hi, i have a new e-tec 60 repowered for my boat. and it sat on the saltwater at all time. my question is can i flush the engine with freshwater in tilt mode? or do i need to tilt down the engine before flushing ?
You can flush the motor in the tilted postion, not running, but it will not drain the engine block unless the motor is lowered to vertical. You cannot do this in freezing weather.
What some people do whose boat is left in water and they have to tilt the motor for storage is to flush the motor, not running, while it is vertical and the lower unit is in the water. When done and the engine is fully drained, they tilt it up and hose off the gearcase area as best as posible.
