SUBJECT: 1965 Outboard Optional Propeller Program - 18 Thru 90 HP.

Gentlemen:

The propeller option program, introduced in 1960, remains in effect for 1965. It is offered to provide every dealer with the privilege of custom matching propeller, boat and motor at the time of sale.

Under the propeller option program, the purchaser of a 18 to 90 HP motor is entitled to any one of the propellers listed on the enclosed sheet, in exchange for the propeller supplied as original equipment on the engine. Naturally, the propeller the customer will require is dictated by the characteristics and requirements of his specific boat, motor and load combination. With few exceptions, the majority of customers are unaware of the conditions governing propeller selection, and are completely dependent upon the dealer to determine and select the propeller for him. This program will only be as effective as you make it. We therefore urge that every dealer follow through and make these options known to the customer and explain why.

For convenience in handling the propeller options, the following procedure has been set up:

Each motor shipped from the factory - 18 to 90 HP - will be equipped with a propeller. If the dealer determines this propeller is not the one the customer will require, he should supply any one of the remaining options from his stock and install it on the engine.

At any time a dealer finds his propeller stock has become unbalanced, that is, more of any one kind than he wishes to carry in stock, he has the privilege of returning them to the parts distributor for exchange, and receive propellers of other sizes for the same horsepower engine.

We suggest that propeller cartons be saved for repacking of propellers returned to the parts distributor. To facilitate handling, please accumulate these propellers and make only one shipment every thirty days, transportation charges prepaid. Please note these propellers are to be returned to the Parts Distributor and not to the factory. Under this program, the parts distributor is entitled to the same return privileges, but he will deal directly with the factory.

From the foregoing, it should be obvious to the dealer, that there are three extremely important obligations to meet.

1. Maintain an inventory of all the propellers available for the motors covered by this program, plus a stock for lower HP engines.

2. Determine which propeller will permit the engine to develop its full potential on the basis of the customer's specific boat and load requirements.

Your experience with various size boats and loads, and the use of a good portable tachometer, will eventually enable you to pretty well judge with the aid of propeller selection charts, which propeller will be required. Engine RPM should be 4700 to 4800 when running light. Under no running condition should engine RPM be less than 4400 at full throttle.

Engineering tests have revealed that in propellering the 90 HP for peak water skiing performance, a slight deviation from the preceding RPM recommendations is required. It is recommended that a propeller designed specifically for this type of water sport be used. In most applications, the Johnson 10 x 9-1/4 propeller (P/N 379260) will do an excellent job. The use of this propeller on some boats may mean the engine RPM will exceed the recommended 5000 maximum. This is not harmful to the engine if the following two simple rules are followed: 1) Maximum RPM’s should not exceed 5500, and 2) the throttle should be retarded to 5000 RPM when the boat is being operated without skiers.

Complete details concerning the application of the Johnson SKI-GO Propeller (10 x 9-1/4 - P/N 379260) are covered in Johnson Service Bulletin #SB-1038.

3. Make monthly returns of new and unused propellers to your parts distributor, transportation charges prepaid. Propellers that have the appearance of being used or damaged, will not be accepted.

The primary purpose of this program, is to minimize the possibility of low RPM operation at full throttle. The correct propeller, in addition to providing improved performance, will also result in better economy, smoother operation, better acceleration and protect the engine from premature failure. The end result is obvious - A SATISFIED CUSTOMER!

REMEMBER - A SATISFIED CUSTOMER IS ONE OF YOUR BEST FORMS OF ADVERTISING!
