I just had lower unit replaced and now I hear a gurgling sound and I cannot tell if it’s water gurgling in the motor or a suction issue for the gas line.. Can you help? It seems to run OK, cranks easily, but only top speed at 57 mph. I understand that it should be much higher. It is on a 19 foot Stratos 2007 boat.
