When shifting from neutral to drive, E-Tec 50 has high RPM (2500) but slow boat speed unitl throttled up higher then reduces to normal RPM 800-1000, appreciate any thoughts
Sorry, but its hard to understand exactly what you are describing.
What is the engine model number?
Did this just start happening after something was done to the boat or motor or did it happen all of a sudden out of the blue?
Could you elaborate the sequence of events in more detail?
