Review on Attwood 1731 4 Blower White 3 Inch by Mark Patterson

Firstly I didn't buy for use in a boat, but for use as an exhaust fan for a homemade humidifier. Made a tent to add on. It's too complicated for this purpose, but after purchasing - HiLetgo 12V40V 10A PWM DC Motor Speed Control Switch Controller Switch Voltage Regulator Dimmer for Arduino - it completely solved the problem, great fan, powerful when you need it, but it works with variable control . The handle I bought fits perfectly, will buy again.
