ABL-14 d Able Elective Engines Instructors: George Crowl

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, postoperative 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.

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

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.

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

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

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)

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.

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

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?

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? )

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

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

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 �

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

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)
