“I’ve been a longtime customer of Frahm Marine Werx. They were recommended to me when I first got my bass boat about 7-8 years ago. While they mostly take care of walleye boats, they took a chance on me. Fast forward to today and I’m still taking my boat to them. That includes moves to Western Nebraska and now Milwaukee. I just can’t find a place as good as Frahm’s for service.

Joe has always taken the time to explain,in detail, what’s happening with my boat, whether minor or major. And by working with them this long, we’ve been able to get ahead of any potential problems. Joe laid out a clear schedule of required maintenance my first year and we’ve stuck with it. And now that my boat is 20 years old, we’re still tweaking things like plugs, propellers, etc, to keep my boat in optimal condition.

I can’t recommend Joe and his crew highly enough. They specialize in service and have never let me down.”
