    I had no problems taking the impeller off a 135 hp it seemed like it was buttered up but this impeller on my 85hp seems like it is glued. Can't seem to dislodge it from the shaft. Anyone have any tricks? I'm not sure I want to pry up on it from under with a flat head, don't want to cause...

    73 Evinrude 85hp Stator dva output

    Running through the electrical troubleshooting and found that when I disconnect the kill wire the motor would start. Took it down to the lake to try it out and it all of a sudden would no longer run or start. Seems like no spark again! I checked the two brown wires for the output from the...

    73 Evinrude 85hp bad kill wire

    I disconnected the black yellow wire at the power pack and the motor final runs. Sounds good too have yet to water test it but I don't forsee to many issues as I have good compression all around at 120 psi. My question is is there an easy fix for this kill switch wire or how do I go about...

    73 Evinrude 135 4cyl Power loss

    73 Evinrude 135 4cyl Power loss..... I recently obtained the boat and motor and changed prop due to a spun hub. When the boat is in the water it idles fine and seems to operate at low speeds fine. When throttled down the boat will gradually increase speed but nothing spectacular just plows...
