If we are talking about a 2 stroke engine, a TCW-3 rated, 2 cycle oil is required. For a 4 stroke outboard, 10-40 wt. oil is usually recommended.
Cracked block or blown head gasket.
can someone tell me what the gas to oil mixture for a 48 spl Johnson boat motor is please
The boat does still go full throtle
50:1
It will flow over the sides
If there is no oil tank on the engine, the oil must be added to the fuel.
The gas to oil mix ration for the Johnson boat motor is 40:1 for this year and style outboard. Some people might suggest 50:1 but this can cause your motor to gall and may cause you to loose a ring or two.
The length of a motor boat is not restricted
most likely 50:1
50:1
50:1 otherwise 51/2 oz oil to 2 gallons.
only if there is a serious engine problem. A boat motor is cooled by lake water instead of a radiator and coolant system. The lake water is pumped into the motor's cooling tubes and pumped out through the exhaust. The only way I can see that there would be water in the oil is if the motor has a blown head gasket or a cracked valve.
