I picked up a 1991 four stroke Yamaha 9.9 long shaft to hang on the back of the sailboat this year after I get an old screw jack adjustable motor mount on the transom. (This thing is heavy) The model of the motor is T9.9EXHP
The motor turns over but has no spark. I am a fluid, spark plug...
I am looking to purchase a 1986 Sea Ray with the Mercruiser package that includes the 5.7 L V8 engine.
The owner started having trouble with the engine as he was getting ready to sell it. He has been very forth coming and I believe that this is the complete information.
The unit had problems...
