where is the oil filter on a 1989 yamaha motto 4
lowest possible point on the engine
An 1986 model Yamaha outboard requires a 50:1 ratio, roughly one pint of 2 cycle oil, to six gallons of fuel.
the front fork oil leval is to be set at 130mm from the top of the fork (air gap)..with the fork spring out ..and the fork fully collapsed ....
Change the oil.
I use 20w- 50 non detergent oil for motorcycles in hot weather and 10w-40 The Maxim holds 3.7 quarts when you change the filter which I recommend highly.
