I need to install air conditioning to my canopy MTI. Is this difficult to install? Any ideas on what system to use and how to rig it? I did place a call to NautiCool. I am not sure if they sell to end users or not. I want to rig it myself. Not sure how much either.

I bought a 5K BTU Cruisair unit and installed it myself on a 31 ft Formula. Hope you don't mind drilling a few holes in your boat. It cost me about $1,500.00 and around 40 hours to complete the project. (you can look it up in old threads in the Formula Forums.)

Pretty easy actually! Mount it, locate the water pump/pickup, run the plumbing to the unit, locate the thermostat control, install an inverter and run the duct work.

You don't want this....

So then I guess this is out too......

Brad you are looking for something that you can run while under way are you not. I believe the setups above are for when you are already in a slip.

OH....He's right, These things need a constant water supply and 120V.

I bought an Ocean Breeze 10k BTU with heat for $1200 off eBay included everything & digital thermostat, it took me about 20 hours to complete. The unit runs off a 2000w genset, and is not a reverse cycle heat, so you don't have to be in the water to run heat, you do for the AC...

Yeah, I need the system that runs off the engine much like a car. Weight is slight factor as well. It is going in a race canopy boat. Need to keep the cockpit cool at 100 mph.

Hmmm, in that case redneck AC
.....hold you hand up in the air and make a scoop to deflect the air to inside. Cheaper and it works!
