Dealer Letter #110

SUBJECT: Service Parts - Johnson - OMC 4 Cycle Stern Drives.

Gentlemen:

The acceptance of the Johnson and the OMC four cycle stern drive units has exceeded all expectations. Many boat manufacturers are installing these units as original equipment and these, plus the Johnson stern drive units installed in Johnson boats will be appearing in increasing numbers on the waterways.

All good Johnson servicing dealers should prepare immediately to profit from the service and maintenance of not only the "DU" and "DUE" two cycle 88 horse-power stern drive unit, but also the "CU" and "CUE" four cycle, four cylinder 110 horsepower and the "HU" and "HUE" four cycle six cylinder Vee 150 horse power stern drive units.

The model "CU" and "CUE" uses a four cylinder Chevrolet engine with certain OMC modifications. The model "HU" and "HUE" uses the Buick Vee-six engine with certain OMC modifications. This Vee-six engine is also used by Oldsmobile, however, our supplier is Buick.

So you and your service personnel fully understand the parts purchasing procedure for these four cycle engines the following has been prepared.

To obtain parts for either the Chevrolet or Buick engines you will have two (2) sources of supply:

1. Your Johnson or OMC Parts Distributor. 2. Your local Chevrolet, Buick, Oldsmobile or United Motors Distributor.

All parts which carry an Outboard Marine part number will be shown in the Parts Book in the same manner as all OMC part numbers. ALL PARTS using a General Motors part number will be indicated with a difference style of type and will be printed on a gray background.

All parts whose numbers are printed on a gray background must be purchased through your local Chevrolet, Buick, Oldsmobile or United Motors Parts Distributor.

All parts which carry an OMC part number will be available through your Johnson or OMC Parts Distributor.

We suggest that you contact at once your local Chevrolet, Buick, Oldsmobile or United Motors Service dealer and make arrangements for the purchase of such parts as you may need when servicing these units. These dealers should extend to you a trade discount on the parts purchased. This discount will vary from 20% to 40% depending on the part and the dealer, however, it is not mandatory that they give it to you. When you contact your local Chevrolet, Buick, Oldsmobile or United Motors Parts Distributor, use your stationery or business card to identify yourself as an authorized Johnson dealer.

We have been advised that the local Chevrolet, Buick, Oldsmobile or United Motors service dealers will cooperate with the Johnson dealer organization in supplying the necessary parts at the trade discount. Should you experience any difficulty in obtaining Chevrolet, Buick or Oldsmobile parts in your area, please let us know and we will investigate the matter.

The matter of warranty on the Chevrolet or Buick engines will be covered separately in a separate letter.

Now is the time to make your contacts to obtain parts for the two four cycle engines. See your Chevrolet dealer for parts for the CU and CUE 110 horse power engine. See your Buick (or Oldsmobile) dealer for parts for the HU and HUE 150 horse power engine. A list of commonly used G.M. parts is attached for your guidance. To avoid confusion and problems during your busy season make your personal contact now.

Cordially,

JOHNSON MOTORS
