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 could lead to serious engine damage due to the lack of lubrication.Īs a result of running your outboard with a double-oil mixture, it is normal for your engine to emit more exhaust smoke than normal. The mixing of different brands of oil may cause gelling which may cause blockage of the filter screens. We do not recommend mixing different brands of oil (or even different kinds of oil of the same brand).

Do not use automotive motor oil or any other type of oil in your Tohatsu 2-stroke outboard. Tohatsu 2-stroke outboards use TCW3 oil which is specially formulated for 2-stroke outboards. See our oil/fuel chart for more info on the 50:1/25:1 ratios. During the break-in period you should use a 25:1 oil/fuel mixture (1000 mL of oil for every 25 liter of gas). Normally your Tohatsu outboard uses a 50:1 oil/fuel mixture (500 mL of oil for every 25 liter of gas).

Please see the TLDI break-in chart listed below). All carbureted 2-strokes must run with 'double-oil' during the break-in period (Does not apply to TLDI models.
