Dear Steve…I wanted to send you a few pictures of the my boat. I moved it to Colorado two years ago from sunny California and was immediately concerned about winter storage. Tha boat is kept in an indoor storage facility which has 110v outlets but no heat. Since it has two motors, winterizing it is a pain. I decided to try your larger Xtreme heater. I followed the directions and pointed the fan area toward the transom and just plugged it in. The temps in this part of Colorado get down below 0 degrees regularly so I blocked all air inlets, taped over water inlets and covered the exhaust and drives.

Thanks much for a great product. I feel good knowing that the system has a proven track record for safety and also will protect my pride and joy from the damaging effects of such extreme temperatures.
