    We picked up a couple Sea King’s this weekend and I’m trying to figure out when they were produced. The serial and model number guides I have don’t show either number.

    The first appears to be based on the 1931-33 Evinrude Lightwin 4 hp. It is model number 8837. Model 88xx was used from 1935-39 as best as I can tell. It’s possible this one was built from parts . During this time.

    The second appears to be based on the 1934 Evinrude Lightwin 5.1 hp. It is Model number 4940008. That doesn’t match any known model number.

    Your second motor appears to be a 494 ’34 four horse twin with a really low serial number. Eighth one off the line? I’m not sure about the first one yet.

    Did you check for a brass welch plug behind the carb? The Sea Kings I’ve seen usually have one located there somewhere with all the numbers stamped on it.

    I’m reading the model guide wrong. The two model guides I have show 494 8803 as 1936. I guess the other will remain a mystery. The welch plugs have no identifying marks. 88xx doesn’t show up until 1935 and 8837 never makes an appearance.

    Nice example.
    Someone spent some time on it.

    The previous owner did a nice job on the restoration. Unfortunately, it won’t run on fuel through the carb. So that is the next step.

    The second Sea King is a nice original. It belongs to a friend.

    “Unfortunately, it won’t run on fuel through the carb.”
    Pretty simple carb. Fuel goes from the float bowl to
    a hole in the seat under the poppet valve. The mixture
    screw is in between controlling the amount of fuel.

    Just like an ELTO carb with that big poppet valve. I haven’t spent much time on it. It fired on penetrating oil on the first pull, but nothing through the carb. I gave it 15 minutes and moved on. I had two other motors to test and limited time. I’ll get back at it soon. 😀

    Success! Had it running tonight. Once I figured out where to set the carb needle it would start and run well. YouTube isn’t working for me right now or I’d post a video.

    I have a couple 1929″s with the Atwater-Kent ignition
    and the folding lower unit. They do a pretty good job
    of moving a boat for a small motor. Yours might be
    a bit quicker with the magneto.

    Thanks guys. Tubs, your folding Lightweight is fantastic. I almost bought a pair of them at Constantine this past weekend.
