Listen..!! This F20 Yamaha as more than 362 cc like was the previous ones till 2020. it's now got 462 cc and the displacement is worth to see , because now you can maximise your propeller to the max with a big pitch. and you have the same motor as the F25 witch is also 462 cc. Amazing stuff again as you can convert your F20 to a F25 by changing the computer Box
Usually the oil drain is on the leg of the motor on the back of the engine. Just follow the leg up from the prop and there should be a drain plug recessed a little in the leg.
