STARTER

MOTOR

DESCRIPTION

The

starter can be roughly divided into the following sections:

• A motor section which generates a drive power.

• An overrunning clutch section which transmits an arma-

ture torque, preventing motor overrun after starting.

• A switch section (solenoid) which is operated when actuating the overrunning clutch through a lever and which supplies load current to the motor.

The starter is a new type, small, light-weight and is called a

high-speed internal-reduction starter. The pinion shaft is arate from the motor shaft; the pinion slides only on the pinion shaft. A reduction gear is installed between the motor shaft and a pinion shaft. The pinion sliding part exposed outside the starter so that the pinion may slide smoothly without becoming fouled with dust and grease. The

USE

OF

ELECTRIC

The power required to start an electric motor is considerably more than is required to keep it running after it is started. Some motors require much more current to start them than others. Split-phase (AC) motors require more current to start, under similar circumstances, than other types. They are commonly used machines, started, such as small power tools. Because they require 5 to 7 times as much current to start as to run, their use should be avoided, whenever possible,

ven by a small generator. Capacitor and repulsion-induction motors require from 2 to 4 times as much current to start as to run. The current required to start any motor varies with the

load connected to it.

DESCRIPTION

This generator is a four-pole, brushless, self-excited

generator which requires only the driving force to produce AC output. The copper and laminated iron in the exciter stator are responsible for the self-exciting feature this generator. The magnetic field produced causes an AC voltage to be induced into the related excitor rotor windings during rotation. Diodes located in the exciter rotor rectify this voltage to

field. This creates an electromagnetic field which rotates through the windings voltage which is supplied to a load. An AC voltage is produced in the auxiliary windings is, in tum, supplied to a voltage regulator. The regulator produces a DC voltage to further excite the exciter stator windings, enabling the generator to produce a rated AC output. The voltage regulator senses AC voltage output and adjusts DC excitation to the exciter stator winding according to amperage load the generator is furnishing. constant voltage output.

LAY-UP & RECOMMISSIONING

GENERAL

Many owners rely on their boatyards to prepare their craft, including engines and generators, for lay-up during the off-season to accomplish lay-up preparation themselves.

The procedures which follow will allow you to perform your own lay-up and recommissioning, check list

These procedures should afford your engine protection during a lay-up and also help familiarize you with the maintenance needs

If

you have any questions regarding lay-up procedures, call your local servicing dealer; he will be more than willing to provide assistance.

Propeller

The transmission and propeller half couplings should always be opened up and the bolts removed when the boat is hauled out storage in the cradle.

Should more antifreeze be needed, amount from the engine block and add a more concentrated mixture. Operate the engine to ensure a complete circulation and mixture cooling system. Now recheck the antifreeze solution's strength.

Start the engine and allow the raw water pump to draw the

fresh water through the system. When the bucket is empty,

stop the engine and refill the bucket with an antifreeze solution slightly stronger than needed for winter freeze

protection in your area.

Start the engine and allow through the raw water system. Once the bucket is empty, stop the engine. This antifreeze mixture should protect the raw water circuit from freezing during the winter lay-up, as well as providing corrosion protection.

Remove the impeller from your raw water pump (some antifreeze mixture will accompany it, so catch it in a bucket). Examine the impeller. Acquire a replacement, a cover gasket. until recommissioning, but replace the cover and gasket.
