1989ish Not "peeing" but running cool...

Hey guys.. Im new here, I just recently purchsed my first boat, a 1987 20ft proline cc with a 225 evinrude vro. I do not know what year it is. It appears that someone has removed the tag and numbers and I cant find a model number anywhere on this thing. Its gotta be late 80's early 90's though.. its got dark blue paint and vents on the cowling if that tells you anything.

When i brought the boat home and put the motor on the water hose the "pee" stream seemed weak to me, just not very much pressure at all. Also the port side head was noticeably hotter to the touch than the starboard side. So i bought a water pump impeller and changed it out. I dont belive there was anything wrong with the one that was in there ,it looked almost brand new. And after swapping it out the "pee" stream didnt really get any better. I pulled the Thermostats and blew out all the rubber hoses to clear any blockage. I have no temp or pressure gauge and Im not sure if this thing has a tempature alarm or not but its never gone off.

Anyways i put it in the lake and ran it and it did great. Got it home and put it back on the hose and running it in the lake must have cleared out the cooling system because now both heads feel about the same temp, luke warm is a good way to explain it. But it still didnt pee very hard..

So this past weekend I took it out to the gulf for a insore fishing trip. The motor did great all day untill I was coming in and noticed there was no water coming out the pee hole. I did get up in some shallow water and churned up some mud and grass so i figured it got in the intake and clogged it up. When i got it home on the hose, i ran a wire up the pee hole, pulled the hoses off the thermostat housings and im not getting any water coming out anywhere. There is water coming out of the exhast hub though and the motor is running very cool to the touch. I guess my question is.. where do i start.. Im not really sure where i need to look for the clogging or if thats even the case..

Sorry for such a long post, just wanted to give as much info as i could. Any help at all is apreciated.

Re: 1989ish Not "peeing" but running cool...

The 'pee' from that engine will only be a trickle at idle due to the 'ejector pump' system to drain water out of the lower cover.
When testing cooling function on land, run in a barrel and NEVER on muffs!!

Re: 1989ish Not "peeing" but running cool...

Continuously fill the barrel with a hose, as the tell-tale empties it so that the water level doesn't get too low, and stays cool.

Also take off your water intake screen (the area of your lower unit with the screen mesh) and look up inside the water jacket with a flashlight.

If you see nothing, then blow some compressed air with a basketball needle attachment up the telltale hole and see if anything comes out the bottom (check the telltale hole first for blockage).

Re: 1989ish Not "peeing" but running cool...

I have similar problems and have changed thermostats and water pump. My engine runs at the proper temperature when run in a barrel but hot on a hose. This does not seem right to me so I called Evinrude and they agreed. I am going to do this this weekend. The tech told me to check the condition of the water tube (part no. 27) and the grommet (part no. 28 - cheap might as well change). Also make sure water tube is ALIGNED properly.

Oh! iboats won't let me link to WWW-boats-NET (truly sux!!!). You can do it. I went to my Evinrude 1987 90HP E90TLCUR and to MIDSECTION.

Re: 1989ish Not "peeing" but running cool...

the hose is meant to keep from damageing water pump,you can't let it run dry. you can only really test in a barrel or in the water. also on evirude/johnsons if the grommet for water pump tube is upside down it will cause all kinds of problems. I got a used lower unit that ran hot, triggered alarm any thing over 1800 rpm for 2 min. had a decent pee stream. when i checked water pump grommet/ seal was folded over, previous owner must have overheated his powerhead. dont trust how motor runs on muffs, get it into a tub or the water

Re: 1989ish Not "peeing" but running cool...

Not sure where you live but down here in NC we have "Dirt Dobbers" Wasps that like to plug holes with clay and mud and put their eggs in there. Just had a 15ft Henry O with a 70 hp Johnson come through that "wouldn't pee". Customer had a "mobile mechanic" diagnose it as a bad impeller. Ripped the lower unit off and made a mess (broke a water pump housing bolt.) Charged him $140 and left with the motor in pieces (nice huh?)

I fixed it all, put it back together, put it in a bucket and fired her up. Still no pee. So I pulled the tube from the water jacket and checked. Plugged solid. Hit it with the blow gun and out shot a chunk of mud and whatnot that hit the shop wall like a bullet.

Pees fine now. There was never anything wrong with the water pump in this case....

So check the line from the water jacket to the pee tube connection and blow clean.

They will let you link to marineengine.com
They have the same parts diagrams.

I also had a mud wasps nest... in my fuel connection.
It was right where the prongs are connected to the fuel line at the cowl.
They like the smell of the motor or something.

10 4 guys. I apreciate the help and input. Like i said, it was doing great out on the water all day just until i was coming back in. And it all of a sudden just quit peeing. Im gonna check all the hoses and everything one more time before take the lower unit off. I have to drop the lower unit to check that screen and all right? Its just really wierd how the motor is running cooler that ever and not peeing...

The screens I'm referring to are the mesh between the outside of the lower unit and inside which is the beginning of the water jacket.
But once you have the lower unit off look inside the water intake area of the lower unit and also up the water jacket tubes on the exhaust housing.

Don't be discouraged if you don't find anything...keep looking for the problem.

Re: 1989ish Not "peeing" but running cool...

So I got home today and checked all the hoses coming off the t-stat housings and off the little valve hooked to the throttle linkage. Blew them all out.. they were not clogged..

Checked the pick-up screen.. which theres hardly anything left of it, the mesh is all busted out. But there was nothing there blocking it..

So i dropped the foot.. checked the water pump key way.. it was good.. no clogging in there.. checked the water tube going up the mid section and as far as i could see there was no blockage, ran some wire up it just incase and found nothing..

Needless to say i didnt find anything... so i put it back together..

put it back on the muffs (only because i dont have big enough barrel to fill with water) and NO PEE stream..

I pulled the hoses off the t-stats while it was running and and theres just barley a trickle of water coming out.. i wouldnt even call it a trickle, more like a drip. But its still mind boggling how the motor is not getting hot..

So i dont know what to do now.. BTW whats the big deal about putting it on muffs or in a barrel.. I havent had any problems in the past with the muffs..?

But any ideas to where to go from here...? Thanks in advance

Re: 1989ish Not "peeing" but running cool...

If your saying that you have run the engine on the muffs for a significant amount of time...enough to heat it up for sure, and it is not getting hot...at all...then the water is circulating elsewhere.

Those things are not air-cooled LOL.

Did you blow compressed air into your tell-tale?

I blew through the tell tale with my mouth, i dont have a compressor at the house. But it was clear when i was blowing through it.

Re: 1989ish Not "peeing" but running cool...

Pull down the gearcase and hook the water hose directly onto the water tube. That will in most cases tell where it is blocked, if blocked at all!!
