Not Standard Size
by Julie from Lexington, South Carolina on July 11, 2016
The holes for this drain are not consistent with the alignment of traditional three hole Garboard drains. I was looking to utilize the existing holes in the boat transom to use this product, but they do not align and I would have needed to drill new/additional holes in the boat and patch the others (not happening). I even tried to bore out the drain's holes to see if I could get them align if they were a bit bigger (that is how much I really wanted to use this product), but that was also unsuccessful. Great concept, but poor design planning if they were hoping to capture those customers looking to replace a standard Garboard drain. Very disappointed.

One-way garboard Drain Plug
by Pablo from San Benito, Texas on November 09, 2011
Great ideas for the on both the one-way drain plug and plug. About the only problem installing this and other 1" garboard drain units is the tightness fitting them in. I'm sure everyone has to use a drumel tool,etc., to fit these. Make 31/32" units and possibly another oval unit and you'll have the perfect designs.

Does the drain plug go over my existing drain?
You can use the existing bilge hole. You would need to remove any existing hardware.

I can't find the deminsions. How large is the drain plug?
The plate is 2" O.D. and the plug is 3/4" O.D.
