I recently purchased a 1995 Lund Pro V 1775 Tournament Series boat with a Yamaha 115 V4 motor and stainless prop. The motor starts, idles and runs great, but I noticed when I first give it a little gas it runs rough and shakes more than it should. As I give it more gas, it cleans up and runs smoothe. The motor also has a noticable ticking noise all the time, not loud but still there. I took it to an authorized repair center and they told me there is nothing wrong, and the problems I stated are common with the motor. I don't agree with them and am now asking for your help. Any suggestions?<br />Thanks,<br />Rob
