      The project is going back together, and if it actually runs and is deemed
      viable to put to water, then I’ll need to address the hood.
      The electric start parts motor was made whole via other motors, and
      I never had the electric start model’s hood.
      Is the only difference in the electric start and non-electric hoods for 57
      the decals?

      The motor came with a non original 6 volt starter motor, and I’m assuming
      it’s mounted on the 6 volt starter bracket, as it has the brass, forward pointing
      hood mount of some kind, which I don’t see on the 1957 parts diagram.
      I adapted the starter bracket by drilling and tapping
      a hole for the rubber cushioned hood side mount.
      I test fit the non-electric hood prior to refurbishment of the motor,
      using the adapted side mount, and it seemed like it would work okay.

      Looks like I’ll need to come up with four different colors of paint for said hood.
      I’ve seen some pretty nice looking painted hoods on your projects.
      I’m curious on your procedures in doing so, being there’s four different
      colors to contend with.
      After priming, do you paint the whole hood the polychromatic blue, then
      tape off and add the different colors? Or ??????

      Thanks!

        Hi,

        The forward pointing pins are for the Johnson hoods.

          I’m curious
          Why use a Johnson Starter bracket?
          I’m assuming it was from a 55 or 56
          Please correct if I am wrong but-
          How about using a rds bracket and make it 12 volts????

            Looks like those hoods are from manual start motors. The electric start had the evinrude script in the dark gray painted area and an “electric starting” script in the white painted area toward the rear. The front of the hood said “BigTwin Electric 35” instead of “Evinrude BigTwin 35”. I would paint the entire hood polychromatic blue, let it cure well, then paint the “bulged out” area on the sides with the white, then mask and add the gray to the appropriate areas.

              I learned something new today. Thanks!

                That’s the bracket and starter that came on motor, and starter motor appears
                to be in like new condition on the inside, so I thought I’d use it. I plan to use
                a 12 volt battery regardless.

                  Yes, both hoods from manual start motors.
                  Your paint method sounds “sound” to me!
                  If it runs, I will proceed with the hood. I need to
                  get the paint and some “fine line” tape.
                  Thanks!

                    A 12 volt battery should work good with a 6 volt starter. The starter current does not double like a resistive load would due to the complex inductance of the motor spinning. Just don’t crank forever if it’s not starting. It is very common practice on old 6 volt cars to use the same starter on 12 volts, and that is working out fine on my ’51 Buick that I converted to 12 volts. All you have to change is the starter solenoid and either change the choke actuator solenoid to a 12 volt one, or put a resistor in series with it of equal resistance to that of the 6 volt choke solenoid coil. Minimum power rating (watts) of the choke solenoid’s added resistor is critical. The power rating needed for the resistor must be greater than “6 volts squared divided by resistance”, or 36/R. I measured that resistance years ago, but don’t remember what it was.

                      Dave, I just made up a junction box for my boat and 1955 RDE-17 that has a 6v starter,
                      using a 12 volt battery to crank it over, and a 1.6 ohm resistor for the choke coil.
                      The choke coil sounds like it’s activating okay, but have not taken the hood off
                      yet to observe.
