I purchased a used Yamaha 4hp 2 Stroke motor. I do not have the exact year but it is approximately 10 years old. It runs great out of the water. Starts right up and runs fine in a big barrel of water. It is used on a 12 foot small aluminum boat. I took the motor out on the water. It started right up but when I apply throttle it stalls right away. I started it up again and the same thing happened. I could not start it again during that outing. I had to paddle home. My arms still hurt I had nothing in the boat except for myself and I cant imagine the motor being underpowered. Do I need to let it warm for a long period of time? What could be the issue? Damn Craigslist... Any help would greatly be appreciated.
Thank you for the help,
Andy
