Tohatsu
Outboard Motor Break-In Periods
The
following charts show the standard "break-in"
periods for Tohatsu Outboards (2-stroke, 4-stroke and
TLDI).
2-Stroke Outboards
| 4-Stroke Outboards
| TLDI (Direct Injection) Outboards
 2-Stroke Outboards
(Carbureted)
All
carbureted 2-strokes must run with "double-oil" during
the break-in period (Does not apply to TLDI
models. Please see the TLDI break-in chart listed
below). Normally your Tohatsu outboard uses
a 50:1 oil/fuel mixture (1 pint of oil for every 6
gallons of gas). During the break-in period you should
use a 25:1 oil/fuel mixture (2 pints of oil for every 6
gallons of gas). See our
oil/fuel
chart for more info on the 50:1/25:1 ratios.
Tohatsu
2-stroke outboards use TCW3 oil which is specially
formulated for 2-stroke outboards. Do not use automotive
motor oil or any other type of oil in your Tohatsu 2-stroke outboard. We do not recommend mixing different
brands of oil (or even different kinds of oil of the
same brand). The mixing of different brands of oil may
cause gelling which may cause blockage of the filter
screens. This could lead to serious engine damage due to
the lack of lubrication.
As
a result of running your outboard with a double-oil
mixture, it is normal for your engine to emit more
exhaust smoke than normal. You may also notice oil
coming from the around the prop and/or from the exhaust
relief port hole (located near the top of the lower
unit) during this period. This is completely normal and
you should see this excess oil eliminated once you
finish your break-in period and resume the normal 50:1
oil/fuel mixture.
After
your break-in period has been completed, you
should change your lower unit gear case oil.

4-Stroke
Outboards
CAUTION: Tohatsu 4-Stroke Outboards
DO NOT come with
engine oil already installed. You must add engine oil
before attempting to start your 4-stroke outboard for
the first time. Failure to do so will result in extensive damage to your outboard.
We
recommend using Genuine Tohatsu FC-W 4-Cycle Outboard Oil
(see our FAQs section for more information). Use
unleaded gasoline only (89 octane or above is recommended). After your
break-in period has been completed, you should change your lower unit gear
case oil.

Note:
This outboard is equipped with an Engine Oil
Warning Lamp. When the warning lamp is off, it
indicates that sufficient oil pressure is present.
If the warning lamp is on (red light is on) or
blinking on and off, immediately shut down your
outboard and check the oil level. Replenish as
needed. If oil level is at the appropriate levels,
consult your Tohatsu dealer for assistance. Never
run your outboard if the warning lamp is on or
blinking on/off. |

TLDI
(Direct Injection) Outboards
TLDI
models are direct fuel injection 2-strokes (no
carburetors), therefore, break-in procedures will vary
from a standard carbureted 2-stroke outboard.
