Engines
Proper engine maintenance is essential to
the performance and reliability of your out-
board engines. Maintenance schedules and
procedures are outlined in your engine own-
er’s manual; follow them exactly.
Flush the system when the boat is out of the
water. Flush daily if used in saltwater.
The age of the gasoline in your tank can affect
engine performance. Chemical changes
occur as the gasoline ages, causing deposits
and varnish in the fuel system and reducing
the octane rating of the fuel. Degraded fuel
can damage the engine and boat fuel tank
and lines. If your boat does not require at
least one full tank of fresh fuel a month, add
a fuel stabilizer to the gasoline to protect the
fuel from degradation. Use only a fuel sta-
bilizer recommended by your Tiara Yachts
dealer or the engine manufacturer. Operate
the boat at least 15 minutes after adding the
stabilizer to allow the treated fuel to reach the
engine. Your dealer or engine manufacturer
can provide additional information on fuel
degradation. For more recommendations for
your specific area, check with your local Tiara
Yachts dealer.
Avoid using fuels with alcohol additives. Gas -
oline, extended with an alcohol blend, will
absorb moisture from the air which can reach
such concentrations that “phase separation”
can occur, where the water and alcohol mix-
ture becomes heavy enough to settle out of
the gasoline to the bottom of the tank. Since
the fuel pick-up tube is near the bottom of
the tank, phase separation can cause the
engine to run poorly or not at all. This condi-
tion is more severe with methyl alcohol and
will worsen as the alcohol content increases.
Water or a jelly like substance in the fuel fil -
ters is an indication of possible phase sepa-
ration from the use of alcohol blended fuels.
Contact your Tiara Yachts dealer or engine
manufacturer for additional information
regarding fuels and additives.
Corian Surfaces
Corian
®
is resistant to heat, but you should
always use a hot pad or a trivet with rubber
feet to protect it. Avoid exposing Corian to
strong chemicals, such as paint removers,
oven cleaners, etc. If contact occurs, flush the
surface with water immediately. Soapy water
or ammonia-based cleaners will remove most
dirt and stains from all types of finishes.
DO NOT use the Corian countertop as a cut -
ting board.
Minor damage, scratches, general or chem-
ical stains, scorches or burns and minor
impact marks can be repaired on-site with a
light abrasive cleanser and a product such
as a Scotch-Brite
®
pad. For heavier damage,
light sanding may be necessary. Heavy dam-
age should be repaired by a Corian-licensed
professional.
11.3 Seats and Upholstery
Seat Slides and Swivel Bases
Perform the following periodically:
• Inspect and tighten mounting screws
between seat slides and seat bottom.
• Inspect and tighten the mounting screws
attaching the seat bases to the boat.
• Keep a light film of grease on manual
seat slides.
• Keep a light film of grease on manual
seat-adjusting mechanisms.
• Clean electric seat slides. DO NOT use
harsh chemicals or abrasives. Lubrica-
tion is not required.
Vinyl Upholstery
The vinyl upholstery used on the exterior
seats and bolsters and the cabin headliner
should be cleaned with soap and water peri-
odically. Stains, spills or soiling should be
