My 1989, 85hp force outboard is not pumping water through the engine. I installed a new impeller after removing the lower unit for shift rod seal repair. Now water is not coming out the exhaust port. With the lower unit off, I even tried to put the water hose into the water tube and force water in. With and without the engine running. Nothing is going through. I'm sure the impeller is in correctly. Why or what is causing this. My Clymer Manuel does not show the route of the water after it leaves the water pump. Is there another mechanical part in there? Also, the shift rod bellow type seal for the shift rod is rotted away. I could not find one. Is there some place to get them? I have been told you have to buy a new shift rod and a new gear case cover with the new seal. I came up with a fix for this. I am trying it out now, will post it when I know it works. I would still like to find the original bellow type seal if possible. Thanks for your help

Re: Help!!!!help!!!

I swore mine was in correct, but I pulled it to check, and it was in wrong.

Here is what I read here and it worked perfect.

Put the key in the groove on the shaft.
Slide impeller over the key. This way you can tell for sure the key did not slip.
Put some grease or vasaline on the impeller blades.
Place cover on top of impeller, rotate shaft clockwise, while pressing cover down.
Wooohooo, it is in, and there is no doubt about the key and the direction.

Also, make sure the water level in the tub you use is up to the pump level. They do not self prime.
You should get water out of the two holes within a minute or two. A quicker way that I read, was to pull the t'stat out, but don't have anything behind the engine, including you.

I don't know about your other question.

Re: Help!!!!help!!!

There is nothing else in either the block or head to stop water. A broken thermostat will stop water but only to the head and even then, it has a small bleed hole so you should see something.

Water comes up the brass tube into the adapter plate where it makes a 90 degree turn and then goes into the block right below the terminal board. There is a hole in the block there (right next to the bottom of the exhaust cover plate) that was used for a bypass in older engines but I believe yours does not have the bypass. The hole is about 2 inches deep and blocked off at the bottom. If you do have the bypass, there will be a diamond shaped plate covering the hole. This was a pressure relief and shunted some water to the midleg when the thermostat was closed. Water is constantly circulating through the exhaust jacket and the blockand after circulating, dumps into the midleg. The thermostat only controls flow to the head. So with a hose attached to the tube, you should see water exiting the exhaust. However, you must clamp the hose to the tube--otherwise it will leak enough so that almost no water will get up to the block.

Were all the fins on the impeller present and complete? Sometimes one will break off and travel up into the block.

However, unless the entry hole into the block is completely blocked (unlikely since it is a square hole) even if a water passage was blocked, you should still see some water flow with a hose connected directly to the tube. So, try rodding out the tube. It is almost a straight shot right up into the adapter plate at the base of the block. And do not bother to try to remove the square headed pipe plug in the side of the adapter plate. It is either glued in or cast in and will not come out.

Where is the thermistat located?? I did not see or read anything in my Clymer manual. I have been using muffs for the water source, today I wiil try a tub. The muffs always worked in the past. The old impeller was cracked but complete. Pieces were not missing. Thanks Again

Re: Help!!!!help!!!

Thermostat is located near the top of the head inside the rectangular cover. Be careful--Two of the four bolts enter into the water passage and are almost always corroded in tight. Try not to snap them. When you do get them out, re-assemble with PLENTY of anti-seize. And the gasket will probably be destroyed. It is a simple one though and you can make one instead of waiting to order one.

Re: Help!!!!help!!!

I have had a Honda 45 overheat on the muffs due to the muffs being weather cracked and having lost spring tension from being left on the lower unit all the time.

Also, I had a tiny piece of impeller get lodged in the tube where it makes a 90* bend into the powerhead on the same engine- the powerhead had to be pulled to get it out. She would run fine off plane but try and get 'er up and she'd set the horn off every time and start steaming!

Just some things to keep in mind.:)

I found the thermistat in my manual on the power head disasembly page. Just a picture, no info. It looks like a spark plug. It dosnt look like it would stop the flow of water. Looks more like a sensor. Page 347 #50 in Clymer manual. Ill look this afternoon to see if I can reach it. Im in a wheelchair, so I can only reach so far. Thanks again for all the info.

Looking at the maual again, I looked closer and found the real thermostat. It is #54 on page 347 of the Clymer manual. It looks like an automobile thermostat. Are these available? If I remove it and try to flush the motor again, will that show me that it is the problem?

Re: Help!!!!help!!!

Do you have a clamp big enough to put around the muffs? Try that before surgery on the motor.
