1 ABL-14d Able Elective Engines Instructors: George Crowl

2 Course Outline  d. i) Understand the safe and proper procedures for the use of gasoline and diesel inboard engines, including fueling, pre-start checks, ventilation, starting, running, periodic checks while running, securing, post-operative checks, and keeping an engine log.  d. ii) Using the type of engine aboard the vessel you most frequently use, demonstrate your understanding of basic troubleshooting and the preventive maintenance schedule recommended by the manufacturer.

3 ABL-14d i) d. i) Understand the safe and proper procedures for the use of gasoline and diesel inboard engines, including fueling, pre-start checks, ventilation, starting, running, periodic checks while running, securing, post-operative checks, and keeping an engine log.

4 Fueling Preparations  May be before pre-start, or after getting underway  All flames extinguished  Engine and electronics off  Close hatches, ports, doors  Portable tanks on dock / ground  Passengers on shore

5 Fueling  Have absorbent material on hand to mop up fuel spills  Insure you are using fuel filler, not water or other filler pipe  Maintain contact between fuel nozzle and filler pipe to prevent sparking  Listen for sound change as tank fills. Go slowly.

6 After Fueling  Clean up any spills. Dispose of absorbers.  Open ports, hatches, doors to ventilate  Do a sniff check at bilge level for fumes  Blower ventilate gas engine for four minutes

7 Starting  Use starting checklist  Open raw water valve  Listen during starting for unusual noise  Engine should settle to smooth run  Insure cooling water being pumped overboard  Log start time in engine log

8 Running  Listen to the engine. Investigate strange sounds  Check engine instruments regularly. (We know they are hard to see, do it anyway!)  Check oil pressure (usually 40-80 PSI)  Check alternator / generator (positive output)  Check temperature (under 200° F)

9 Shutting Down  Follow the checklist  Most people believe it is better to close the raw water valve about 10 seconds before shutting the engine down. This blows the water out of the manifold.  May not need to close raw water valve for short shutdowns  Log shutdown time. Log total engine time for oil changes, etc.

10 ABL-14d ii) d. ii) Using the type of engine aboard the vessel you most frequently use, demonstrate your understanding of basic troubleshooting and the preventive maintenance schedule recommended by the manufacturer.

11 Troubleshooting – Inboard  Engine won't start  Won't turn over – battery dead? Battery cables corroded? Disconnected? Starter motor relay failed? Ignition switch failure?  Turns over weakly – battery weak? Cables corroded?  Turns over fine, won't start – defective fuel pump? Fuel filter(s) clogged? Spark plugs? Diesel injectors clogged?

12 Troubleshooting – Inboard (2)  Runs, then stops – check fuel level? Boat heeling or pitching? Needs fuel?  Runs rough – electrical harness tight? Spark plugs cleaned and gapped? Carburetor dirty?  Overheating – temperature above about 190° - Faulty thermostat? Water pump failing? Water hose leaking?

13 Inboard Engine – PM  Engine oil change (interval ?)  Transmission oil change (interval?)  Fuel filter change (interval?) (how many?)  Air filter change (interval?)  Spark plugs – gas (interval?)  Diesel injectors (interval?)

14 Troubleshooting – Outboard  Starting difficulties  Fuel tank full  Primer bulb pumped hard  Gear shift in neutral  Kill switch set  Throttle positioned to start  Starter rope tight, pulled hard

15 Troubleshooting – Outboard (2)  Engine does not start – other  Old fuel (30 days +) – fill with new fuel  Kill switch engaged – disengage  Kill switch clip not inserted – insert, or remove and re-insert  Spark plugs or ignition – new plugs, check ignition system

16 Troubleshooting – Outboard (3)  Overheating  Check water coming out of motor  Check water intake clear  Check water pump impeller  Excessive vibration  Check propeller attached tightly  Check isolation mounts – tighten or replace  Propeller not turning properly  Check prop or shaft for debris  Check shear pin OK

17 Troubleshooting – Outboards (4)  Engine won't stay running  Check fuel system  Check fuel filter – clean  Check carburator – clean  Check air filter – clean  Make sure you are using the correct fuel  Gas / oil mix for 2-cycle  Straight gas for 4-cycle, check oil level

18 Outboard Engine – PM  Engine oil ratio (2-stroke)  Engine oil change interval (4-stroke)  Oil filter change (4-stroke) (interval?)  Transmission oil change (interval?)  Air filter change (interval?)  Spark plug change (gas)
