ATTENZIONE
3.7 General recommendation
It is very important to check the absence of air in the system before using the boat! We recommend trying
to manually move the engine towards port and starboard, making sure that there is no movement of the
cylinder body on the main cylinder shaft.
If the cylinder body moves more than 1/6 inches (15mm), there is still air in the system. The air presence in
the system can cause bad responses to the controls and so it can cause damage, injuries or death.
