    Default Johnson 70hp Start Problem

    Hi, i have a 1986 (i believe) Johnson 70 HP. I was running my boat last season fine, A week before i went to winterize the engine, i went to put my boat into the water and turned the the key and the engine would sound as if it was about to start then would cut out. I have a 1986 Starcraft center console. The engine has gotten its Carbs changed two years ago I was wondering what type of issue i could be having.

    example:
    place my boat int he water. i turn my key, sounds like it is going to start up but never reaches like full power then slowly fades off.

    Any help would be great, maybe just an idea of what is wrong and maybe what i could do to fix this and cost.

    Go to the Engine FAQs Forum. Do the troubleshooting in "Outboard won't start".

    Let us know what you find.

    And, oh: Welcome to iboats.
