I want to post my recent experience with a new Nicro day/night vent.
First impressions are that it looks well thought out and well made. The instructions that came with it are above average.
I bought a hole saw and mounted it through the forward hatch of my San Juan 7.7m. I used marine sealer to glue it to the hatch. Worked great, but about four weeks later I noticed it was making a little noise. I was not surprised, as I had read about a lot of motor failures. One week later the motor was dead.
Not wanting to deal with the hastle and expense of returning the unit, I took it apart. Disassembly is relatively easy, three screws and shake/pry the solar panel off. Then pull the fan blade off, remove one more screw, remove switch nut, slide battery contacts and motor out. Testing revealed that the motor was bad. I took it apart (I've taken lots of small motors apart) and cleaned and lubricated it. I was surprised that the armature had three capacitors mounted to it, never saw that before. I used lubricating oils designed for small brushed motors. One oil for the brushes and one for the bushing. It's working again. I did have to resolder one wire as I broke it while fiddling with the motor.
I hope this helps someone. Next time I'll post some pics.
