Mericruiser 350 Mag EFI / Bravo 1 Flushing Routine
 

What's the by-the-book method for flushing these motors/drives. I have one of the few performance boats at my dry rack storage and the crew wants to make sure they are doing it right.

Thanks,

Kyle

Pull lower drain plugs and let water out....use a coat hanger to be sure the holes are open and not rusted or plugged.. Pull thermostats and pour a couple 2-3 gallons of "blue" (not red) engine anti-freeze with anti-corrosion agents..-50*F... while briefly cranking or running engine.

Store with drain plugs out and t-stat out...come re-commissioning..put plugs in..t-stats in and crank her up with flush kit or in the water.

by the book every time out would be to run fresh water( tap/ hose) through the system long enough for the stats to open then about 5 min I aways recomend salt away also but Im just happy if they flush
