Cord is too short

Works great, however, the cord is too short! It wouldn't reach the water on 1 side of the boat.

Great Post Sales Support!

My family and I have been using two of these pumps for 3 years in salt water. We ride every weekend from June to September and the pumps are reliable. After all that abuse we needed a bit of support from the manufacturer, I reached out by email. They responded super fast and got me what I needed!!!! Thanks..... We will continue to use the pumps and bags.

Good for the money buuuuuuuuuuut........

If you like to surf with different riding styles (Goofy/Standard) then filling and draining isnt as easy as pushing a button! Especially when you have to fill the line with water before hooking up the pump to the bag to empty. Maybe I should buy two bags.

priming issues to drain

pump is hard to get prime to drain bags have to put drain hose lower than pump to get it to start pumping and then throw hose over the side end up with a bunch of water in locker. pump is fast to fill but pita to get it to drain

WakeMakers Reply: We have also seen this issue but have found that plugging in the power after the pump is connected to the bag will solve your issue. Check out this video of how to operate the Straight Line ballast pump from Tim @ Liquid Force Wakeboards - Straight Line Sumo Ballast Video
