I have a 1998 Johnson 70 HP (4 cylinder, 4 stroke) Outboard that is experiencing symptoms that sounmd like Slow Mode. I have not yet had it on the water. Previous owner, is a person I can trust and claims that the motor ran perfectly 2 years ago. I changed gasoline and added Sea Form. The motor starts up great and runs well untill I hit approximately 2500 RPM. There are no Red Lights lit when this happens and I know that all lights work because they cycle on and then off during initial Key on. All of my testing has all been done with the Ear Muffs on. Water Pump seems fine - there is a steady stream of very warm water pissing out the indication hole.
