Looking to fog out and run antifreeze through my fresh water cooled ,fuel injected MerCruiser 350 h.p. M.P.I.- I was told to add about a quarter of the capacity of two cycle oil to the water separator and then run about 8 gallons of anti freeze through the raw water pick up hose. My question is, does that sound correct and will the two cycle oil reach the block and cylinders with 8 gallons of anti-freeze run time. Regards Andy

Follow the factory service manual.

Drain everything first before you add antifreeze with a funnel
