    Riva's 4" under seat intake & water

    I'm curious how much will I give up in the ability to really ride waves, etc with Riva's 4" under seat intake? Would I be better served to run a 4" hose of some type into the spot where the Riva 3" used to go? I'm trying to get more air into my Rude without giving up anything.

    I would go 4" front intake for peace of mind, but that's just me. Most will argue that unless you drill flo-rites into your grab bar, the chances of water ingestion with the RIVA rear air intake are unlikely.

    I would not recommend rear air in a surf envrionment. Like fizzle said if you want peace of mind go with a 4 inch front. Jammer might be able to chime in with getting fresh air into the front of the ski, he modded his hood.

    I rode again with the offshore gang to Catalina and back on Sunday and have done about 20 round trips to Catalina and back in all knids of conditions and have my copy of the Riva 4" rear air intake and have NEVER had any water ingestion problems in the offshore riding/racing environment. However in sprint races I have had water intrusion when other racers (much faster and more skilled than I) have passed me their jet spray from the sides has caused my engine to cough and sputter momentarily. No damage just a temporary unintended slow-down for me. So for those kind of races I will switch to a 4" under the front basket air intake. Again I have no problems in the ocean even with good sized swells as I keep my ski pointed into the waves as much as possible. Just my thoughts.

    I lost about 50 rpm's up front but NEVER have to worry about salt water intrusion.

    Here's what I did. A little overkill but I like it.

    You could replace the alum pipe and elbows with Kanaflex 620WD hose and accomplish the same thing. Look for 'intakes' and 'kanaflex'

    With the rear air setup or with a stage 1 intake mod are you restricted in how you can ride? With a stage 1 air intake mod can you still horseplay with it and if it gets flipped still be good to go? Or is there a huge risk of taking in water over the stock setup if the boat gets flipped?
