PERFORMANCE ~
Passenger and Gear Loading ~
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.
WARNING
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.
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).
• Transfers steering torque harder to right (or less to the left).
• Improves planing speed acceleration (by moving tilt pin one
hole closer to transom).
