if it has deteriorated
more than 70%.
Many factors affect the rate at which the zinc deteriorates,
including:
• Water temperature
• Salinity
• Water pollution
• Stray electrical current
Stray electrical current from your boat, another boat, or the
dock may cause complete deterioration of the zinc in just a
few weeks. If there is rapid zinc deterioration, measure the
electrolytic corrosion around your boat with a corrosion
test meter.
Boats Without Bottom Paint:
• To help seal the hull bottom and reduce the chance of gel coat blistering while your boat is
moored, apply an epoxy barrier coating.
• The barrier coating should be covered with several coats of anti-fouling paint.
• Many states regulate the chemical content of bottom paints in order to meet environmental
standards. Check with your local dealer about recommended bottom paints, and about the
laws in effect in your area.
NOTICE
• Do NOT paint between the zinc and the metal surface it contacts and do NOT paint over
the zinc.
• If the zinc is NOT bonded correctly, it will NOT provide protection.
