im winterizing this motor and want to use fogging oil,dont know where to spray it,in inj port,spark plug holes or both,and if in inj should motor be running,also looking for motor diagram
you dont spray anything into the air valve.
treat the oil with crankcase stor-n-start.
stabilize the fuel in the hull.
run the engine about 10-15 min on the fogging mixture reccomended by mercruiser or Volvo for EFI storage.
this is added on to first post,book say to spray fogging oil alternately into intake silencer or fogging hole of silencer cover.dont have diagram of motor to know where they are
I know I have spelling issues.
DO NOT spray anyting into the air valve.
wont make it to the top 3 cylinders but the bottom one will look like a turd in a punch bowl.
you have the WRONG book.
yamaha actually says drain the VST, we have had issues with that over the past 10 years.
what we do with the EFI motors is fog them with the solution reccomended by mercruiser EFI and Volvo EFI and it actually works.
I just cant remember the mix ratio but if ya PM donS for it he has it.
then we can tell you how to apply this mix to your yamaha.
