Thank you
from Mike Dieckhaus, 6 months ago

Ed did a great job finding the perfect boat for us. One of the most honest salesman I've ever meet. Even after the sale we had question about circuit pannel and Ed stopped bye on his way home to help us out. Great experience all the way around

Thanks Big Thunder for your great service.

Big Thunder Marine
I would like to thank Gary at Big Thunder. I had a problem with 1 of my motors today and when I called they said if I could get it to them they would take a look at it. When I got there Gary diagnosed the problem and said it was the fuel pump. They had the $1200.00 part in stock. When he started to uninstall the old one he noticed the clip that holds the wires in the fuel pump had been broken and someone used tape to fix the problem. So the wires had just come disconnected. He could of went ahead and installed it and told me he also had to replace the clip. But he was very honest and told me he had good news. The almost $1400.00 repair would only cost around $60.00 for time and new clip. So I would definitely recommend Big Thunder if you have any problems with your boat. Thanks again Gary for your great and honest work.

Awesome Sales experience

We bought a new Manitou from Sam (and Tim) at Big Thunder Marina. Our experience couldn't have been better. The price couldn't be beat by our hometown dealer, the communication prior to the sale was excellent, and the after sale feeling was "Top Shelf". Thanks Big Thunder for everything.
Sincerely,
Sean and Debi McKay
