Deck Drain plan 20 Center Console

[JW-Tex]

My 1969 20 CC has a solid original deck. I will be eliminating the motor splash well and adding deck in its place. I plan on putting a well at the transom (maybe 2 gallons) that will sit below the deck level and have a bilge pump in it. My plan is for water on the deck to end up in the well and when the well is 1/4 full the auto bilge pump to kick on and drain it.

Additionally, I will put two large thru hulls in the transom about 2 inches above the deck (I will check the waterline prior to installing). My plan is that if I took a big wave the water will exit via the two thru hulls and bilge pump in the well.

The boat will be trailred. Please provide input on this plan positive or negative.
