pee hole clogged

jennykatz · Posted: Thu Sep 09, 2010 8:04 am Post subject: cal. build up

We just did maintenance on our F115 Yamaha we took out the zinc's that are built into the engine there are 3 of them in the 115 yami then we put a hose into the hole you cannot believe the crap that came out of there .I also do the impeller every 200 hours or so .I run fresh water after every saltwater trip and do salt -away twice a yr.The pee hole runs very strong once in a while I need to clean out

Look at the zincs and clean out as needed and use salt-away or C L R this should do the trick

I picked up some CLR should I use it undiluted or cut it with water.

Tom i would cut it with water, l'm reading from the CLR instructions and it says for cleaning a coffee maker its ...1 part CLR to 8 parts water. I would try that and if that fails to do the job you can always try a more concentrated solution. Let you know how it works..i bought some but never tried it yet. Tug

I took off the brass nipple again, this time I found some sort of black rubber bits clogging the hole. I was very soft (not like the impeller)??? I let it run with the nipple off I cleared the blockage again.

I used the clr its soaking now. Im giong to run again this evening with thr nipple off after a good soak.

Tom ..i wouldn't let it soak too long at first go anyway! The instructions say just a few minutes but good luck and hope it clears all the gunk out. Tug

the black gunk (rubbery) could be the rubber seals for the zinc's Find the zincs in your engine then take them out and you will find rubbergaskets take those out put new gaskets and zincs in after you clean out first what kind of engine do you have yr and make call your dealer and find out where the zincs are on your motor very important to do

Like I said before doing normal maintenance we took out the zincs and put a hose into the port where the zinc goes and all soughts of crap came out of there and the rubbery black gaskets were ready to fall apart and we changed them last year 150-200 hrs ago

its been about two weeks since i treated the engine with CLR. I think pulling the nipple off and letting the engine run was key to clearing the clog.

so far the pee hole is pushing water out very well.----thanks for the recommendations and support.

I had the same problem with my twin honda 35's. Previous owner only used the boat a couple times a year, always in salt water. It plugged, on both motors, every hour or so. I would push the wire up the hole to get flow going again. Then I graduated to pulling the cowl and pulling the hose out of its' seat on the outflow end and it would take off. Then the weed wacker line up to the block. One time I actually found a chunk, which I pushed out through the cowl with the weed wacker line. It was salt. I haven't tried salt away yet but will soon. I have it down to where it only occurs maybe every 5 to 10 hours.
