* It's easy to keep your outboard in tip-top shape, even if
you're not a mechanic. A little TLC and preventive boat motor maintenance
facilitates safe boating and can keep your motor running well and reliable for
years to come.
After Every Trip
- After every outing, flush out the engine. This doesn't
just apply to salt water adventures, but to fresh water outings as well.
- Buy a set of "rabbit ears": two flexible
rubber seals connected with a metal clamp. Slip the apparatus onto the
lower unit where the water is picked up and attach a garden hose.
- Start up the engine and let the water pump do the rest.
(Practice safe boating and remember to stay clear of the prop and make
sure no one tries to shift the motor into gear.)
- While you're flushing the motor, check the water pump
to make sure it has good water flow. Carefully put your finger through the
stream of water. It may be warm, but it shouldn't be hot. If the output is
not strong, you may have some debris stuck in the outflow tube.
Immediately shut down the engine to prevent overheating and damage.
- Insert a small piece of wire into the flow tube and
work it back and forth. Start the engine again and check the output. If
that doesn't solve the problem, you may need a new water pump.
- After flushing the engine, disconnect the fuel line and
allow the engine to burn all the fuel in the carburetor.
- Once you've finished the flushing and run the engine
out of fuel, be sure to turn off the key and, if you have a battery
switch, turn it off.
- Take the engine cowling off and check for fuel or water
leaks. If you find leaks, consult your safe boating mechanic.
- Wipe everything down and spray with an anti-corrosive
like WD 40 or Quick-lube. Be sure to lubricate all the moving parts such
as the shift and throttle cables, carburetor valves, etc.
- Replace the cowling and wipe it down. Keep a canvas or
plastic cover on the engine between trips.
- Always use fresh fuel. At the end of the season, boat
motor maintenance should include draining your tanks and taking the fuel
to the proper recycling authority.
Regular Maintenance
- Periodically check the fuel line for cracks and worn
spots.
- Make sure the fuel primer bulb is not cracked and is
pliable.
- Make sure the fuel-line fittings seat properly and
don't leak.
- Check the clamps on the fuel line for rust or corrosion.
- Check the fuel tanks for damage and corrosion.
- Check the tank vent to make sure it aspirates properly.
- Check regularly for water in the fuel.
