Building a Sea Chest

[mbmcdermott18]

Cayman, I share your concern on the inlet size. I would prefer to have two 1.5" or 2" inlets. MY boat has two 1" raw water intakes that are glassed into the hull, changing the size of the intakes would be a much larger indertaking. I am not opposed to it but I would like to make sure it will not work like this.

As far as the design goes it should work as follows:

the two one inch raw water through hulls will be plumbed to a gemlux ball valve then hose ran aprox 18" from the valve to the 90 degree through hull on either side of the chest.

The pumps in the chest are plumbed to two livewells. One livewell has two pumps. The are connected to a thread to barb adapter which threads into the groco flanged adapters which have gemlux ball valves and are then plumbed to the livewell.

The chest will have a 1/8" mini ball valve in the lid to allow you to vent the chest.

the vlalve in the rear of the chest is going to the shurhold washdown pump.
