JUST WENT TO GO CLEAR THE SNOW OFF MY BOAT AND TRIED USING THE POWER TILT TO LIFT MOTOR(91' EVINRUDE 140 VRO) AND IT STARTS TO LIFT BUT ONLY GOES A FEW INCHES,SO I LIFTED THE MOTOR MANUALLY AND TRIED AGAIN WITHOUT WEIGHT ON IT,THE TILT PART STILL DOESNT LIFT, MOTOR MAKES NOISE BUT DOESNT LIFT.THE MOTOR SOUNDS LIKE ITS RUNNING FULL STRENGTH AS USUAL.BATTERIES ARE FINE, ANY HELP?? IS THIS A POWER TILT MOTOR PROBLEM .....SHOULD I REPLACE IT.. CAN THE MOTORS NOT WORK BECAUSE OF THE COLD?
