      Comments about Camco Inboard/Outboard Winterizing Kit:

      Can drive you crazy but there is hope. This of this as just a convenient sealed bucket with a built in 3 way valve system. You could build it yourself for about $10 if you already have a bucket.

      This system is just a transfer tank and really does not create significant push of antifreeze into the entire engine. My application was through an inline Perko intake. This intake, sold on this site, allows the user to hook up a hose from a house water line and operate the engine. However, house water comes in under pressure. If you use the system and hook up to the Perko, there will not be sufficient pressure to drive antifreeze through the system. I had to add an inline pump in order to drive enough pressure into the motor. At this point it worked fine. In summary: Just about every system will need some other part to make this work.
