Johnson 6 Hp Seahorse Motor Manual
Hello, After putting my boat on the water two weeks ago, I discovered that when I fired up the motor, there was no water (cooling)stream being expelled from my Johnson 6hp, kicker motor. I stored the boat in an unheated garage during the winter. I conducted a visual inspection of the intake port at the bottom of the motor and found that it was clear and intact. If perhaps there was any frozen water in the lower part of the motor it would have melted of by days end, the temp was 60 degrees. I'd like to get into the motor to troubleshoot it myself, before deciding to take into the dealer. Can anyone offer any guidence or suggestions?
I haven't had the time, but I'd like to get into it this weekend to have a looksee. Thanks in advance for your help. Pete C, Colorado. If you are talking about the tatle tale where the small stream of water comes out these often get stoped up and all you need to do is clean it, also keep in mind these motors have a thermostat and it may not of opened yet.
You can take off your cowling (engine cover) start it and put your hand on the top of the egine to see if its getting hot, you should beable to keep your hand on it for a few minutes, it shouldnt be so hot you have to remove your hand quickly. Most of your water will go down the down housing and out by the prop, and about 15% will go out the hole in the rear of the down housing. Just a couple of things to check for.

#1 Pete is check to see how hot it's getting with your hand. Start it up and hold your hand on it when it gets to hot to hold there anymore shut it off (watch your fingers in the flywheel and other moving parts). #2 Pull the pee tube off and see if it is plugged.
#3 Pull the thermostat out using the same gasket put back together and restart. This is very simple there are 2 bolts holding it on the block just like a car has. #4 Pull the lower unit off and replace impeller.
This may not be true on a johnson but I'm speaking from experience with a 9.9 yammy. I checked the pee hole tube and it was clean. Then I replaced the pump impeller. Then I was trouble shooting and when I would pour water in the pee tube it would run out just below the motor so I figured I had a leak in the tube running to the motor. So I yanked the motor off and the oil sump plate and the oil sump and there was no leak. I could not for the life of me understand how an engineer could design a motor that would not pee until the thermostat opened. You would not know if you had cooling until the motor overheated with this design but that is the case and without a service manual ( been trying to get one for 4 weeks) it is very hard to trouble shoot.
The water I saw leaking under the motor was from the pee hole tube I was pouring water into, but thats on the discharge water coming from the motor and it discharges into the same area as the exhaust which is right below the motor and oil sump. After all this I decided to pull the thermostat 2 little 10 mm bolts and put it back together with out the thermostat in and lo and behold it pees. This is my trial and error theory and you get to know you engine well but it's a lot easier to have a manual and do it right the first time.

The hardest part to replace is the pump impeller so do the 1st 3 things to make sure you need to. The impeller is also not that hard just make sure you get the water tube back in the discharge of the pump when putting the lower unit back on and put grease on the impeller and the splines that go into the bottom of your motor. Also remember how many threads are visible on the shift linkage rod to get it back the same as before. This may not be the same as you johnson so get a good manual before you start.
I hope this helps Pitts.
