    MERCURY CONTROL BOXES

    I think the saying goes I'd rather be lucky than good?

    MERCURY CONTROL BOXES

    Attached is the diagram I used to figure it out, both are Mercury quicksilver controls, I circled the wires and then the kill wire

    MERCURY CONTROL BOXES

    I have to thank everyone for their help on this, I had some time to work on it last night and got everything working, Chris I believe you are correct in saying if it plugs in it will probably work. I ended up going over a few wiring diagrams to realize the wires even though different colors were...

    MERCURY CONTROL BOXES

    It looks like by the wiring diagrams the kill wire and the choke wires are backwards on the two plugs, I'm going to check visually in the next day or two.

    MERCURY CONTROL BOXES

    Thank you Chris the control box I am trying to use has the bullet connectors already there for the tilt/trim and I took the jumper off the 70 hp to make the bullets work, Main concern now is the wiring on the 8 pin possibly not lining up.

    That is awesome! Looks like it all matches up however digging a little deeper I found these diagrams, two wires are showing to be in different locations than the diagram you have posted there

    MERCURY CONTROL BOXES

    Both harnesses have not been modified, I have a little more information after working on it a bit last night. This is a link to the remote in the boat now I am trying to use which came from the 70hp that was on there previous...

    MERCURY CONTROL BOXES

    I am putting a new to me 90hp 3 cyl two stroke on a boat that currently has the same era late 80's early 90's 70hp 3 cyl on it now. I would like to swap the engines but not the control boxes as the wiring runs through the boat. The harness in the boat has the same 8 pin connector however the...

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    Just to be clear, your saying leave it at the 28 for factory spec not the 33 i found it at correct?

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    Another question on timing this engine, manual states to set the max timing @ 28 degrees BTDC while cranking, the motor was set @ 33 degrees when I checked last night, I moved it back to the proper 28 but I have heard of people retarding the timing a touch to compensate for the possibility of...

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    Thank you to everyone that replied, I had some time to work on the motor last night and problem solved, it ended up being a bad fuel pump flooding the cylinder, I didn't think it was going to be that as it did not respond to pumping the primer at all. I decided to rebuild it because it was cheap...

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    Almost a 100% guarantee the engine was sold because it does not run correctly, but it has good compression so I believe it can be repaired, do you suggest I just give up and buy something else? If you would kindly read what I have already posted you would see the oil injection system has been...

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    Float level was set per the manual but without it in front of me if I remember correctly it is just a hair above level with the bowl turned over, I used oem carb kits which I got from a well established online retailer, everything matched up nicely, I have also tried using the old needles to no...

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    What simple trouble shooting should be preformed? I am having an issue on one cylinder best I can tell, it didn't make sense that it would be a sheared key to me that is why I asked the question if it could effect only one cylinder. Why would you suggest that? I am asking questions to find out...

    Mercury 90HP 2 stroke 0B153965 won't idle - poor running

    Would a sheared key be throwing the timing out on just one cylinder? I did look at the reed valves when the carbs were off and they looked ok but who knows for sure.
