    Greetings.

    I will be picking this engine up in New Hampshire in a few months but in the meantime here are a few pics. The serial number looks pretty bad. Is there another place on the engine I can have someone look? Or does anybody have a good guess?

    Thanks

    Ralph

    maybe a 1937 Johnson 4.2 HP Outboard Motor
    the model number and serial number will tell the truth
    if you can post it better
    good luck

    I will try to get another pic but fear that the model and S/N are pretty corroded. If they are how do I go about ID ? Is there something on magneto? or other engine parts that will help solve the puzzle?

    Decal is 1937. Serial number should be on the block as well.

    excellent thanks Wayne. Do you know if I can find any documentation for it in that Big Red book thing? Is the link working?

    The serial number is legible. It is 257089 Can also read LT37. Is it possible to get a schematic of this? I have no spark and will be removing flywheel soon to look at things.

    Thanks

    That 4.2hp motor was made two years – 1937 and 1938. Should turn out as a good running motor.
    Carefullly clean the points, replace the leathers in the primer, clean the inside of the tank and pump in
    lower unit and it should be ready to go!

    thanks Itchy,

    It had spark. After cleaning and reinstalling the carb I had it running briefly from a hose fed fuel funnel. Did not get enough time to adjust fuel mix. Can you please tell me what the initial settings should be on the needle(s). Also should there be an open hole on the part where the primer goes? Any other operational stuff appreciated.
    Thanks Ralph

    Initial settings for both the high and low speed needles should be 3/4 turn open from lightly seated closed. Don’t know what you mean by “open hole on the part where the primer goes” Compression should be 70-77psi. Much good info at: pochefamily.org/outboard except the ad for leather primer seals is about 15 years old and I had to update the price for seals to $10.00 a few years ago. Hard to get the proper leather to make any more.

    here is a pic. Am I missing something? When I press the primer I do see fuel coming from the hole in the “Y”
