Good service and good price.

This company is super fast to get you your order! I ordered online and figured it would be at least a couple days or so until my order would even get processed. I think they overnighted it to me! The package showed up undamaged and sealed. Unfortunately, I may have to return the product as I am thinking I would like the spikes shorter but that is no fault of Thmotorsports. Hopefully their customer service is as superior as their ordering and shipping. At this point I would definitely shop there again and recommend them.

This was one of the few places I could find that had these in stock.

Quick, Easy to use, great prices! Very excited to have found this!!

I just never do top scores

Easy to find

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.

The part description was accurate and we got the parts in a timely manner.
