Session T-10: Outboard engine trouble shooting

Time 7:30 AM


· For trainees to become oriented to trouble-shooting techniques necessary in outboard engine maintenance, repair and operation

· For trainees to do actual maintenance work

· For trainees to be checked out in small boat handling skills


During this session trainees learn about outboard engine troubleshooting. They will learn how to do simple maintenance tasks and the importance of doing these tasks regularly. During this session each trainee will go out in a small boat with technical trainer to be "checked out" in their ability to handle a small boat.

Materials and Equipment:

· Outboard engine, new parts, spark plugs, starter cord, fuel filter, transmission oil, propeller, grease gun, WD 40/Solvent, OB engine tool kit Procedures



2 Hours

1. Technical trainer asks for trainees to volunteer to do one of the following maintenance functions on the demo outboard engine Ignition systems

- remove spark plugs, clean and/or replace

- use spark plug wrench correctly

Starter Cord

- remove starter cord housing

- remove starter cord

- replace with new starter cord

- check main spring for cracks

- lubricate and replace starter cord housing


- adjust idle valve/screw (for rich and/or lean fuel mix, one quarter turn for each


Fuel Filter and Transmission Oil

- remove filter and clean with gasoline, replace filter

- transmission oil/drain old oil, replace lower unit housing transmission oil

Engine Housing Maintenance

- clean upper and lower unit with fresh water. Wipe salt water from unit with clean rag after use

- clean inside of upper unit with clean cloth soaked in solvent and/or WD 40.

- flush water cooling intake with fresh water, to clean out collected salts and prevent marine corrosion


- remove and or replace propeller, locate nicks and/ or cracks in propeller and file down

- remove propeller and replace shear pins Grease

- properly grease all bearings and/or grease valves Corrosion

- locate pitting and/or corroded surfaces, clean, file down do bare metal, repaint with anti-fouling compound paint. Use only approved paints for aluminum surfaces.

2. Technical trainer announces that all trainees will have to be able to perform all of these maintenance functions within a week. They are free to practice on demo, but will be expected to do a complete maintenance check on one of the local fishermen's outboard engines.

Trainer's Notes:

Trainee will have to make own arrangements to do free maintenance on fishermen's O.B. engines. It is advisable to have one of the trainees who understands O.B. functions to check out those who are doing maintenance for first time. Every trainee must be able to perform all functions. It is important for you to emphasize that O.B. engines will last a long time with proper maintenance, and that one of the biggest problems found in developing countries is that maintenance functions are not demonstrated thoroughly to fishermen. Consequently, there are many unnecessary costly repairs incurred by the small-scale fisherman.

20 Minutes/ trainer

3. While trainees continue to practice maintenance trainee functions technical checks out trainees in small boat handling.

Trainer's Notes:

For some of the trainees this will be the first time handling a small boat. Technical trainer will give these trainees initial instruction and allow them to operate the boat in open water. Trainees will have to find practice time, and until they check out will have to go out in boat with one of the trainees who can operate a boat safely and correctly. Once again trainees have only one week in which to acquire this skill and be checked out. When they feel they are ready, it is up to them to ask to be checked out.

1. Trainee check out list:
- Overview of check-out
- Starting
- Reverse
- Low speed (no wake zone)
- High speed
- Wide circle
- Tight small circle
- Bay entrance
- Stop engine
- Start engine
- Return to dock
- Low speed (no wake zone)
- Docking
- Night navigation/operation
