No water peeing on Johnson 225

[mstead]

Hi all. I will make a long story short. 1996 Johnson 225 has been sitting up for 2 years. Rebuilt starter, W and the motor starts immediately, however does not send the water out of the "pee tube". Where the elbow at bottom of engine casing is, plenty of water pressure with hose removed and increasing as throttled up. Assume the impeller is working because with engine cranked, there is no spillout at the ears, and I have water at the first elbow as stated. Seems to have some sort of junction valve that moves with throttle. Just need to know where to start to diagnose. Water pumps? (seems to have 2). Have not run it for more than a minute because I didn't see it peeing. Is there a thermostat that has to heat up to get it to pee? This motor was new to me 2 years ago when purchased and circumstances had it sit for 2 years since purchase. Any advice appreciated as this full on boating season is here and I am shut down. Thanks!

Re: No water peeing on Johnson 225

Couple of issues to correct you on....
1. The engine has one water pump located in the lower unit.
2. A 1996 225 does not have any kind of water valving system on the throttle. That was earlier, around 1991. If you have the water valving system, you also have a problem with the actual year of the engine.
3. The thermos do not have to open before you see a pee stream.

Look at the center of the rear of the engine, just below the cowling joint, and you will see a plastic fitting for flushing with a hose. That is the pee-er. Remove the 13/16 plastic nut and clean out the pee-er fitting, re-assemble. Test.

Re: No water peeing on Johnson 225

I do not have the model number in front of me as I am at the office, however, I cross referenced it before and it said it was a 96, however, you sound like you know what you are talking about, so lets assume it is a earlier model. The valve that is moved by the throttle has 3 hoses going into it, then one hose goes to the top back of the motor into a box (that I was assuming was some kind of pump), a hose takes it to the other side of the engine into another identical box, then I assume goes through and cools that side, then comes back out into the pee tube which is located on the bottom right (if looking from the back of the motor). I will try to flush it. Where is the thermostat???? Should it begin to pee immedaiately or does it take a minute or so for the water to make its way through? Thanks for your help!

Re: No water peeing on Johnson 225

As I said, a 1996 model does not have the water valve control on the throttle linkage.

The "boxes" you are referencing...I am trying to picture what you are talking about, and the closest I can come is the thermostat housings. They are at the top of each head, have hoses running to them. Four bolts attaching. There are two thermos, one under each housing cover.

Should take just a second to start peeing, and the factory pee-er is where I told you it is, on a 1996 it is dead center of the lower cowl in the back. There is a fitting there for hose attachment for back flushing. When engine is in operation, the pee-er is there. Any other pee-er you are seeing is not factory on a 1996 225.

I don't think yours is a 1996. The engine year code is EI for 91, EN for 92, ET for 93, ER for 94, EO for 95, ED for 96.

You should have an engine code like this: E225TLED, where ED is the year code for 1996. Find out the year, and look at parts drawings on shop.evinrude.com.

Re: No water peeing on Johnson 225

As daselbee explained,your engine is pre 92.It has an aspirator system that is designed to suck any water that may fill your cowling ,it operates off the pee stream.You can take all the system apart,remove all the hoses and clean of any debris,the part you believe is a pump is a valve,by cleaning all the passages you may get it working again.I would disable the system,the newer engines were deleted of the aspiration system,could be that they came up with a better sealing system.Or,found as most customers,the system failed.You might find more info on the BRP (bombardier,new OMC owners)website.They have a great system for parts diagrams.If you cant get the system working,,you can figure out the hosing of 1993 and newer engines systems.As for the peeing.Your eng is likely pumping if its not getting hot.You should insure your overheat system is working.You can leave your key in on position,while not running ,find the 2 heat sensors on top rear of eng on top of the heads.they are tan or lite brown,disconnect the pull apart connector,then ground the wire that comes from your harness ,you should then hear the heat signal.If your lucky enough to have a temp guage too,you can use the overheat and temp guage to insue your not overheating.I see no reason to keep the aspiration system,it does malfunction and actually can fill your cowling with water when it does

Re: No water peeing on Johnson 225

Thank you both for the excellent information. It sounds like my engine is definately not the 1996 I thought it was. I will recheck the # when I get home. It definately has this aspiration system and I will see about disabling it. That said, since it goes through that fitting on the throttle, do I just pull that hose and plug it? Like I said, the impellor seems fine, as it sucks water up and doesn't spill out of the ears with the engine running. That leads me to think there is a clog somewhere so I guess its just a matter of going hose by hose and checking for clogs. The boxes I was referring to are at the top of each head, so I assume as you stated that they are either thermostat housings or temp sensors. Will try your advice and post results. Thanks again!!

Re: No water peeing on Johnson 225

Update- Got it to pee. The hose from the aspirator valve was clogged and I was able to blow it out and presto- pee. Now fuel pours intermittenly from several of the carbs so I think I need to pull them all and clean them up well. Seems like a float is sticking or something, which is to be expected after sitting up. The number I can see on the motor looks like J225txeda or
J225txcda. The cowl says Johnson 225 VRO. What does this mean? sticker is a little banged up but the only letter in question is whether its an "e" or "c". Thanks again!

1986 I N T R O D U C E S
1 2 3 4 5 6 7 8 9 0

Thats the code ,your CD =86.That is proved by fact of the aspirator which ended 91-92.
Glad you got it solved.As for the impeller.It should be changed long before it gives trouble.Here in Fl.yearly,but you can go longer ,dont recall the manufactures suggestion.BUT,its always better to be safe.I wouldnt go longer than 2 yrs.Its just as bad to not use than use.the vanes in the impeller will take a "shape"like an octopus after a while and become brittle ,less effective.Gear oil tooo at impeller change ,or at least 1 time yearly,you want to find any water before its too late.If you suspect carb trouble.Do them,you dont want that eng not getting fuel to a cyl.no fuel+no oil.No oil ,your in trouble.

Re: No water peeing on Johnson 225

I feel like an idiot. Doing a bit more research, I found that on Johnson for that time frame, the year is the second and third to last numbers, so I have a 1986, not 1996. Guess I should have done homework before I paid the seller the asking price and replaced stator. Oh well... Didn't think of the no oil situation- Thanks big time for that. Will not run it again until I do the carbs. I changed an impellor on a 25 about 6 months ago so at least I have an idea of what to do. Thanks again!

Re: No water peeing on Johnson 225

I know this is a bit old, but how would I go about bypassing these valves? Also, mstead did you have to remove your valve to blow it out?
