I am a relatively new SeaDoo RX owner, and have never had a ski quite like this one. Just bought the ski and took it for it's first ride yesterday.

Everything ran great on freshly rebuilt engine, however, about 1-1/2 to 2 gallons of water came out of the drain plugs when I pulled them after riding!:(
All of this water looked to be in the channel beneath the engine compartment when I opened the seat, so I don't think any water was ingested into the engine... & it ran great.

I reached out t every PWC mechanic I could find in the area, and all are too busy to take a look to diagnose or repair with/for me since the lakes are back up around here. :facepalm:

I plan to take the ski to the lake, leave strapped on the trailer, and leak test with engine off and then while running to see what I can find it this weekend.

I have never owned a ski where I could not physically reach all of the water connections without removing parts of the engine/intake/electrical. When looking towards the back of the ski, there is a black box (assuming an air box) up top, and then an electrical box connected right beneath it, and then another box with an acronym on it.
Question1: Can anyone tell me how to reach the rear of the inside hull of the ski to leak test without damaging any of these parts? I attempted to start removing some of this stuff in my garage, but wound up removing the front cover of the electrical box with a rubber gasket inside & it wouldn't fit where it looked like it belonged.
Please let me know if anyone has a video of "how to", manual, or can explain very well how to remove this stuff or if it is even necessary.
Question 2: the rubber gasket from the electrical box did not fit inside the grooved channel of the front cover that came off, so I installed the rubber gasket/seal first, and then put the cover on the main box with wires and main connectors inside. Is this the proper way to install the rubber seal? It would not physically fit inside the channel of the cover (it was too long and would not fit flush). Do I need to remove, cut the seal to fit inside the electrical box, and then reinstall? I don't want to get water in there.

I appreciate any advice that can be shared with me - it would be great to isolate this issue down and be able to repair relatively simply.
Also - if you happen to live in the Austin, TX area and like to work on PWCs; please reach out to me as it would be great to have some friends who are a little more tech-savvy working on PWCs than I am at this point.

Cheers and Thank You, :cheers:

Pull the seat off and back down the ramp like you suggested. Leave it tied to the trailer and you will get the ski deeper in the water.

It could be a hose as the engine is a fresh rebuild.

Could also be the carbon seal. Are you familiar with the CS?

For your question 2, I removed this cover twice on my ski and as you say, the seal doesn't fit in the front cover. So I did exactly as you did and it went in OK. The first time I removed the front cover, the seal remained around the box itself but the second time, I had to replace the seal around the box itself because it wouldn't fit in the front cover.

I am supposed to go pick up my ski at the dealer on Monday or Tuesday and I will ask them as I asked myself the same question.

I had a similar problem with water entering the hull and found that the seal around the drive shaft near the flywheel had come out of the holder. Pushed it back in and made sure it was secure and haven't had a problem since.
 
Thanks for all of the info and feedback.
I plan to get to the lake this weekend and "leak test" (last weekend didn't work out).

Coastiejoe & XP 787: I am not familiar with the carbon seal but have heard the term thrown around quite a bit when people are diagnosing leaks. Secondly (pardon my ignorance), what are "welch plugs?"

Benji: Glad to hear I'm not the only person who has had the same deal with the electrical cover seal. Very curious to hear what the dealer tells you.

Will post any updates I come up with ASAP and thank you again for everyone's help and replies. It's awesome to get more help with one post then the 3 dealers I visited combined who told me they wanted a $3k deposit to work on the skis because they're too old!

Cheers,

Rich
