Driveshaft backing out of jet pump pt2

I posted a couple days ago on this issue. Just started digging back into the ski. The main thing I wondering about is this video I got. Took off the pump and started manipulating the driveshaft by hand to get a feel for how much it’s able to move. Is this amount of movement normal? If you haven’t already seen my other post I would recommend looking at that to get some context on the issue. When the driveshaft goes all the way forwards, that’s obviously when the grinding occurs and carbon seal is no longer doing its job. When I move the driveshaft by hand, it feels like it moves forward slightly and then gives way the rest of the way. My brother also said that something didn’t feel right about the pto bearing. So my main suspect at this point is that. It seems like when the driveshaft is pulled all the way back that there is enough of the splines the engage with the impeller. So the engine alignment does concern me as much. Any advice is greatly appreciated.

When we bought this, I asked specifically "Does that plastic floor get hot?" The reply was "Oh no. Not at all. It stays nice and cool." My ass. It will now though.

We couldn't believe how hot this floor got in the sun. We had to wear shoes out on the water. Thank goodness for SeaDek. It matches too thankfully. Now to put the snaps in. If the flood waters receed, we'll be ready to try it again this season.

2027 Model Update Thoughts

New 2027 RXT/RXP get a few upgrades over the 2026

New orange color scheme and limited edition Senna yellow

350HP engine (tune, beefed up crank bolts and bigger compressor wheel)

Revised ride plate to angle bow up and reworked stator on jet pump

Price increase of around $2,000 vs. 2026.

How much real world improvement do you think all these changes are going to translate to?

787 not starting? due to oil?

so i have a 787, i bought it with a locked motor, a bolt fell down the carb throat and it pinned the bolt against the crankcase, it didn't split it at all tho. i pulled the engine, tore it down, and then i removed the bolt it spun free after that, i replaced the battery and starter and it spun freely, i still had to tune it, and when i did, it ran, after that, there were air in the gas lines, i pulled the fuel filter, new gasket, cleaned it, and it fixed my issue, along with all new fuel line clamps. the engine is brand new 2 hours on it from the prev owner, so i also ran 50:1 in the gas premix along with the oil pump, good idea i found out, as the prev owner didn't hook up the coupler for the oil pump, once i got it hooked up and the coupler installed, and got the old gas out and brand new rec gas in, new plugs, and carbs and oil pump all in factory spec. it still wont start, seems like its flooded with oil, so i pulled the plugs and fired her for a few min, until all the oil i could get was out, but it still wont start. it will crank, catch, the puff smoke out the exhaust then die. anybody know my issue, is there anything i need to do, i use NGK solid cap plugs, i use BR8ES plugs, brand new, the plugs seem wet, but not entirely oily, low speed idle is 1 and 1/4 out, high speed screw is flush, and the idle screw is flush then 1 1/4 turn in, and oil pump is lined up to its idle tick perfect. any advice? its got strong spark, new starter xps 2t pwc oil, fresh rec gas, cleaned carbs with all new gaskets, new battery, all new top end and bottem end gaskets, new exhaust gaskets, and new rotary disc, any help would be greatly appreaciated. also i got the ski for 700 so not too bad of a deal. TIA it has 152 psi and 151 psi of comp in the cylinders, and strong spark!

2009 GTI 155 SE

Hello!

I'm in the process of trying to find an entry level unit for our small lake. I've got kids that are just coming into the age when they can legally ride, and I have tooled about on my friends units some, but the one I've ridden is mostly an older 1998 2 stroke, yellow and white. Not sure the model.

I have a 2009 GTI 155 SE lined up for $4000 Canadian with a trailer from a known source. It has a ripped seam on the back but it seems like I can swap that out.

Otherwise it runs well. Has 198 hours on it. Seems to check the boxes that I can bop around the lake with the kids, put them on it to learn, but also take longer trips with our friend group.

Seems like a good deal?

Pre order ??

Hey group, I sent in my pre-order for the RXTX Gulf Stream in blue, but I wanted to ask how pre-orders typically work. I’m from Michigan, and knowing that the boating season is almost over, I would think they wouldn’t deliver the new models until early next year. Or are the dealerships trying to get a quick sale on 27 models so they can expedite shipping??

two stroke doesn't want to idle

Hi guys,

Recently picked up this 2000 GTI. Had it running great, did plugs recently too.

On my last outing, it decided it didn't want to idle anymore. Just stalls out if I go to idle. It still runs fine under power, but when I let off the throttle it just ends up dying.

It may be running slightly underpowered when I am riding too, however I may be making that part up as I'm looking for symptoms.

A few days ago I was out and I had done quite a bit of idling, is there a chance I fouled the new plugs?

Any thoughts would be great. Thank you!

Grab bar pole mounts

Wanted an option to take the ski out fishing without having to load up all of the gear. Now, a pole and a few pieces of tackle is all I need to take with me.

Spark x 1000ace tuning potential

The new spark x 1000ace is 110hp, will there be a flash aftermarket to unlock 120-140hp? Just in theory? Wondering if I should buy the X or just tune my spark trixx?

Seadoo Recall

Anyone have the recall repaired on the oil leak on the GTX300? Had a dealer try to fix it twice and it is still leaking. The second time they have it back saying it was fixed we ran it on the water for few hours and came back and oil level was low and unit was leaking again. I’m reading that maybe they did do it right or maybe the threads are bad. I also reading that if they over tightened it they could have cracked the engine. Very concerned . Thoughts?

95 gtx pump bearing

I changed the pump bearings and noticed that while putting the prop nut/bolt on, if i tightened too much, the prop couldnt spin. So i backed it off a little and installed the pump. Now its not starting and is very hard to turn the flywheel by hand. Is it possible that its tightening itself? It has a needle thrust flat bearing on the back of the impeller. What should i do/check? The battery is low so im charging but hars to turn by hand.

How Did I Do?

Just picked up a 2019 Sea-Doo Wake 155 with ~164 hours for $6,800. One owner, always maintained. How’d I do? Am I cooked? 😂

First-time jet ski owner, so hit me with all the tips, tricks, must-have accessories, maintenance advice, and things I should watch out for.

Anything you wish you knew before owning one? What should I check/replace right away?

Appreciate any advice! 🤙

97 seadoo gtx 787. Help please

I have a 1997 Sea-Doo GTX 787 that starts and idles great, but when I take off, it has very little power and won’t go much over 5,000 RPM. The weird part is that if I hit a wave, it will suddenly come alive and have full power. It will take off, run around 60 MPH, and reach roughly 6,500 RPM. It runs perfectly like that until I let off the throttle. Once I slow down, the power is gone again and it goes back to not wanting to get over 5,000 RPM.

Has anyone experienced this before or have any suggestions on where I should start troubleshooting? Any help would be greatly appreciated!
