1968 Johnson 55 HP Parts Catalog Corrections and Emergency Starter Rope - DL-172

Johnson corrected two part numbers in the preliminary 55 HP parts catalog and explained why the 1968 TR model needed a different switch for its fail-safe Hydro-Electric shift system. The letter also instructed dealers to move emergency starter rope #378347 from the owner kit into the bag attached inside the motor cover.

SUBJECT: 55 H.P. PARTS CATALOG CORRECTIONS AND

ASSEMBLY OF EMERGENCY STARTER ROPE

Your Preliminary Edition of the 55 H.P. parts catalog should be corrected as follows:

Catalog locationItemNow readsShould read
Page 15Item #21 Spark Plug, AC-V40 FFP/N 383161P/N 383181
Page 23Item #48 Switch and Cable AssemblyP/N 379526P/N 382661

With reference to the Switch and Cable #382661 as used with the 55 H.P. motor, a short explanation is in order as to why this motor requires a new and different switch.

As you know, the 55 H.P. model TR has the new Hydro-Electric drive which is spring loaded to be fail-safe in forward gear. With this in mind, no electrical current is required to maintain forward gear engagement. Therefore, the #382661 Switch does not conduct current in the forward position, but does conduct current in the neutral and reverse positions.

The #379526 Switch as used on past and present Electramatic shift engines conducts electrical current in forward and reverse positions but not in neutral.

It is imperative that this difference in switches be noted and remembered as the remainder of the Remote Control Assembly components are identical. The connector on #382661 Switch and Cable Assembly has a male housing whereas the connector on #379526 Switch and Cable Assembly has a female housing. This assembly procedure will prevent interchangeability.

The Emergency Starter Rope, #378347 will be placed in the owners kit at the factory. We request you remove the rope from the owners kit and place it in the bag which is attached to the inside of the motor cover.

The required curing time for the adhesive used to secure the bag to the motor cover prevents us from placing the rope in the bag during assembly.
