Under Chart table
I installed ours under the chart table, ran the water intake from the engine water thru hull, by way of a three way valve,(no I cannot run the engine and the A/C at the same time, but never have had the need either.) I also keep the engine start key on a peg in the engine box, to be sure the valve is turned. also have the duct into the aft cabin,and two into the main cabin, waste water and the condensate is run overboard behind the unit, just above the waterline,The condensate is a problem with the H34 because of the inner pan, hard to run the hose into the bilge.I built a platform for the unit from pressure treated 2x2's and a piece of plywood treated with epoxy, on top of the plywood, under the unit, I added a piece of rubber mat (like a truck bed liner) to help deaden the sound. If I can help in some way E mail me off the list.Good luck, well worth the time and cash, best improvement you can do!
