Johnson Service Bulletin #495 (1955) - Mercury Switch Identification

It's possible to find yourself in a bit of difficulty with installation of the mercury cutout switch on the RDE series, unless noting on observation of the switch assembly that angularity of the mounting bracket attached to assembly #376323 (RDE-17) is somewhat greater than that provided #376242 (RDE-16) as noted in above illustration.

Avoid "switching" the installations, since doing so will result in one or the other of the following discrepancies (1) not permitting electric starting in high neutral position (cutting out too early), or (2) permitting a starting at excessively high speed (cutting out too late).

The respective "switches" may be further identified by methods of clamping to lead wire as illustrated here.

Please take note.
