Very happy with Flushmaster.
Just purchased a second boat that does not have a flush system built into the boat. Figured I’d try the Flushmaster system for the twin 300’s on this new boat. I have to give Flushmaster a 10/10. With the quick disconnects installed on each engine it takes 30 seconds to hook up the hoses and start flushing. My other boat has a very expensive flush system built into the boat, but the Flushmaster is a fraction of the price and does the same exact thing. You don’t have to flush all your engines all the time, just the ones you want to keep.
