e) When inflating, please keep the air pressure balance between air chambers to avoid the damage of
bulkheads.
f) Inflatable boats can be damaged by extreme internal air pressure. Such pressure can be caused by
temperature differences. A boat properly inflated in the morning may become dangerously over-pressurized
as the day warms up. The internal pressure can multiply many times as the surfaces temperature increases
and under such conditions, seams can separate and bonded materials can delaminate. Avoid subjecting your
inflatable to such conditions by relieving pressure in all chambers of your boat as the day heats up or before
leaving the boat exposed to hot midday sun. It is highly recommended that the boat be stored in the shade
or under cover when it is not being used.
g) Using the boat with under inflated tubes may cause serious damage, including transom cracking.
Caution
Do not use a compressed air source to inflate the tube or you may compromise the integrity of the seam or
internal baffles. Seams or baffle rupture due to non-respect of inflation procedure is not covered under the
warranty.
2. Performance
(1) To achieve best performance, the boat must plane. If the boat does not plane you may check the following:
a) Make sure the bilge/ deck is dry, drain the water otherwise.
b) Make sure the tube is correctly inflated.
c) Make sure you have the correct weight distribution. Sea conditions may require passengers to move
forward to the boat to get the boat on plane before they return to their initial positions.
d) Make sure you use a suitable outboard engine for the boat.
(2) The outboard engine plays a big role in the performance of the boat. Please make sure you use a suitable
outboard engine for the boat.
(3) When you drive your boat, you will have to keep the boat balance fore and aft. To achieve that, you will have
to adjust the trim angle of your boat. A properly trimmed hull has two very beneficial results: reduced fuel
consumption and increased speed.
(4) Most outboard engines over 30 horsepower come with a trim and tilt system that is driven by a hydraulic
ram located in the center of the engine mounting bracket. Its function is to raise and lower the engine, and it
is controlled by an "up/down" rocker switch built into the shift and throttle control that is located directly
under your right thumb for ease of access. In the "tilt" mode, the system raises the engine completely out of
the water when not in use. It can also be used to raise the engine when running the boat slowly in very
shallow water to prevent propeller damage.
In trim mode, the system works to adjust the angle of the engine to affect the running angle of the boat. As
the boat increases speed, the engine angle provides the lift necessary to bring the boat on plane for optimal
performance. In the full down position, the engine is in "negative trim", meaning the angle of the engine
shaft and propeller is slightly forward of straight down in relation to the transom. This is the position the
