• Replace fuel filters
• Other Systems same as previously covered
• with Gasoline Engines

13
Diesel Engines(Spring Service)

• Fuel System
• Replace filters (if not done at winter Storage)

• Remove cover
• Clean
• Other Systems same as previously covered
• with Gasoline Engines

14
Outboard Engines(Winter Storage)

• Add fuel conditioner to fuel tank
• Run engine for several minutes
• Disconnect fuel line and inject fogging oil
  directly into the carburetor throat
• Remove engine from water and while upright slowly
  crank several times by hand
• Drains water from the water pump

15
Outboard Winter Storage 2

• Remove sparkplug and spray rust-preventive oil
  into each cylinder
• Clean, check and gap or replace sparkplugs
• Touch-up paint where paint missing
• Spray metal surfaces with moister inhibitor
• If applicable, service battery
• Drain fuel from tank and store tank outside
• Store in an upright position
• Service Lower unit per next section

16
Outboard Engines (Spring Service)

• Inspect, clean and gap or replace spark plugs
• Inspect, clean and replace, if required, wires
• Replace fuel filter (unless replaced at winter
  storage)
• Reattach engine to boat
• Fill gas tank
• Correct fuel-oil mixture
• If applicable service and connect battery
• Service Lower unit per next section

17
Lower Units(outboard and I/O)

• Winter Storage
• Lubrication System
• Drain small amount of gear oil
• Top-off gear oil
• Lubricate pivot pins and gimbal bearings
• Propellers
• Remove propeller
• Apply waterproof sealer to splines
• Replace propeller

18
Lower Units - 2

• Winter Storage (cond)

26
Tiller

• Simplest and most sensitive

27
Drum-and-Cable

• System using sheaves and pulleys
• Require regular inspection and adjustment
• Relatively easy to maintain

Outboard
Sailboat
28

29
Pull-Pull Cables

• Always under tension
• Positive steering control

Gear-and-Sector

• Direct drive system
• Quadrant gear attached directly to rudder post

33
Rod-Type

• One of the oldest and simplest

36
Hydraulic Steering

• Components
• Wheel, hydraulic pump and steering cylinder
• Reinforce nylon hose or copper tubing
• Require fixed stops to limit rudder travel
