Needed a new water box for my rrp pipe. After looking at a few different ones and seeing a jetmaniac laydown water box in Daytona I had to have one. The build quality is perfect. I also like the shape and size of it, it fits really nice in my ski. Another positive is how quiet it is compared to the rrp box it replaced. I'm running an unrestricted waterline to the water box and it isn't much louder than a superjet with a b pipe. Even with that much water running to the water box it preforms great and it dose a great job of keeping water out of the motor. 10/10 received_1061004800945691.jpeg
 
Love my jm waterbox but my neighbors hate it. I got threats so I I tried a ss 2.25 in line silencer off ebay in conjunction and problem solved. Might be useful for someone. Btw multi million dollar homes on canal we ride.

Adding another positive review to this thread. I just had a chance to test my JM laydown box in Daytona. I swapped from an RRP box also after reading about the problems with water ingestion, not to mention noise.

After the ski sat on shore with waves crashing into the rear, and then lifting the rear to drag it into the water (waves still hitting), zero water found it's way around to the engine.

Another note: even though you need to have a reducer to go from RRP chamber into the JM waterbox, you are not restricting exhaust flow because the ID of the RRP chamber is less than 2" since the walls are so thick.
