Thank you very efficient

Ease of use site

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.

I received my part. Fit perfect , installed and ready to go. Happy Boater. !!? Thank you.

boatplicity provided the prop paint product that I needed and wanted at a very good price. Why pay the overpriced WM item? Ordering was easy, the free shipping option was a great feature and helped me go with boatplicity for my order. Shipping time was good. Didn't need it immediately and I loved the opportunity to use their offer.

User friendly site and competitive

Everything was easy and quick

Seamless purchase, fantastic price!
