how do u check timing in a 40 hp yamaha 2 stroke
50:1
The mixture ratio for Yamaha outboards is 50:1 gas/two stroke oil. That is approximately one pint of gasoline to a plastic coke bottle cap full of two stroke oil.
A non oil injected, 1990 model, 2 stroke Yamaha outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
An 1986 model Yamaha outboard requires a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
Combustion piston engines can have two different work cycles, 2-stroke and 4-stroke. 2-stroke tends to have a better power to weight ratio, but pollute more. A 4-stroke outboard is simply an outboard engine that works the same way as a car engine.
any good quality two stoke oil including outboard motor oil
all Yamaha blasters are two stroke
4 stroke. A Yamaha Blaster is a two stroke and so is a Yamaha Banshee but not a warrior.
The correct ratio for 1991 85hp Yamaha is 1:50. 1 liter of oil for 50 liters of fuel.
Two Stroke.
Two Stroke
