1962 Johnson 75hp

[Project-Man]

I've recently acquired a,1962 75hp johnson electromagnetic boat. I've done quite a bit getting it ready to start and hopefully float.,I've worked through most questions but have one I need help with.

These boats have lots of fuel lines and air lines and I hadno idea whom ones to hook where. I've seen several videos but can't pick out the fuel lines.

Second question. This being a 2 stroke motor the plugs should be firing every stroke. Therefore it doesn't matter where your plug wires go? Correct?

When I get the pubs together I'll post some on the work I've done.

Not an expert here, but it ABSOLUTELY matters which plug the plug wires go to...

Not familiar with your particular engine, but fuel lines would run from tank, to engine cowl connection, then to pump, then carbs.....

Sounds like you should get yourself a factory service manual at a minimum as it will describe in great detail how it works.

Electric primers came out in 1980.

That motor also has three water hoses to the automatic choke. Actually two water and one vacuum line.

Firing order is 1-2-3-4.

#1 is the highest up, #2 is next down, and on other side, #3 is next down and back to the first side, #4 is lowest and on other side again.

I assume you motor is nearly the same as mine. Here are some pics of the hose and wire routings. Let me know if you need more zoomed-in pics and ask if you have more specific questions.

Snazzy paint job....I would have thought the distributor cap would have been on the bottom, like my Fat-Fifty.

Magnetos have the cap on the bottom. Battery ignitions have the cap on top. CD ignitions are a different story.
