''Awesome discounts on fishing reels and GPSs. Plus they have next day shipping. The convenience of online shopping is awesome, especially since it's getting harder to get around in store.
They made sure I got the electronics I needed and all the hardware for the install. They even do repair and installs, so I ended up hiring them for the work I needed done on my Mercury. Awesome experience.''

JAMES

"Great experience! I Was looking to purchase a head gaskets for my Johnson 150 hp outboard motor. Mike & Ashley researched parts I needed and come to find out they turned me on to my outboard engine used O-Rings to reassemble my head covers and provided me with parts and torque specs! Thanks! 100% positive feedback and Recommend this Family Business if you need Marine Supplies."

SCOTT

Family owned and operated, which is a huge plus for me! I was browsing the website looking at Garmin gps units, their prices are great and competitive! I reached out to them to ask where I might find a hard to find lower unit part I was needing. They had it in stock! If they don’t have something in stock, they will get it asap! 100% recommend and I will buy from them again in the future!
