"I have a 2003 40 HP 4 Stroke that sputters, dies back in RPM when it throttle up to 1800 RPM or so and keeps doing it till around 2500 RPM. Idles great, runs wide open great but just cruisng at these RPM's it tries to stall. New water seperator, new gas, carbs rebuilt just before I bought the Whaler in June. Fuel lines look good and sealed. Seems to run smooth through the problem RPM's when I flush it on the trailer not under load.
