Engine flush and winterizing system?

califco

I'm looking into installing a Perko engine flush and winterizing system, anyone has any experience with this system? Is there a different system I should be looking at? 
I have two 350 MAG MPI horizon engines. I live in Michigan so the boat is used on a lake.

The Perko will work fine and save you or your techs time = $$$$$. I have held one in my hand and seen several installed. My only concern and I' m sure it could be avoided was to make sure the techs didn't step on it during maintenance as it will not tolerate that.
