It's also important that when you put your boat in forward...it goes forward.
Also, when you turn the wheel to the right, it is very important that the boat goes right- not left.
My last Mach did the same thing on the water test. Turn left it goes right and turn right and it goes left. The bad part was that after they fixed it something was broken in the system which caused me to lose my steering and the thing instantly turned hard to the right causing the boat to spin and almost ejected my backseat passenger.
