If I cut it back to idle as soon as it starts to stall, I can save it and then get back on plane. If I leave it at mid throttle it will cut off and the primer bulb will be empty but not flat. To get it to start again all I have to do is squeeze the primer bulb and it fires right up. I can then run at WOT all day long. Actually I can run at rpm plus with no problems. Below is a list of things I have recently replaced as I bought this boat used earlier in the year.

Oil and filter change In boat fuel filter change Low pressure fuel filter change New spark plugs New Tank vent cover near fuel filler as the old one was busted off Things I am considering as a possible fix Ensure vent line is clear from the tank to the vent Replace primer bulb Drain gas and replace with new Remove anti siphon valve on tank The odd thing about this is it appears to be a fuel starvation issue but it doesn't happen at wot.

At first I thought I was out of gas but that was not the case. I also thought that due to the increased angle of the boat due to just being on plane that the fuel pickup may be struggling to pick up fuel but once again I had 30 gallons of fresh gas in the tank with marine ethanol treatment.

Any thoughts? Forum Founder. I'm dealing with something similar with my DF I did everything you did to try to diagnose the problem and I also changed the plugs and tried running on a remote tank, still the same issue. A common issue with this outboard is the filter in the VST tank - it will become partially clogged and can sometimes show up as the symptoms you're describing.

In order to change this filter, the manual calls for you to remove the intake manifold so you can remove the VST tank, which is a bit of an involved process. One thing I've also tried is disconnecting the line that runs from the High Pressure Fuel Filter to the fuel cooler, and then I hit the key and caught the fuel in a clear container so I could check the quality of the fuel coming from the filter mine was good.Evinrude E-TEC sets the performance standard for outboard engines.

The story begins in the mid s when the EPA decided it was time that outboard motor companies start to clean up the exhaust emissions of their motors. At the time Evinrude and Mercury were the only major manufacturers of two stroke engines. The time frame the EPA gave was going to be a challenge to both companies. Mercury decided to partner with Yamaha, they were already building some smaller models for Merc.

Incorrect reporting by some national boating and fishing magazines added fuel to the incorrect perception. Outboard Marine Corp. In mid March Bombardier Corp. Swiftly BRP started making huge changes in the structure of the outboard builder. From a dealer standpoint the engine was instantly the best technology we had ever seen. A computer controlled fuel injection system that delivered amazing fuel efficiency, instant throttle response, smooth quiet performance, and unparalleled hydrocarbon emissions.

As Japanese engine builders continued their strategy to reinforce that they were making the smoothest, quietest, cleanest, and most fuel-efficient engines available.

Evinrude was actually doing it rather than talking about it. Fact: Not all four-stroke engines are fuel-efficient. Only fuel injected engines are. Carbureted four-cycle motors are NOT any more efficient than carbureted two strokes.

Fact: Four cycle engines are not the cleanest motors available. Fact: Based on independent research by leading consumer groups there is virtually no difference in full throttle sound decibel measurements of ANY engine. Usually it was a simple code to identify the year of the motor. Recently some companies, notably Mercury and Yamaha have stopped using that system. That means they can build as many engines as they want at a particular time without the fear of over-building and having surplus inventory.Make Johnson.
