BASIC OPERATION
Shifing Gears
When shifting gears, always move the control lever smoothly  
into gear. Do not hesitate. Slow gear engagement could damage 
the shifting mechanism in the transmission.
NOTE: When shifting from forward to reverse or reverse to forward, 
be sure to stop the control lever in the neutral position and  
allow the engine to fall between 600-800 RPM before completing  
the shift.
A one-hand, single-lever control operates as both a gear shifter 
and a throttle. The lever automatically locks in the neutral position 
(straight up and down) for safety. The lever can be moved from 
neutral only by raising the umbrella lifter under the ball knob. 
Shifting is accomplished by moving the lever forward or backward. 
Center (straight up) is neutral. Moving the lever forward engages 
the running gear; moving it back from center puts the drive train 
into reverse. 
Never attempt to shift without the engine running! This causes 
excessive wear to the shifting mechanism and may negatively 
aect control of the boat.
During regular warm-up of the engine, it is possible to temporarily 
increase the engine RPMs without moving the boat. To accomplish 
this, push in the button located at the bottom of the shift/throttle 
lever with one hand and pull up the “umbrella” (umbrella lifter 
under the ball knob). Move the lever to desired position and then 
simultaneously release the button and umbrella. The engine will 
run with increased RPMs and can be increased or decreased by 
moving the lever. Returning the handle to the neutral position will 
bring the system back to neutral and reduce the engine RPMs to 
preset levels. This function should be done sparingly. Over-revving 
the engine for any extended period can cause undue wear and tear 
on the engine. Avoid advancing to wide-open-throttle and holding 
the RPMs at that level.
Under Way
If the oil pressure gauge indicates low or no oil pressure, 
immediately stop the boat as outlined below and check the oil 
level. If the temperature gauge indicates overheating, stop the 
boat when it is safe to do so as outlined below and check the raw 
water system for blockage. (See the Boat Operations and Care and 
Maintenance sections of this Owner’s Manual for directions on 
how to properly check for the blockage.) DO NOT operate the boat 
until the cause for the warning has been found and corrected. 
 
Continued operation after the warning light has illuminated may 
cause severe engine damage. This will void your warranty.
