The last two times I have been out on my 2006 RXT it has taken on quite a bit of water in the engine compartment. I have had to open the drain plugs upon putting it back on the lift. It drains for a good 3 minutes. Previously, it never took on water and my other RXT remains dry as a bone. There are no exterior cracks, holes, open areas for the water to get into the compartment. Any ideas on what or where the water is entering the engine compartment???????

Put it on a trailer with the seats off, back it down a boat ramp so it's in the water. Put your vehicle in park and apply the emergency brake. Now start the RXT and look inside the hull with a flashlight while it's running still firmly attached at the bow to the trailer... see if you can see any leaks around any of the hoses or any water coming in thru the carbon ring seal at the front of the jetpump. Just let it idle the entire time, that's what I'd do if it were mine coming up with that much water inside the hull! And having a friend on hand to help hold it straight on the trailer wouldn't hurt a bit either.
And please look into putting an automatic electric bilge pump in your RXT, the OEM water extraction system isn't high-flow at all it's only meant to remove whatever water normally seaps in thru the carbon ring seal (all jetpumps leak a little water into the boat by design to keep the seal cool and lubricated). The OEM system won't protect you from sinking if a hose develops a serious leak or the carbon ring seal fails or if the forward intake grate bolt falls out of the grate (the hole goes all the way thru to the inside of the hull... ask me how I know this!!!).

ps. Where in Texas are you from? I'm north of Houston a bit, and go up to Lake Livingston every chance I get with my boats!

I would think that seals would be a suspect, however, I am new to jet skis, so I don't know for sure what all the possibilities are but I am good a troubleshooting and I know how I would approach it.
I would put it in shallow, weed free, water about 2 feet deep, remove the seat, and wait for a while to see if water is getting in when it's not running. You might need a step stool to get high enough to see all the way to the bottom of the engine compartment with it in the water (I know I would). If no water gets in, then I would tie it off using the rear tie downs tied to an anchor (the kind with an auger blade that screws 3ft down into the lake bed) and then start it up and see if water is getting in while it is idling. If I saw no water getting in that way, then I might throttle it a little bit, just above an idle, because in only 2 feet of water I wouldn't want to risk sucking something in. You might need someone else to throttle it while you look for water getting into the engine compartment. Even if I couldn't find weed free water to run it in, I would still at least look at it with it just floating in the water.
I would hope to see exactly where the water was getting in and then go from there. If I couldn't see the leak, or I couldn't find a suitable water location to do the run testing, I would call around for a service shop with a test tank, find out what their labor rate is, and maybe pay them to look at it for an hour under various throttle conditions all the way up to full throttle. Maybe they can identify the leak.

Thank you all for the ideas I am planning on spending time this weekend with it both in and out of the water, running and not running, on the lift and in the water looking for these leaks. I am hoping it is a hose, fingers crossed.
I am on a lake outside of Dallas, so little far from Livingston.
