gine, propeller-drive boats. A counterclockwise rotation pro-
peller tends to cause the boat to drive to port when going
forward, and to starboard when going backward, with the rud-
der in the straight-ahead position.
At high speed, there is compensation for this effect and it
is virtually non-existent. But, at slow speed–and especially
during backing–the effect can be very pronounced. This is the
main reason most experienced drivers approach with the dock
to the starboard of the boat.
Stopping–or checking headway–is a technique that must
be mastered. With no brakes, reverse must be used to stop the
boat. The momentum of the boat will vary according to the
load. Make it a practice to slow to no-wake speed before shift-
ing into reverse.
When practicing maneuvering techniques, always do so in
open water that is free of traffic. Adequate practice may make
the difference between a pleasureable experience or a damag-
ing–at the least, embarrassing–one.
HIGH SPEED OPERATION
Your MasterCraft boat was designed to be a high-perfor-
mance ski boat. You may have seen professional drivers with
advanced operating skills perform high-speed maneuvers and
on-a-dime turns. DO NOT attempt to duplicate or simulate
these feats. Paid, professional drivers log thousands of hours
on the water and carefully choreograph every move. Plans are
made in advance in the event the routine must be aborted.
Maneuvers of this nature could cause serious injury or death,
as well as damage to your MasterCraft that will not be covered
under warranty.
For the best engine performance and longevity, the wide-
open-throttle (WOT) engine operation must be near the top of,
but within, the specified WOT operating range. To adjust the
WOT operating range, you must select a propeller with the
proper diameter and pitch. The propeller supplied with your
boat was chosen for best all-around performance under aver-
age operating conditions.
Load, weather, altitude and boat condition all affect WOT
engine operation. If you use your boat for several different
applications such as wakeboarding, barefooting and cruising,
it may be necessary to have two or more propellers of different
size and pitch to allow the engine to operate in the WOT range
for each application.
Propping the boat should be done after the engine break-in
and the initial 10-hour dealer check. The boat should be loaded
the way it would normally be for each application. For example,
if you are propping the boat for wakeboarding, fill the ballast
tanks and add the people and gear you would normally expect
to carry in the boat. Take the boat out and after warm-up, run it
at wide-open-throttle and note the maximum RPM. EFI engines
are equipped with RPM limiters to prevent over-revving. Take
note if the RPM limiter is activated.
