It's just gas after the box, but is wet to the box. The exh from the engine
will still mix with water
, then exit the waterlift to an undisclosed location above the waterline where the magic of the box works. After that point it can go up/down/left/right so long as the drain line goes down and out (as short as possible and above the waterline so you can see the water). I should also mention that the drain line needs to be larger than your water
supply to the engine
, say 1 1/4" for a 3/4" supply.
The one I built was made of 1/8" doorskins for a basic shape, except for the bottom. I built it of epoxy
and glass mat inside and out (more inside) then adden the three fiberglass
pipes and base at the bottom, but used all mat and cloth for this part. Worked like a charm and I hope is still working to this day.
