I just got my ski back today after having the supercharger rebuilt. I had the work done at an authorized dealer. When I took it out on the water tonight, didn't seem quite as snappy. Would new washers do that? Also when I pulled it out of the water, pulled the drain plugs water kept coming out. Probably about two gallons worth. Usually nothing runs out of them? Don't they have automatic bilge pumps? Did the tech miss a step? I just bought it a month ago so I'm not too familiar with it. Didn't see anything out of place. I'd hate to drive 140 miles round trip just for a $. 99 zip tie.

I have spent hours recently reading up on as many threads as possible on this SC that we're married to, and I dont recall anyone sayn yay or nay on a re-build break in period. I haven't done mine yet, so I can't say. I'm sure the advise will find you soon.
Auto bilge pumps aren't standard issue, so somethings not right. Was there any other work done besides the SC rebuild?
 
No other work was done to it. I forgot to ask for a parts list of what they put in. I'll have to stop in next time I'm close to the place.

Sounds to me like you have a new problem ... cavitation. I would inspect your carbon seal, as this is likely we're your losing that snappiness and where the water is coming in from. Is the ski hitting max rpm?
 
This isnt adding up for me...No prior issues, SC rebuild...lost its snapiness and is taking on water, yet pops max rpms AND 70 on chop?
Is the loss of snap outta the hole, or thru the band?....How many hrs on it?
 
Its been a couple of weeks since I have ridden. So maybe it's just me. Was scared of the ceramic issue. Bought with 100 hours on it. Has 104 on it now. My main concern is where the water is coming from.

Start with water issue first. What i do when trying to find a leak is put the ski/boat on the trailer and fill the hull up with garden hose. Let it fill till water is over driveshaft. Then the leak will likely present itself.
 
I agree with Bman, leak first, then performance.
Another leak detection technique is to put it in the water and leave it 'trailer connected'. Pull the seats (of course) and see where the water comes in.
 
Yup your thinkin what im thinkin. Haulin 10 gallons a water will affect performance lols. I lose about 8 mph with my ballast tank full (does toss one hell of a crispy wake though) ... agreed on trailer method too i have metered water lolz!
 
I was thinking it is a hose that didn't get reconnected after the s/c rebuild?

Okay so I have the engine cowling off how do I check for leaks on the lake cooled part of the system?

A thorough engine compartment inspection would expose disconnected hoses and such. Isn't your RXP 'closed loop'? Not sure what you mean by 'lake cooled part of the system'.
Are you thinking the hose technique or are you putting it in the water?
 
Hose technique, yes the engine is IC, but the exhaust runs on lake water. I couldn't find any loose or disconnected hoses. To my best guess, they botched this fitting up with the zip tie on it. The hose seems to be on tight. Although it has one of those pinch clamps on it. It seemed wet all the way around it after I ran it on the hose. If that's the case they'll have to repair it bc I don't have the stuff to do that.

What were the results from filling the bilge, or putting the unit in water for leak detection? The pictures are not conclusive....I'm not sure what it is you're trying to show.

Did you look into the hull to see if water was shooting out anywhere inside while you were running it on the flush port with a waterhose? If that hose got wet, the water came from somewhere!

To get the supercharger out of the engine the exhaust J-pipe had to be unbolted from the exhaust manifold and the waterbox unstrapped and slid backwards about 5 inches to get enough clearance to pull the SC out of the engine completely. They likely didn't get it back together correctly somehow... and if you're leaking exhaust water inside the hull, that would account for all the water in your hull and the heavier/sluggish feel you describe. If you were closer to the dealership I'd say take it back and make them fix it! But I understand gas isn't cheap anymore and neither is your time so you may be able to find the problem yourself but you'll have to see where the water is coming from... run it on the flush port again, use a flashlight and try to see where the water is leaking from that covered that hose!

Your SeaDoo RXP has a water extraction system but it's not very high flow it doesn't suck alot of water out quickly enough so the water built up inside your hull leaving you with gallons of water to drain out once you got it back on the trailer again... my RXT doesn't have an ounce of water in either side after riding it for a few hours and putting it on the trailer opening up the drain-cocks, it's practically dry.

You're leaking cooling water from a hose in there somewhere and it almost has to be related to them pulling your supercharger out to rebuild it!

ps. This is another excellant reason to have an automatic electric bilge 600+gph bilge pump in your watercraft, it would alert you that you're taking on water when it starts pumping water overboard suddenly and give you more time to get it back on the trailer or beach it... a burst hose or one that's come off (not clamped properly) can sink your watercraft in a hurry if all you have is the OEM water extraction system! I cannot recommend the installation of an automatic electric bilge pump enough, the peace of mind is just priceless! If it goes to pumping water out, you'll know you're taking on more water than the OEM water extraction system can handle and that means something is WRONG inside the hull...

The water box, thats the part that is metal in cased in like a fire retardant foam & plastic right? Also what is the best bilge pump? Do I put it on a switch, where do I place the lines, switch, etc.

Well... I seem to be just dittoing Michael this morning on most of these threads. He's right on the money. The water in the hull will absolutely cause the symptoms you are describing in performance. Something is leaking that wasn't put back right. I'd almost guarantee it.
 
I got a question... Was this ski before you bought it run in saltwater?? Reason is that my RXP had a pin hole in the water exhaust and it put a lot of water into the hull. Just a thought..

As for and auto bailing pump.. I have an 600gph pump with an float arm for extra insurance as I do fish offshore with my ski.

The stainless steel J-pipe goes from the exhaust manifold to the waterbox, and yes it's the big round thingy that's strapped down with rubbery cords behind the exhaust side of the engine and it's encased in a black rubbery material (for more sound supression, I think).

I got my SeaSense automatic electric bilge pump from Academy Sports and Outdoors. It was like $29, has a very small footprint and a built-in mechanical float. Find a spot on the bottom of your hull back near the jet pump, rough the spot up with sandpaper then epoxy the plastic bilge pump base to the bottom of your hull (use 2 part liquid epoxy, 15 or 20 minute setup). Allow to dry well! Snap the bilge pump onto it and route the wires (there should be 3, 2 hot lines and a ground line) around the engine up to the battery. Using an inline fuse with a 20-25 amp fuse, connect the automatic hot line to the battery so it's in auto mode full time. Run the other manual hot line up to your glovebox and put a switch in the front of the glovebox (I used a small lighted rocker switch) and hook it up to the same inline fuse you ran the auto hot line to. The glove box come out of the hull btw it's just clipped in there. Get a 90 degree thru-hull fitting same size as the bilge pump discharge hose, mark and drill hole for it in the hull (mine is under the grab handle at the back of the seating area). Measure 3 times, drill just once make sure you'll be satisfied where you drill this hole and there is nothing behind it inside the hull that will conflict cause you don't get any do-overs here!!! Hook up the discharge hose to the thru-hull fitting. Test by using a waterhose to fill the hull with water and verify the automatice bilge pump kicks on and discharges water over the side! Should take about 3 hours start to finish.

Nope I'm in North Dakota, a long ways away from salt.
