Pro Air Intake Mod....
As many of you know by now, my Riva Pro Intake took on massive amount of water into the motor. It cost me a 2nd place finish and took all night to repair the problem. Also snapped a plug off in the head.
Water had half filled my inter-cooler and was puddled in the throttle body and base of the inter-cooler.
Some members from here helped me through the night getting my ski ready for the next round the following morning.
Things went well on Sunday after modifying the Riva Kit to no longer pull out side air. It is now safely pulling from inside the hull.
Water was so bad it killed the motor and turned the oil to moka color. Took several oil changes to get it to a some what clear status.
It has been concluded that Riva must have been tested with stock steering that aids in protected the splash box. With the UMI it leaves a huge hole allowing MASSIVE amounts of water into the air intake system.
SO CAUTION RIDING WITH UMI AND THE RIVA PRO INTAKE. This has happened twice to me.
Sure I put it in the most extreme conditions over the weekend but this modifications failed to keep clean safe fresh air.
I'm sure I did something wrong and this failure can be contributed to my inexperience or insane riding habits......
Some pics from the sickness we endured this weekend.....

Well i was anticipating that one. Sorry to hear it happened to you bro.
Nothing better to get fresh outside air though for sure. I can't wait to see your fix.
Riva's "performance" kit will be shipping end of week for us rec riders.

Oh ya on the Outerware but this 250X can suck a golf ball through a garden hose.
It even comes with a splash box cover but with the amount of water coming over the hood it flood the compartment making the intake into a wet-vac.

Yep, look out folks.
I come from several decades of Glamis, CA trips back when you would just cut the pan floor out of a vee dub, weld a hoop, and call it a rail. Outerwears were made to keep sand out originally. We all used to use panty hose before outerwears came out. They inherently sheen a little vapor, but just like Skip said. Oh man. I feel for ya.
Tyvek I wonder??? I don't think anything will stop water entering that mod - ever.
I poster earlier some calc's on volume requirements not taking consideration of the SC, well, my adjusted calc's are between 500-600cfm @ 8000rpm (golfball/gardenhose)
Cool air is key, but keep'er dry!
