Reviews: What Customers say about US Boatworks:

Look No Further

I needed some Yamaha prop parts for my 1994 P-150, and the guys at US Boatworks took immediate care of my situation. I had been shop hoping all over the KC area with minimal success, so I called US Boatworks who told me they could fix me up. They looked at my prop, found some matching parts that were reasonably priced, and off to the lake I went. Needless to say I was a happy camper. I will be back for sure.”
– Joe Conner

Professional Staff

Professional, kind staff. I’m very happy with the service I received. They bent over backwards to get my boat done on time at a great price.

I highly recommend.”

Helpful & Have Older Model Parts In Stock

Very helpful in finding a gasket (which they had in stock) for an older motor. So long as you have the correct information, that they need, you will find these guys to be very helpful and will bend over backwards to help you. Took my boat down there some time ago for repairs and was treated very well. Their website is excellent for looking up parts for older motors as well. I spent hours on the web until I found their site which help me to locate the part I needed in a matter of minutes. Thanks to the guys at US Boatworks.”
