1993/94 200 Johnson Ocean Runner water tube?

[rost495]

Never had a motor this big. Comes across as a 93, but serial number search shows 94....

Anyway bought it a few years back, and due to family issues it sat.

Started it yesterday, almost instantly. I was amazed. But no pee hole on a big engine? I don't see one. Need to know how I know if its impeller is working while runnign it.

Hooked direct to the hose fitting. Not muffs.

I have a water pressure gauge, not hooked up yet, but will do and still trying to figure out how to get sensors for head temps into the engine.

But the pee issue is bothering me. I'm attempting to have the boat water ready for a test 1JAN08.

Help appreciated.

If it has been sitting, dont run it any longer until you service the water pump and change the impeller, the rubber is likely shot. While the lower unit is down I would run compressed air up and down the water line to where the thermostats are located, to ensure that the water line is not blocked. Might as well change the t stats while they are out anyways, with new gaskets. What is the model number so we can figure out the year for you? It definately has a tell tale, it is either not pumping water or the tell tale line is clogged with a spiders nest or debris. Clean out the nipple on the cowl and the rubber water line that feeds it. Also ensure that the water intake area is clean of debris.

Will get the numbers this evening when I come back from the barn and soldering wires in....

I've got the impeller kit here. Thats next on the list now that we know it starts.
Just didn't want a new one sitting in there unused for a year or more....

I just fail to see where it would stream water from, thats what boggles my mind. My 15 and 25s have easy to find holes and you can see it streaming from them. I find NO holes up top that would indicate a stream of water out above water level?

thanks for the help!!!

Don't use the hose fitting while the engine is running except at low idle with no load. That is for flushing, not cooling. Use muffs on the water intake for more rigorous running and testing. See SB 2238.

Your tell-tale should exit near the starboard rear corner of the lower cowl/cover/belly pan. The water source is a fitting on the adapter plate, near the outlet, starboard rear.

BTW, the model number that you posted in your earlier thread, J200CXERK, is for 1994 model year:

I don't know if the setup on a 200 is the same as my 94 175 or not, but on my 175 the tell tale is in the plug that you remove to connect the hose to the flush port. My owners manual says that you can run the engine with the hose attached to the flushing port. It says that the motor cannot be above idle speed and the motor has to be verticle, not tilted. I have always run mine for a few moments while flushing, just in case there is some salt water trapped in the pump.

There are 2 ports by the hose attachment. Was not sure of what they are. One either side.

Nothing coming from either.

Just dug up a book on the motor will look further!

How much water comes out of your ports? And does it come out with the hose on or only when in water like a lake etc...?

I believe the 175 and 200 are very similar IIRC.

Re: 1993/94 200 Johnson Ocean Runner water tube?

I believe those 2 ports are exhaust relief ports. Did you look at the plug you removed to hook up the hose ? It should have a piece in the center that you can rotate so that you can direct the tell tale stream off to the side so that you can see it from forward in the boat. You will not see a tell tale with a hose hooked to the flushing port because you have removed the plug. You need to be in the water or be using muffs.

Re: 1993/94 200 Johnson Ocean Runner water tube?

Makes much more sense, IE you can run the motor with a hose, even with a bad impeller since the water pressure does the work, and no place to pee from.

Yes I noticed what I thought was a hole, now it makes MUCH more sense.

Will be a few weeks till we get to launching it for a test, assuming that I get allt the titles swapped etc... there are title issues on the trailer and motor that will be just another hoop to jump through.

Thanks, Jeff

As I mentioned, my manual says that if you run the engine with a hose connected to the flushing port, do not run the engine above a slow idle in neutral. The water volume through the port is not sufficient to cool the engine above idle.
I installed a new water pump a few months ago and I have 18 PSI at 3500 RPM and 20 at 4500. I did not notice the pressure at idle, but there is a very strong stream from the tell tale at idle.

Water cooling system for that motor.
