I found the product I wanted, and the order was easy to complete. All info was clear and precise, so did not have to speak with anyone! Acknowledgement of the order was prompt and was filled and shipped almost immediately. Packaged well and received within a few days. I certainly will consider the seller should the time arise in the future.

Great start to finish.

I have one of these on another boat. I love it and it's saved my lower unit more than once when I unexpectedly found a stump or hard bottom.. It also allows me to run with the motor higher because if the set back.

Good price, fast shipping

quick and easy experience
