Ok so i have this 98 GTS was ready to drop in water for test run today when i started it up and heard sloppy noise from the rear. Shut it down started my quest to find the problem after removal of reverse unit and steering i find the issue. the cone for the jet pump seemed loose? Well its was tight but when i moved it around it had play and moved the shaft and prop. After removal of the cone i notice it seems look like metal has seperated from the housing?
So i have a extra jet pump from a 95 HX i parted out so i tore in to that to see if it would work well that housing where the cone attaches 3 8mm bolts is metal not plastic and metal like the 98 gts. :banghead:

Now what would you do to remedy the situation or what are the correct steps to fix this? This is obviously not right.

If you need photos to better describe let me know i will snap ones

thanks
 
I hate to tell you this after all the trouble you went to. Play in the drive is normal, probably about 1/8". This is known as the "SeaDoo rattle".

It will go away under a load. If it bothers you there is an anti-rattle kit is available, it's new pump cone with a spring with a teflon pad. It's not very effective and I consider it a waste of money. What I do is just set the idle to about 1600-1650rpm.

thank you lou

but the other one (95hx pump) has no play and on my other 98 gts there is no play as well that is why i'm confused
 
I just checked your ski should have the anti-rattle kit. Maybe it's missing. It really doesn't do anything anyway. I wouldn't worry about it.

It's part 47 & 48 on the parts diagram.

BTW it would be a big help if you would list your ski or ski's in your profile and well as a more specific location. If the thread gets very long it can be a hassle to go back to the first post to see what ski you have. Also your location can tell us how much use your ski gets as well if its fresh water or salt water use.

yes lou it does have the kit however with the cone attached i have side to side play that is what i am worried about. As far as the skis go i just picked them up and have been wrenching on them getting them ready for the water. Then this noise developed today when i went to make sure she started before taking to the ramp. Upon further inspection it looks as though the 95 hx housing is the same but i need to remove the nut and do not want to buy the special tool. Also does the prop shaft nut spin clockwise or counter? before i got tighten it up and not know which is which
thanks
 
O.K., I guess I didn't understand your question. If you have side to side play most likely the shaft bearings.

ok i guess bearings might be in order but i have a question when i remove the pump house and the shaft comes out from PTO how do i remove the shaft from the pump housing in order to take the prop off.
 
Once you have removed the pump, turn it upside down, and clamp the end in a bench vise. Place the impeller removal tool in the impeller and remove (turn left) with a breaker bar and a socket (3/4" I think). Here's a thread on replacing the wear ring which should give you the basics. Depending on the condition of the wear ring you might want to replace it also.

I've replaced bearings using various size sockets to drive them in, but it's not easy. Dr Honda has a set of tools for removing and pressing in the new bearings. PM him if you are interested.

Lou
 
So good news the HX pump housing is the same and fits perfect. Also you can remove wear ring without taking impellar off just took a little longer hope to put ski in the water a little later for a test run.

Differences in the two housing is its metal as the newer 98 one is plastic so its a little heavier no big deal it seems better built then the plastic one
 
Listen to your motor, or ski. That is in your Owners Manual.
What its saying is "grease me, Grease me" with Marine grease GNLI #2 rated. (usual method is a 14 oz grease gun)

That said, pump up your two zerk fitting on the drive. One zerk is on the PTO, keeps pressure on the driveshaft bumpers to silence the end-play and lubricate the shaft's Splines, without those the twisting of the hull when underway would damage the engine. One is on your Carrier Bearring, it keeps water out of hull and lubricates the needle bearings inside that roll on the driveshaft.

everything is greased up but wouldn't you know i go to start it and it wont crank go figure it cranked perfect yesterday but after the install of new wear ring and replacing the pump with the other because the bearings were bad it won't turn over. I am hoping battery just went dead so it is on charge now i will try again later. :banghead:
 
update pulled the jet pump ski fired right up put it back and it wont crank fast it turns but i guess it is binding. now to figure out how to align it. I did just put new motor mounts in and it ran after that. Any tricks on how to align it from here. I made sure the jet pump spun free which it does and it seems align up perfectly
 
i should rephrase it ran after new mount install with the pump with bad pump bearings installed. I guess i will loosen the mounts tomorrow and try a realign.
 
I was thinking if we had an old pump housing with the bearings and a piece of steel or aluminum the same dimensions as a drive shaft except longer. Would that work?
 
update and hoping any possible suggestions

I loosened the motor mounts bump the starter and still same scenario.

next i took the plugs out and tried turning it over it cranks perfect. Put the plugs back in and same deal. it tries to crank but just can't kick it fast enough and after a few tries the battery seems dead so it is on charge again.

now i have tried a brand new battery and still nothing. After the battery seems dead i try it in my other ski and it cranks over perfect.

all possible scenarios to remedy this would be great

- we've all forgotten to turn the fuel selector back on after working on the ski, so just something to doublecheck
- "tried a brand new battery and still nothing" - do you mean it cranks good with the new battery but won't start, or it cranks slow with the "new" battery too? have you checked for spark at the plugs? might want to have the "new" battery tested, some are bad out of the box.

- Fuel is on
- Batteries are good both fire the other ski right up
- cranking sounds like this "VRRRRRRRRRRRRRUMP VRRRRRRRRRRRRRUMP" not VRRR VRRR VRRR VRRR VRRR to running like it used to before new jet pump with good bearing and wear ring

- ski will crank all day with plugs out and jet pump installed also will crank all day with jet pump off and plugs installed

- then I assume with the pump in and the plugs out, you are able to turn the engine by hand by turning the driveshaft?
- from your original post, it looks like it was starting fine before you took the pump off and If you can turn it by hand, that should rule out the pump binding. you didn't say if you are getting good spark at the plugs. holding the plug wire boot, hold the firing end of the plug next to the engine and look for spark while cranking, ground the other plug wire on the grounding lug. check both plugs.
- try removing the boots and trim back the wires 1/4" and reinstall boots with zipties
- test the voltage across the battery while you are cranking the engine with the plugs in. a good battery will read at least 10.6 volts
- replace the plugs?
 
i can not turn the engine by hand with plugs out

have not checked spark reason is ski will start with pump off

just confused as to why ski will bind when plugs are in and when plugs are ski cranks all day so i am unsure of alignment but all seems straight
 
ok i loosen the pump an it spins perfect

I just relized i put he newer the newer style jet pump cap on this pump maybe that is binding it up

if you cannot turn the driveshaft fairly easily by hand with the plugs out then something is bound up. you may have gotten something out of alignment. try to turn it gently with a pipe wrench, maybe you just arent getting a good grip on it, but I wouldn't try to force it with the wrench.

does the pump turn freely when it is out of the ski?

re spark check, if you put one plug wire on the grounding lug and are holding the other plug in your hand then the ski can not possibly start.
