HERE ARE SOME BAD EXAMPLES
(Click on the images for full-size)
If you want
to see what can happen to that nice shiny outboard motor you just
purchased for a small fortune, read on. These are just a few examples
of what can happen in just a short time without proper care and
feeding. Click on the pic to see the full size image. Use your browser's"Back"

This is an example of
the corrosion that can ravage any outboard built by any manufacturer
in just a few short
years of exposure to salt water and tropical
conditions. This motor is a 1994. |
Another view of the same
powerhead. Corrosion around the head gasket and coil ground.
An occasional rinse with
fresh water and an application of
OMC 6 in 1 or your manufacturers' equivalent will alleviate
this. |

This gearcase has been
painted with some white finish, applied with a brush. In
the process the
zinc anode(on this model attached to the anti-ventilation
plate toward the front) was covered with paint,
rendering it
useless for corrosion retardation. As a result, you can see
the paint peeling away and
corrosion towards the aft end of
the plate where a trolling fin was attached. |
| Terminated. You MUST USE
good oil in your motor. This con rod failure was caused by
lack of proper lubrication. The roller
bearings literally melted;
the rod became so hot the cap bolt failed and the cap came
off. You can see some of the thin
sheets of metal that were rollers
in the foreground. |

 |
Damaged reed assembly from the engine
with connecting rod failure. This motor was damaged beyond
repair. |
| This piston has an excessive
buildup of carbon on the skirt. The lower ring is stuck in
the land, the upper one will soon be pushed out of the groove
and catch on the port, causing a ring failure. The rings
are the medium by which heat is transferred from the piston
to the cylinders, and with rings stuck, the problem is exacerbated
by the heat. This piston came from a motor with less than
300 running hours. On older crossflow models it is IMPERATIVE
you use TCWIII oil, PREMIUM gas, use motor manufacturers
carbon guard additive and apply engine tuner seasonally.
These problems are caused by the lowering of octane, removal
of lubricating lead and detergents from the fuel, not by
engine design. |
 |
These
are just a few examples of what can happen to your equipment without
proper care. A lot different than your car that cruises lazily down
the freeway at 2500RPM. BE aware and diligently care for your outfit,
it will return the favor with many years of trouble-free service. |
