Easy to look up and order

Have not had time to install, I will let you know how it turns out. Thanks

Good price and fast delivery

Good job

The item I bought was one to replace something I thought I had accidentally thrown away. A couple days after the boatplicity item arrived I located the like item I already had. I initiated the return process with boatplicity, as I no longer had need of the item. I completed the return request stuff and it said I would be contacted to continue the process but no one has contacted me.

Quick delivery and great customer service

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Good

Thank you. You are cheaper than West Marine Pro, (although I have to pay shipping,) and faster than Amazon. My poor planning of immediate boat projects, and your products and ease of ordering and two day delivery work well.
