Hello,<br /><br />I have a boat with a evinrude-60HP-VRO motor of 1991,<br />and this summer it had a failure.<br />Once it was working fine during 3 - 5 minutes, there<br />were 3 or 4 partial motor failures. In this moment, if<br />we made the motor working in low speed, the motor is<br />still working. If we made the motor working in high<br />speed, finally the motor get stopped.<br />Once the motor has been stopped (break down), it is<br />difficult to start it again in spite of having the<br />pear full of fuel manually. Nevertheless, if we wait<br />some minutes after the failure, there is easier to<br />start again the motor.<br /><br />The refrigeration seems to be OK (there is exit of<br />water), and furthermore, the temperature of the motor<br />seems to be normal, because when the failure appears,<br />there is possible to touch the cover of the thermostat<br /> with the hand without burning.<br />A local boat mechanic has dismount and cleaned the<br />three carburetor (they were fine), and the VRO but he<br />had not found nothing wrong which could cause the<br />failure. In spite of this, he had disable the VRO,<br />disconnecting the electric system of VRO and the oil<br />inlet, and taking directly fuel mixed with 2%.<br />Doing it, the mechanic though that the problem will be<br />solved, but it the FAILURE IS STILL THE SAME<br />I realized that immediately after start the motor in<br />cool, the motor works correctly, and after 3-5<br />minutes, there is the failure. Could be possible that<br />the motor temperature has any influence? Maybe the<br />fuel pump has a failure because of wrong working of<br />impulse fuel system?<br />Anybody know what could be the cause?<br />The local boat mechanic insists that reason could be<br />of VRO system, and in his opinion it has to be<br />changed. Anybody know the price of this material and how to obtain it?<br /><br />Thanks for your reply.
