Owners Manual

PASSENGER AND GEAR LOADING

The maximum recommended load includes the 
weight of all persons onboard,  personal effects,  
equipment, cargo from all consumables liquids. 
(eg. water, fuel). When loading the craft never 
exceed the maximum recommended load. This 
may mean having fewer persons on board, then 
recommended on the Australian Builders Plate.

The maximum number of person on board os 
determined by relative standard. Eg AS1799.1/
ABYC. This capacity is determined for calm waters 
as a reduction must be made in adverse weather. 

As passengers occupy different seat positions you 
will notice the boat’s speed change. Passengers 
must never change seat location while the boat is 
moving. As this shift in passenger weight alters the 
planing angle of the hull in much the same manner 
as though the drive unit angle were changed (trim 
was altered).

A shift of passenger or gear load forward or aft will 
often correct minor boat riding deficiencies.

Take care when placing items such as cooler box, 
water jugs, tackle box, anchor, tools, portable fuel 
tanks, etc., to help create more desirable running 
attitudes.

For best boat and motor performance, the 

boat should be trimmed as described in 

“Boat Running Attitude” or to suit the 

prevailing conditions. Passengers 

and equipment should be distributed in the boat 
so it is evenly balanced both front to back and side 
to side.

TRIM ADJUSTMENTS

When trimming the engine from a mid-trim 
position (trim tab in neutral straight fore-and-aft 
position), expect the following results:

Trimming engine up (out) characteristics:

•  Will lift bow of boat, generally increasing top 

speed.

•  Transfers steering torque harder to left on 

installations below 23” (58 cm) transom height.

•  Increases clearance over submerged objects 

(depends on speed/latitude)

•  In excess, can cause porpoising and/or 

ventilation.

•  If trimmed out beyond the water pickup, 

reduced water supply can cause serious 
overheating.

Trimming engine down (in) characteristics:

•  Will help you get on the plane quicker, 

particularly with a heavy load.

•  Usually improves ride in choppy water.
•  In excess, can cause boat to veer to the left or 

right (bow steer).

PASSENGER & GEAR LOADING

INCORRECT 

Overload Forward causes Boat To ‘plow’

CORRECT 

Balanced Load Gives maximum performance

INCORRECT

Overload aft causes Boat To ‘porpoise’

PERFORMANCE

Your boat has been constructed for normal 

boating conditions. Using your boat in 

adverse conditions or outside of its design 

limits could affect it structurally and may 

void your warranty. It is the operator’s 

ultimate decision on what conditions the 

boat is used in.
