I have a 1989 130 Yamaha on the back of my norriscraft just got it on tuesday. Took it out right after i bought the boat and when i would go to take off the motor would cut off, then after i would get it goin and went up the river and go to slow down and stop it would shut off as well. Also when i went to put it on the trailer and gave it gas the motor shut off as well. This boat has been sitting at the dealer since the end of last summer and i am sure it hasnt been ran. What should i do to fix these problems or what might be wrong?
