SERIOUS WATER PUMP PROBLEM

[pursuit2460]

Where do I start. Well I started by removing all the bolts that hold up the lower unit. The lower unit only dropped about 1/4 to 1/2 inch it would not go down any more than that. I started putting some presure on it with a crow bar. While I was putting little presure on it and trying every and anything to get the lower unit to drop I saw that the water pump housing was flexing up everytime I andded pressure to the lower unit. So I decided to brake the housing. After I did that the lower unit dropped. I cut the blades of the impeller to make it easier to handle and to get it out of the metal housing it spins in. No matter what I tried the impeller would not come off. It would only move up or down about 1/4 inch. Finally decided to cut the impeller in half to get it out. Now heres the problem the new impeller will not go on. The manual says that the cam lock I think thats what its called the little white piece that locks the impeller to the shaft. Anyways it says that the sharp edge must be the leading edge with the shft turning clockwise looking at the shaft from the top. The impeller can only go on one way and it wont. The impeller has two different sides one side is open the other side has like alittle lip on where the cam lock is suppose to slide though. With the water pump installed on the lower unit that little lip wont let the cam lock slide though. The only way that the cam lock looks like it will slide in is by fliping the impeller and the cam lock. Any adivce has anyone had this problem. Should I filp the parts what do I do. Its a 93 Johnson 225 and the water pump kit was a 5001594 THANKS

If I knew what your motor is. I would see if its in one of the manuals I have. <br /> Until then , I have no idea. Maybe someone else can help you without knowing, what you motor is.<br /> KYHunter

Re: SERIOUS WATER PUMP PROBLEM

I have a manual that goes up to 1990. The water pumps in it are straight forward. I'm sure someone with experience , on your engine will reply.<br /> Sorry, I couldn't help.<br /> KYHunter

Re: SERIOUS WATER PUMP PROBLEM

It will only go one way. Maybe you are misreading or misinterpreting the manual. Put it on howeevr you can make it go on. I assure you it will be right. The thick part of the halfmoon camlock must go into the deep part of the cut in the impellor.

Re: SERIOUS WATER PUMP PROBLEM

Well the way that it will fit will put presure on the thick front part of the cam lock were if I could put it the other way it would put the presure evenly on top of the cam lock. When I had the enginge rebuilt thats how they put it the manual says the same and the OEM diagram that came with the impeller shows it like that hope someone has an answer on this.

Okay, I think I found your problem. The camlock goes on first and you slide the impellor down over it. Not impellor first and slip the cam lock into the impellor from the top.

Re: SERIOUS WATER PUMP PROBLEM

What Walker said. Put a dab of grease on the key to hold it to the shaft and then slide the impeller housing, with the impeller installed inside it, down onto the shaft and key. A little tricky, but it will go....

Re: SERIOUS WATER PUMP PROBLEM

I know that the camlock has to be on the shaft while you slide the the lower unit in place but if you do it the way the manual says that lip on the impeller wont let it slide in. I would have to put the cam lock and the impeller opposite of what the manual says.

Re: SERIOUS WATER PUMP PROBLEM

Then put it on that way. It will work fine.<br />I have to think your are mis-understanding the manual or the manual has a mis-print. I've never seen a backwards impellor

Re: SERIOUS WATER PUMP PROBLEM

Try it this way. Install the impeller and key onto the driveshaft first, like thisIgnore the guide pins, as this is a different model)<br /><br />

<br /><br />Then, install the impeller housing. With one hand, turn driveshaft CLOCKWISE (as you look down from <br />top) and with other hand push down housing onto impeller. Keep turning drive shaft until the housing is all the way down. Like this:<br /><br />

<br /><br />Hope this clears it up. Don't forget the key...

Re: SERIOUS WATER PUMP PROBLEM

It would be easy if my shft came out like the picture u posted but my shaft stayed in the motor. Does it have to come out and if so how is it suppose to come out. If you read my 1st post the shaft didnt want to come out thats I thought that was supose to stay in. If I can get the shaft to come out it would be a breeze to do. THANKS

Re: SERIOUS WATER PUMP PROBLEM

are you saying your drive shaft is still int the motor?????<br /><br />then how did you get the lu off???<br /><br />the drive shaft is conected to the gearcase.<br /> you must have broken something ????<br /><br />if thats the case i would look out for a new lower unit and drive shaft if you can get the shaft out of the crank.<br /><br />good luck <br />i hope i misunderstood you.

Re: SERIOUS WATER PUMP PROBLEM

I just changed out my impeller. You need to release the lower unit by unscrewing the shifter pin. The shifter pin in my 1984 rude is under the carburators. An easy way to find it is to move your shifter back and forth. You will then see that there is a pin holding the shifting rod to the shifter. Tis rod runs down into your lower unit. I had to take out my starter to get to the shifter pin. Hope this helped!<br />Kris

Re: SERIOUS WATER PUMP PROBLEM

I think im in trouble. Reeldutch are you saying that the drive shaft should not come out of the lower unit by it self. Is it held in the lower unit with something. Anyways if thats the case then Im in trouble because I was able to break the water pump housing so that the lower unit would drop. Then had to work on loosing up the shaft from the motor and was able to get it out. I just finished assembling it. Another question is there supose to be water coming out from in between the lower unit and where it bolts up to. Thanks for all your responces they have been very helpful. Dont know of any trust worthy mech. and to do I bad job I prefer to do it my self and learn in the process. Thanks again

Yes, some water from the seam is normal...

Re: SERIOUS WATER PUMP PROBLEM

You could have prevented prevented turning a lower unit into trash with a visit to your local library. They generally have service manuals for cars as well as outboards and I/O's. If they don't, buy one right here on iBoats, the dealer, e-bay or wherever before you do any more damage.

Re: SERIOUS WATER PUMP PROBLEM

I have the manual but it isnt exactly clear and persise on anything its a Clymer manual. I was able to get the shaft out of the motor and put it back together. But now Im reading the post that reeldutch wrote and he said that the shaft should not come out of the lower unit. I tried looking in the manual but its not specific like I said so I was asking in here for advice. So is the drive shaft that comes from the motor with drive the water pump with slides into the lowewr unit supose to come out with out having to disassemble the lower unit. THANKS

Re: SERIOUS WATER PUMP PROBLEM

well the drive shaft can come out of the lu but i have no cleu how you got it out without tearing down the gearcase.<br />well you saved your powerhead by getting the drive shaft out.<br /><br />i didnt say you trashed your lu but shurely you most have caused some damage.<br />i suggest take it to a repair shop and let them take a look.<br />new gearcases dont come cheap.<br /><br />next time do yourself a favor and ask questions before you tear something down your not sure off.<br /><br />we are all happy to help you out.<br /><br />reeldutch
