So I was out today taking my family sea dooing, was using it the weekend prior not a problem what so ever.
Engine still looks mint and no weird smells.

I went out with 2 adult men, and pulling another adult male on the tube..

we got out about 3 minutes, put on some speed then I seen white smoke flowing out the back, turned it off, went to turn it back on and it started making some serious metallic screeching bad noises...

turned it on a couple more times and it just got worse and worse so got someone to tow me in

anyone have any idea as to where I should start looking?

i have only owned it for 2 months, fresh in the scene, but am mechanically inclined..
any help would be great
 
From what you're saying I'm guessing it's the pump bearings. I would start by removing the pump, see if the pump has lubrication and if the bearings spin freely.

How do I even start to removing that? Do you have any links to how to start this? Cause I'm not even sure what the pump part of the engine is lol! Under the seat? Or out the back?

Either way it's 10 pm so i'll be starting tomorrow.

It sounded like, the engine would start, then a split second later there would be some metal on metal type noise from probably the bottom towards the rear.

This happened at about 11 am so my mind could be off, and I'm also a little scared to try starting it again.. I did like 3 times and it just got worse lol
 
Yea... The smoke is what scares me as well...
A bunch just started dumping out the back, then my buddy gunned it, i tapped him, but before we know it, metal noise, and it shut off (not sure if by him or what)

Once he gunned it tho, it went away only to be a million times worse in a few seconds
 
Pump is on the back held on with 4 bolts....make sure to unhook the steering cable and reverse cable too.
 
so i got it all off... i couldnt get my hand in to spin the impeller, so i used a wrench, it moves pretty easily...

You only have the steering nozzle off in that pic. There are four more nuts on studs that hold your pump housing on. Remove them and wiggle and tug on that pump housing until it separates and slides off the ski. The drive shaft will drop out of the impeller and clunk against the opening of the hull, just a heads up.

The impeller should spin freely by hand and coast to a stop. I would pull the impeller (special tool needed) and look at the bearings and shaft and the oil that comes out of the nose cone. Since the pump is off, I would take a look at the drive shaft as well. Look at the condition of the wear ring while you have it in your hand, too. If the pump was binding up, you will want to verify that all the splines on the shaft and in the pto are ok.

Pull the spark plugs, put the boots on the ground lugs by the battery and first, try to roll the crank by turning the pto. This is just for peace of mind. If it moves easily and without noises your motor should be ok. If you have a compression gauge ($20 from a car parts store), I would check that for a little more peace of mind.

Ok so, I just got the pump off,

pretty sure the wear ring is done.

this rubber gromet or whatever came off when i pulled it off

the axel didnt come with it, and when i spin it with my hand, there is some serious grind noise coming off of it, and at 3000 rpm, could quite possibly be what i was hearing.

that grate at the bottom also looks like it was smashed, and welded back on? a little bent + hooptied out at the seam
 
Pictures one and two look normal, the impeller has some serious wear and dings but nothing the would cause the noise and white smoke. I'm not sure what I'm looking at in picture three. So are you able to turn the impeller by hand? Remove the cone and see what the gear oil looks like. Post a picture with the cone off.

Click to expand...


So the wearing ring is still good?
Picture 3 is just the axel that the pump spins from. into the engine, when i spin that with my hand there is some serious grinding going on.

I'm able to turn everything by hand
 
I took the nose cone off, jsut full of oil and spilt everywhere... do i need to fill it back up with a special oil before i put back together or?

The pump looks O.K., not particularly good news, I was thinking it was the pump and not your motor.

The pump uses 75w90 GL5 synthetic gear oil, I use Mobil 1.

You say you can turn the drive shaft by hand, you shouldn't be able to, unless you have removed the spark plugs, and even the it won't be easy. Does the drive shaft seem to be loose, I think the next step would be to remove the flywheel cover and see if the drive shaft turns without the motor turning.

Lou
 
I didn't remove the spark plugs.
The shaft I took a picture of (3rd pic you said you didnt know what it was) i can move is 1 handed with no issues, and lots of grinding noise.

Pretty loose, I can push and pull it maybe a half inch back and forth. When I pull it outwards, I cant spin it any more, when I push it back in, I can spin it completely and hear grinding.

How do I remove the flywhere cover?
 
This actually maybe good news. Remove the flywheel guard part no. 6, by removing the two wing nuts part no. 8. If the drive shaft turns without the flywheel turning you probably have a striped drive shaft.

You probably need to go ahead and download a service manual, you can get one from this site if you join as a premium member, or you can just google for one.

Lou
 
Yeah, I think your pto (part 22) will be shot, too. This drive system looks kind of like mine. After removing the drive shaft get a few photos looking into the hole where the shaft goes into the pto while shining a flashlight on it. Then you can see if the splines are ok before trying to pull it off.

I tore my wear ring to pieces, stripped the drive shaft and the pto. I still am not convinced that seaweed was the cause, but barring that I have no idea what happened.

Thanks for all the help guys, its much appreciated.. I think I found the problem, and yea, either sea weed, or is it possible that we just had to much weight? And stressed out this metal thing too much it shattered.

When I finally got the cover off (does anyone know how to remove to air filter thing without busting the tabs?) This is how it looked:

After struggling with the boot for a bit I finally got it out and found this metal thing that i said before shattered into numerous peices.. pretty sure i got it all out of the hull, dont want any of that touching the motor now lol

I put the axel back into the engine to see if it turned, it feels stripped right apart but i found some groves and it wont spin at all, if i pull it out tho itll go back to spinning. and all the notches inside the female end on the motor feel like they are all good still so no problem there hopefully :)

So I'm pretty sure I have a bunch of parts to order here...
I live in ontario and dont think I have a sea doo dealer anywhere near me, where would be the best place to order oem parts? that site you gave me?
 
I'm sure Minnetonka4me has the parts you'll need. He's the go to guy when I need parts, just shoot him a pm.
