Hi guys I was doing routine maintenance on my Chrysler yesterday changing out my impeller and when I got done with changing the impeller and went to put my LU back on the water tube that connects to the water pump houseing fell out. Could somebody please give me some info on how to re install my water tube in the correct way. Thanks guys!

I have not had it to happen but feel it slipped out of the bushing or Etc it was trapped in at the motor as on the impeller housing. I thought I could quickly spot a section view in Clymer or on line to verify this. Since I could not spot the section view you should easily see the fitting where the tube came from (with a flash light).

Get a flashlight look up there for the hole that it fell out of., put tube in this hole first. Have somebody hold it up there if you have to.
Here's the risk you don't get it back in the hole and the motor burns up,make sure the water tube connects on both top and water pump correctly.
At first start up make sure a water stream comes out indicator hole.

Thanks for the replys guys. I still haven't figured out how to get it back it the hole that you guys are talking about. Not even sure I'm putting the water tube back where it was. I managed to put the tube onto the Lowe unit and put the lower unit back on but I can't be sure that it went into the right place. I'm kinda scared to start the motor without knowing for sure. Any more advice of ideas would be very helpful. Does anybody know exactally where the tube leads to.

Did you look for the upper hole? IMO you should secure the tube in the top first. Does someone have a pic to show if the tube will guide itself into the power-head? Possibly the tube will not let the bottom fit if the top is not in place. I never looked up since it did not come out.

To be safe, I would double back and check the top fit with a camera and share it. Most of all when you fire-up in a barrel or lake you should have instant water or turn it off vs overheating your engine.

Do you have a friend or Etc with more experience that can help you? I had 4 Manuals and a camera showing my questions if I had needs on my 1[SUP]st[/SUP] jobs. LOL! A lot is not sounding good.

Good Luck!

Please don't start the motor,the water tube didn't go back in the hole, drop the LU, get a flashlight look up into where the water pickup tube goes,get on your back and look up in there for the hole,you got this,you can do this.
If you can take a picture up there, this forum will help you get it in the hole.

Please do not make any short cut by putting the tube back and hope/guess it got inplace.
To do this is very difficult and next time you pull the LU the tube will come down again!!!!!
The fit in the outlet from the impellerhousing will hold the tube and it will not stay in place in upper part.

The tube should fit in a rubber groumet at the top of the midleg and be connected to the engine block.
The rubber groumet also seal the water intake to the block.

To do: Remove the engine block from the midleg and the put the water tube back, Make sure the tube fits in the groumet and maybe put a little glue (super glue or some glue that handels rubber) to the tube.

Thanks guys. I found the hole to the power head , that the water tube goes into. My lower unit is made up of two parts. I'm still having a issue of getting it to go back into there. If I removed the second part do you guys think it would make it easier . And is there anything I should watch for while doing it. Sorry I'm asking so much but I'm new to outboards and really want to learn more about them

Are you saying you are working from the top of the leg extension between the Power head and Lower Unit.? It?s easier to connect the water tub to the lower unit if you work with the extension connected to the power head. Work just above the L-U to help verify connections.

If you are not working at the bottom, I can not visualize your processing as others. Do you have any local friends with boat maintenance experience? Plus, do you have a Manuel as a guide in this process. Both on site would have you Up & Going by now. ?Maybe?!!!

What I have done is pull the 4 bolts holding the lower unit on then it came down about a inch then I disconnected the shift linkage. Replaced the impeller then the copper looking tube fell out while putting the lu back on. The tube looks similar the the picture I'm posting. I think I can see the hole that it goes back on but it's being a pain to re connect to the hole.

The lower unit posted is all that came off my leg and extension. I had wiggle room to align the water tube that did not drop any IMO. If the tube has dropped or is not in place at the power head this could be a problem. Can you show a good close side view pic of your present issue? Hang In There But Call For HEEEELP!

The tube you poster shows quite a bit should seat in the head.

Well I did like you guys said, took a flashlight found the hole and connected it. I think!!! Not 100% sure I had it in the right spot. Put everything back together and no water came out when I started it. Before I ever did the impeller changed I started the motor and no water came out either. That was before I ever started to do any work to the engine. It fired up and no water came out. Could I have a water pump issue. Or does the motor haft to be in gear before water will shoot out the little water hole. All I had come out was a bit of smoke

There isn't a little water hole on this engine. The water comes out the exhaust. If the water pump is working, the clear plastic tube that goes from the thermostat on the head to the engine block will fill with water quickly after the engine is running

IF? the tube is in the hole?
​The water and exhaust comes out the snout.
Some "might" come out the mid section.
How are you supplying water to it?
The older ones need a special muff.
The big ones don't always work right?
If using a bucket, the lower unit needs to be 3-4in. above the water pump.
These aren't self priming.
Since Windows 10 I can't post pics.
If you want a pic of the right muff send me a PM with an e-mail.
If the lower unit is off?? Hook a hose to the tube and see if the water flows through the head.
Anybody have a link to parts diagrams for the older Chryslers??
Most only have stuff for the 74 and up.
I found a site that SELLS the diagrams and factory manuals but I don't need to buy. ​Hurrikains Chrysler outboard.

The 45 hp didn't change much from 1965 onward. Minor differences like the throttle linkages for the remote cable connections, but the water pump and cooling system were virtually identical probably up until the 1990s at least.

For testing, it's better to run these motors in a 50 gallon barrel.

Is this your first impeller change, if so you-tube explains it perfectly, watch videos until you feel comfortable
Borrow or buy a Inferred temp gauge gun point it at the top of the head for the current temp , so you don't overheat,and burn up the motor
