      The four is one at the tank,a blue one on the motor, high pressure, and one in the vst, it run better but still not as strong as the other side. It will run out at 6150. The port side will only run at 5600 rpm. And you can tell that it is weaker than the other. Pulling more rpm????? I bought the boat from somebody and he told me that it has set up for a year.
