2001 Seadoo Sportster LE. Just got it!

[Sportster-2001-951C-Stock]

- The bearing journal of the damaged needle bearing has scratches because the needles were seized and the cage was spinning in the journal.

Edit: Need to find a way to clean the housing, brass particles everywhere.

Are planning to shower with your pump, too?

I guess the needle bearing journal didn't spin inside the housing, so no damage was done to the housing aside from the thrust washer bearing seized and spun the thrust washer.

Are you going to install two new driveshaft bumpers? Did you remove the driveshaft from the PTO already?

Plus I have a simple way to check is all the seals are air tight. 1/4 vinyl line with a syringe . But don't push too hard.

You have to test while empty (seals are not covered by lubricant) measure the pressure and record the drop, I think. 3min at 5psi for crankcase and 10min at 10psi for jet pump.

Sorry I meant the cage was spinning in side the housing because the needles are all seized too. So the brass housing does have scratches. But I checked with a steel straight, cannot tell there is real material loss or very little.

The rubber bumper is still on the shaft. I didn't remove drive shaft.

I definitely will check the jet pump this time. Glad I didn't push on another 5 minutes of wave jumping, which I believe this seadoo will do. Otherwise I think the housing would be long gone.

LOL. Hot water to get the oil off the housing so that the metal piece can come out. Will use hand soap this time. And test on the surface first.
Then I can use my pressure washer to do around of blast?
Then air compressor?

 

[Sportster-2001-951C-Stock]

Yep, I would use the pressure washer and compressed air. Soap like dish soap with some kind of round brush will help to wash away oil and grime if necessary.

Is brass going to rust with the same condition put on my cylinder wall?

Everyone (especially our chihuahua) wants a smooth ride in my boat, no aggressive wave jumping for us.

Somewhere I saw a sportster photo at the beach jumping ocean waves. This photo showed the boat with at least 10ft of air.

 

[Bonmotwang]

Now I kind of understand how you can abuse a seadoo, because it just does if you ask, until pieces start to fly ... ...

 

[Sportster-2001-951C-Stock]

LOL, especially a 951 jetski!

I had a chihuahua, very nice pal. But my son seemed to have asthma when he was 2. We gave her to a friend with doctor's suggestion.

Shouldn't do too many jumps. I guess this is one kind of abuse. LoL. The hull has it limit too. :-D

Wow 10 feet. A question here, do I need to bring the throttle down when the pump is in the air.
Last weekend I did hear the engine sounded different (not strange) when the pump is in the air. I didn't look at the RPM, must be very high?

 

[Sportster-2001-951C-Stock]

Yes, you should bring the throttle down if you can but it will hit the rev limit at 7200 RPM. and bounce off that.

I think if you are out of water for just a moment you cannot coordinate the throttle for limiting the revs but if you jump 10ft or more (I'm sure this boat was more than 10ft actually, maybe 20ft) you might have time to throttle down and avoid running against the rev limiter (it's not exactly good to run against the rev limiter if possible).

I think if you do throttle back then when you hit water the boat might stop, instead of continuing on.

Check youtube, there are lots of small seadoo boats jumping ocean waves.

They will stop very suddenly if you chop the throttle in the air, stay in it and let the rev limiter do it's job for a couple seconds or you might take one heck of a following sea over the back of the boat in the right conditions.

There was a method to the madness of sealing up that engine bay hatch as well as they did.

I think you heard the water clearing out of the exhaust, the exhaust note changed I suspect?

Yes, maybe you will discover the meaning of a following sea, I have no idea really b/c I've never jumped my boat. I think it's common practice to throttle back but of course cannot say for sure as I haven't tried this stunt.

Agreed, they did a great job of sealing up the engine bay hatch, a feature I like very much for some reason.

It's bronze, slightly different alloy and even more corrosion resistant. Your cylinders are iron, corrosion to iron oxide will happen in the presence of oxygen. No, water won't hurt bronze (bronze is the best thru-hull fitting material, IMO) but I wouldn't give it corrosive peroxide or acids, dish soap is mild and will break down the oil so you can wash the muck away.

I have briefly kissed the limiter a few times in the air but wasn't anywhere near WOT when I launched it, first time I did it I dropped the throttle abruptly because the wife was already letting me know she wasn't impressed at all and subsequently that self bailing deck feature came in handy. ~Like 20 gallons handy, lol!

Well, I have experienced a couple of times of "front lake", on the plane at 30mph, then someone started screaming "stop", I cut the speed to idle. Boat slowed right down, and blow dropped right down, and 3 seconds later, yes, 20 gallons of water came right in over the bow. LoL

I've taken water over the bow too and it's not a big deal with the self bailing. A following sea comes over the stern when the boat stops too suddenly. I get plenty of boats in the shop from this maneuver, not sure how they're doing it though.

Thanks. I guess less jumping is better
Won't follow big boats anymore ...

Yea, no supercharger clutch washers here. -Drive it like you stole it! Unless your wife threatens you with cold meals for the remainder of the boating season, in which case I'm ok with keeping the hull in the water all the time.

I seriously can't imagine being 8' in the air with one though, I was maybe two feet for three seconds and got read the riot act.

"I was maybe two feet for three seconds and got read the riot act. "
Yeah, I can imagine that.
