I just got a 1983 15hp Evinrude. The owner had not started it in over 5 years. He tells me the only thing ever done to the motor was a carb. re-jetting. It has never seen freash water. Questions: The gas has been drained, the cover has been removed to see if everything is there. No corrsion on parts under the cover or on the outside of the motor. 1. Can anyone please tell me were to start with this motor? Should I mix up some gas 40:1 and try to start it? I have a new Water Pump kit for it. Not yet installed. Waiting for a manual to come in. When should I replace this part? Are carbs. on this type of motor similar to dirt bike carbs? Since the motor has never been in freash water only salt, should I be concerned? 2. The starter gear/flywheel gear seem to be worn (theeth). Can I use this or do I need to replace them? They are not real bad, but you can see where they are worn on one end. Any advice would be Greatly Appreciated.
