1998 200 EFI Mercury Engine
by George Hanst
My engine has been tested in the shop many times, plugs changed, and compression checked(115-130).
When I take it on the lake and place a load on the motor< I can't get more that 10 MPG with 2000 RPM when I accelerate. After about 10 minutes of stopping, starting, revving up in neutral, all of a sudden it will start gaining some speed and then it works fine. Until I stop and start again.(then same problem)- almost like it needs to get over "x" rpms to kick into normal mode. They have checked the fuel filter, fuel hose etc. Would appreciate any suggestions you might have. Thank you in advance.
