Propulsion Systems
1.1 General
Your Tiara Yacht is designed to be powered
with outboard engines. The manufacturer of
the outboard engines provides an owner’s
information manual. It is important you read
and understand the information and become
familiar with the warranty, operation, and
maintenance of the engines and drive sys-
tems.
WARNING
!
MOVING PARTS HAZARD
Contact with moving parts can entan-
gle, cut and cause death or serious
injury. DO NOT get close enough
to make contact with any running
machinery moving parts, i.e., engine
or propeller. Contact can result in loss
of body parts, strangulation, burns
and/or severe loss of blood resulting
in death or serious injury.
NOTICE
!
DO NOT attempt to service any part of
the outboard or boat systems unless
you are familiar or qualified to do
so. Do not use parts which are not
designed for a marine application.
NOTICE
!
Use only the fuel recommended by the
engine manufacturer. Use of old, con-
taminated fuel can cause the engine to
malfunction or severe damage.
1.2 Saltwater Application
Each outboard engine is a complete drive
system with the gear case (transmission) for-
ward of the propeller and connected to the
power head with a vertical drive shaft. Other
than the routine maintenance outlined in the
engine owner’s manual, there is little to be
concerned with unless the boat is to be kept
in saltwater for extended periods. Marine
growth will occur when components are left
in the water for extended periods and can
cause poor performance or permanent dam-
age to the exposed components. The type of
growth and how quickly it occurs is relative
to the water conditions in your boating area.
Water temperature, pollution, current, etc.,
can have an effect on marine growth.
Galvanic corrosion is the corrosion process
occurring when different metals are sub-
merged in an electrolyte. Sea water is an
electrolyte and submerged engine compo-
nents must be properly protected. Outboard
engines are equipped with sacrificial anodes
to help prevent galvanic corrosion problems.
The anodes must be monitored and replaced
as necessary. For locations and mainte -
nance, refer to the engine owner’s manual.
When leaving the boat in the water, tilt the
motors as high as possible to decrease the
risk of damage from galvanic corrosion or
marine growth around the cooling inlets, pro-
peller and exhaust ports.
CAUTION
!
DO NOT use copper-based coatings
or any coatings not approved for use
with aluminum. Some paint manufac-
turers claim their paints are safe for
aluminum. Copper components and
copper-based paints can cause severe
corrosion to aluminum. DO NOT use
copper-based paints. Mercury or mer-
cury-based compounds that come
into contact with aluminum will result
in severe corrosion.
