Full StarEmpty StarEmpty StarEmpty StarEmpty Starwrong part/hassle for return
by Daniel from Antelope, California on June 23, 2012
I'm extremely displeased with the return system. It took three telephone calls to get my email explaining the return process and return number. The instructions are a hassle and it appears they are looking for any excuse to not return your money. This is the most difficult online company I have dealt with and I purchase continually online. As of today I know my product is in their possession and I have not heard from them in any regard.

Full StarFull StarFull StarFull StarFull Stargreat thermostat kit
by James from Fallon, Nevada on September 27, 2012
My boat motor was taking forever to properly warm up. I realized the thermostat was stuck wide open leaving the motor running very cold, so I ordered this kit. It was promptly shipped, fit perfectly, and was relatively easy to install. Boat motor now heats up quickly, and runs much better being at the proper temp. Great price on everything you'll need to replace your boat thermostat.

by Daniel from Hills, Iowa on July 06, 2012
I haven't had a chance to run it in the water yet but it works on the muffs. Not too much to say, it fits right and was shipped quick. Shipped out of Ankeny, IA and I live in Hills, IA so I had my parts the next morning.
