Very well made just not that great on the boat and if you try it no return .

Would recommend a more central ballast. Can’t use partially filled and full is too much on the rear.

We are very sorry to hear you weren't happy with the performance you achieved with this upgrade. We agree that this bag alone is not a solution for most Yamaha models and that they will require more weight forward in the boat.

That doesn't take away from the quality and performance of this bag though, so please take that into consideration when reading this review.

Surf’s Up!

I received this bag earlier in the week. I’ve been putting this off for a while because I already had two 550lb bags, so it was hard to justify the spend on this bag and the Supa pump. When I saw the sale, I decided to go ahead and get it. Wish I would have done this a bit earlier. It’s definitely easier to use than my big round bags. This things sits on the platform well and helps my boat make a great wave. I’m using it on a 2019 212X and it works well with the 700lb locker bag filled.
