I bought the boat last year. The first few times i took it out it did fine. Then all of a sudden it would not open up and plane out. I parked it for the winter. This spring I added a power tilt and trim, changed the plugs and wires. I checked my fuel tank out because the fuel hand wouldnt work, the tank was rusted over. I took the metal tank out and replaced it with plastic fuel tanks. The first time out after all the modifications it ran fine. I messed up and added the fuel from the old metal tank to my plastic tanks. I took it out and it ran good until i shut it down and began fishing. When i started it back up and began to run to another spot the motor would not open up and plane out. I have flushed my tanks, cleaned the filter ect. It is still giving me the same problem, it will not open up and plane out. Can you help me? I was also woundering the year of my motor, the vin is 7418. 1359 hd is above the serial. Another question, the water pump just spits a mist out could this contribute to my problem?
