Johnson Service Bulletin SB-671 - Gaskets

We are always very much concerned about our Consumers getting the best product we can make as well as the best service and Service parts obtainable.

We understand that someone recently has offered our Dealer organization a full line of gaskets that allegedly fit all models of our motors.

We would like to call your attention to a few facts concerning the gaskets which we supply as service parts.

1. Much engineering time is spent on the selection of materials that go into our gaskets, thickness and exact sizing of the holes, etc. Many of the materials used by us are to avoid electrolysis of the metal on each side of the gasket. These specifications cannot be seen by visual examination.
2. We have packaged our gaskets in sealed packages, based on our experience and requests from Dealers so correct moisture balance can be maintained and gaskets will not curl and will not shrink so correct size will be held almost indefinitely.
3. Gaskets hanging in the open will dry and shrink to the point of being useless in a short period of time, costing money when you tear or scrap them.

We feel that our customers are entitled to the best possible, and that you will serve our and the customer's best interest by supplying GENUINE GASKETS AS FURNISHED BY THE MOTOR MANUFACTURER.
