wont pee

stupid newbie question, i have 2005 115efi merc 4 stroke. ive prepped up the boat for this year. juiced up the batts changed the oil. i put the ear muffs on the garden hose fired it up and let it run awhile temp came up to about 120 or so. then i noticed that nothing was peeing out of the discharge. the temp alarm never came on the engine felt warm. so i guess the question is why isnt the discharge peeing ???? i thought maybe the thermostate was stuck so i removed it water spilled out the top of the block ” while running ” im wondering now if the water pump is shot??? oh yeah the thermo works i put it in some boiling water watched it open. any ideas?????

a couple things I would try first. With everything hooked up and running, try shifting it into gear, and let it run in gear for a while. see if it does than. If it doesnt start than try giving it some throttle. If neither of them work make sure that you are fully covering the water intake and it is getting water up to the motor to begin with. Try that and report back if that works

The pee hole is there to let you know that the water pump is working; it’s not the main exhaust for the cooling system. It’s not under great pressure so a small piece of junk can clog it up. Take a piece of that plastic string stuff used in a weed eater and fish it up the hole. That can clear out an obstruction and get it pissing again. I had to so that with my Merc after sucking up some weeds and sand near shore.

Thanks to Jon Jordan for the idea!

ok will do

A bottom bouncer works great for cleaning the junk out of the pee hole too. Nice flexible wire and easy to hold on to when you are reaching around the motor (if you are out on the water).

I had similar issues with a Mercury last year. I’d suggest checking for obstruction in the line, but perhaps taking it to an access (if one’s close by) or a bulk tank, and running the motor while the boat is on the trailer. If the muffs aren’t on just right, there may not be enough water going in to the motor. Just something to consider before replacing things that may not be broken.

Something to remember is your waterpump on ly pumps 17 or so psi your average gardenhose has anywhere between 30 to 50 psi. The pressure from your hose will cool the motor to fast and sometimes not open the thermostat and you truthfully cannot tell if your waterpump is working or not. I would try opening up the pisser tube and if that dont work i would bet money on a waterpump. Just went thru the same thing with my suzuki. Everything went fine on the garden hose but on the lake the over heat alarm was constant. They also recommend a new impeller every two years as routine maintenance if you have never changed it since new you are about 2 years overdue. After my expierience i will change mine religously.

If you had your boat outside those mud daubber wasps always find the pee hole to plug up happens on my small motor avery year.

Some engines also have more than the two intakes. Some have yet another under the bottom cavitation plate. You need to use duct tape to seal them, and then try the ears.

If that does not work, leave it run until the alarm goes off. You may not be letting it warm enough for the thermostat to open.

One other thing to check that I just thought of. To see if it is clogged somewhere in the line, follow the rubber hose from the pee hole back to the motor. Pull off the clamp where the hose is connected to the motor and pull the hose off. Run the motor again and see if water comes out right from the motor. If it does you have a clog somewhere in the line.
Just another idea to try

I have virtually the same engine (2004) and had similar issues last year. Got the same advice here to try the weedeater line to see if that was plugged. I could not get that stuff far enough into the line to really make any difference. I did pull off the clamps and really went after it.

If you are a good DIY, try some things, otherwise, on a motor of this size and being relatively new, I’d get it in to a shop. Mine was a water pump. Nothing I could do for it.

THAT”S A AWSOME IDEA. ive got a spool of the ready handy. i”ll let you know

Did you try blowing in the pee hole? Just don’t let anyone see you do this….they might think your nuts!!

Won’t Pee??? You may want to back off of the Viagra a little bit.

CLEANED OUT A BUNCH OF MUD!!! out of the tubes with a piece of wire. still plugged some where inbetween the water pump and engine. seems to have a tee fitting under the chaps perhapps a reducer the wire i had wouldnt go thru it. i disconected the speedometer blew air threw pegged the speedo. pushed the wire tru that way didnt get to far any way barking up the right trail thanks again guys

NAW I USE THE STUFF THAT GIVES YOU THAT SILLY GRIN AND WAVE !!!!!

WELL I TRIED ALL THAT STUFF still no go. i ran wire tru all the hose”s compressed air too. pushed a bunch of crap out. pulled off the chaps cleared all the hoses there. put the muffs” just cracked the spiggot” water was pissing around the muffs on fired it up. nada zip nothing. ran the temp up to 185 or so. pulled a 5/8 hose coming from the tstate housing to block. just steam. one real odd thing though. the hose going to the speedo is connected on the motor to what looks like a hydrralic cylinder, i suspect it is the gear shift rod fairly stout 5/8 3/4 dia shaft. air and muddy water blew out off the area where the steel rod enters the gear case. i suspect i have another problem now if i am correct this would let gear lube out and water in the gear case. any way im going to take it in. throw in the towel bite the big one. bend over and take it like a man. ” i hate it when that happens” any way thanks for the tips and tricks guys. any thing i missed

Im not sure on the mercs but some motors have a hose hook-up to flush the motor itself out. May want to look into that and see if it is possible.

Did you runn your boat in real shallow water or has the motor drug through muck or sand at all lately?

last fall on the last outing i ran into slit/sand river fishing the water was low i went out just before things iced up. the dam had released water for the draw down. i got stuck in the muck while drifting with the currant. ive never had this happen before. COLOSSAL DUMBASS POINTS FOR ME !!!!

Sounds like one or two things or maybe both. One being the motor is badly clogged including all hoses and such of muck and sand, and or you spun your impeller due to all the muck and sand. I would look into seeing if that motor has a way to flush it out. If not I would say bring it in if it was me.

Found a shop near me who canlook it over. dropping it off sunday. i”ll let you know what they find out. on the plus side. took the little boat out. on wonder lake il. 2 small northern by the dam. on white willow leaf spinners. cruised in by where the creek feeds the lake. other boats said it was slow.
