    1978 Mercury 700 Control Box

    I will probably do that. A lot easier than trying to figure in another box unless I get a match. Thanks again for everything.

    1978 Mercury 700 Control Box

    Gentlemen, thank you your assistance. It is deeply appreciated. I will give it a try to crank and get the compression test. Then test the wiring before I even try to start it up. I am sure some fuel lines will have to be replaced after this length of time. That diagram of the control will...

    1978 Mercury 700 Control Box

    I know the prior owner quite well. There was nothing wrong when put in storage. This is a barn find. The mistake he did was to get rid of the boat with the control still inside. I will run a compression check on it now that I know how to jump start it. Thanks for the tip about spending the money...

Seller says Mercury and the connector is very close but the pin configuration is one pin off but it appears to have the right...

    1978 Mercury 700 Control Box

    I have attached a photo of the connection on the motor and the coils. I have not tried to take the wire harness off the motor or apart yet so I can't tell what colors I have coming from it. This will have to be done sooner or later because the insulation is flaking off. I expect most of the...

    1978 Mercury 700 Control Box

    I just purchased a 1978 Mercury 700 70 hp Outboard S/N 4982717. This motor has less than 200 hours on it and has been stored since 1981. The problem is that the remote control box was left in the boat which was sold years a go. I have searched the internet and called Mercury to try and get a...
