Amazing product! Not even West Marine carries this bad boy.
Great product. Only caveat is that the ports need to be open to snap on the sprayer and two-hose flusher due to the water pressure. No biggie, this is a great time save and high quality product.

Seems well designed
Works well, is really light. The length of the hoses to the individual engines is just a out right.

Works Great
This is a durable product that works exactly as it should. The quick connects have also been very durable. I went through about three sets of the chain store connectors before I found Flexzilla. They all had metal springs that would rust and fail. These don't have any metal part. I've been using them for over three years at this point. My friend just got a boat and I'm buying him one to congratulate him.

Weak flow
Great idea, product looks greats great; however, very weak water pressure to push through twin motors. One motor would not even pee. I don’t not feel comfortable using this product on my boat. Will return .

Nice setup and exceptional quality
This is a very nice twin hose setup - unfortunately my dock water pressure is not sufficient to supply enough water to a twin Yamaha jet on an FSH 255 setup - I get an overheat warning while flushing. The hoses and fittings are high quality and the setup is outstanding - I'm very disappointed it didn't work for me!

The order is missing several key parts rendering the flush kit unusable. So far despite emails it has not been resolved!
