Sorry pushed wrong button.
And heat installed . the units were almost new from a Lagoon
45. I was just Lucky to find these units at a reduced rate. When I was looking I went to the Ft lauderdale boat show
and the vendors were very helpful . If I had not already contracted for the used units I would have bought threw them . I cant remember the vender as that info is on my boat in fl. I am at my land home in ark.
Any way the best I could learn was for the air to have there own thru hull
fittings , Also when you have the boat hauled cut thru hulls for a water
maker and a gen set. You may not plan to install these now but if you want them in the future it will be in place . I have a 40' leopard
and installed radar
,solar ,TV antena ,and gen set .
all in all about 30 K . I would have been much further ahead if I had bought a boat with all the bells and whistles.
