This jiggler/shaker tube device is awesome!
It works as advertised.
I bought the "Flotool" brand "Shaker Siphon". It has the brass shaker device.
My boat is a Bayliner 185 with the sport seating, so it has the large padded sundeck.
I sat on the sundeck and positioned the gas container next to me. I put the open side of the tube into the boat's fuel neck about 18".
I stuck the end with the shaker into the gas container. I learned that you have to shake it vigorously up and down to get the flow going.
Once it was flowing, it didn't take long for it to empty the 5 gallons of gas. It was maybe less than 2 minutes! There was a small amount left in the gas container after the siphoning stopped. No big deal. Such a simple device and it works great.
No mess, very fast and I didn't have to sit there on the dock holding 5 gallons of gas as it s-l-o-w-l-y pours in.
It was such a hassle before. Especially with todays non-vented gas containers. It took forever and with all the wakes from other boats, I had to hold that heavy container while the boat was bouncing.
Never again! I now have the shaker tube!
Thanks "oldjeep"!
I bought two of these and I'm gonna use the other one for cleaning the tropical fish aquariums.
Oh, and thanks to everyone for all the posts!
