Yamaha Vmax HPDI trim fluid change

[bnagel11]

Does anyone know where the drain plug is on a Vmax HPDI for the trim fluid?

There is no drain plug.

There is normally no reason to drain the oil on a scheduled or "preventative" basis.

To get all of the old fluid out the unit would need to be removed from the motor and dismantled.
