not getting any water discharge from my honda 9.9 outboard . I replaced my thermostat . replaced my water pump . still no discharge . any ideas what else to check ?
 
Hi,
Do you mean there's no water coming from the tell-tale?

If so, that usually means something is stuck inside the tell-tale bypass or in the tube that sends the water to the fitting on the starboard side. Sometimes it's actually something tiny stuck in the fitting itself. But most of the time it's debris (grass, twigs, pebbles) inside the engine block.

It's usually necessary to remove the hood and right side under cover and disconnect the rubber tube at the fitting in the engine.

Sometimes you can knock whatever is in there loose by feeding wire or grass trimmer string into the passage and pushing it down as far as it will go.

But I have found that only works once in a while.

I find it more effective to remove the fitting from the block and then start the engine. That almost always works but water will shoot out with quite a bit of force and make a mess. It comes out so strong it could hurt you, especially your eyes.
So, if you try that, protect yourself and be ready to shut the engine off immediately.

Good luck.
 
It's a TRUE PAIN the first time.

Pay particular attention to how the little rubber tube is routed because it's VERY important that it goes back on correctly. If not, pinching the tube closed when you put the lower side cover back on is pretty much guaranteed.

The tube has to go through a hole in the splash plate so that the side cover doesn't pinch it. Take the cover off slowly and carefully to get a good look at how it's routed so that you know.

When going back on with the cover, it should feel like playing "twister yoga" if you're doing it alone. Because, the tube MUST be attached with one hand while holding the unattached cover with the other.....Sheesh!

A good trick is to use a small drill bit to slightly oversize the plastic fitting hole. Don't use a drill though! Turn the bit by hand!

There are two fittings in the side cover. One is for the tell-tale and the other is the carburetor drain. You do not need to oversize the carb drain fitting.

OH!....
...and....
That little tube MUST be soft and pliable. If it isn't, it will tend to catch tiny little things like pebbles, grit and twigs where it is bent.

i replace the tube on mine every three years or so because of that.

BOATING CAN BE FUN!!

("when the maintenance is done" :)

Good luck.
 
I’ve had the same issue on mine. I’ve been able to clear it by removing he tell tale hose from where it exits the engine under cover, straighten it out and clear with grass trimmer string while running the motor. Last time I noticed that water was also slowly dripping out the relief valve on the water jacket. To fix that, I had to remove the thermostat and water jacket, and was glad I did because it was a salty mess in there. Much cleaning and o ring and internal anode replacement later, she is running like a top! Good luck.
 
Great tip about cleaning under the water jacket Deuxgrenouilles!

Especially if it's used in salt water.

That's the place to access and replace the sacrificial anode and those often don't ever get serviced.

Too bad too because they help extend the outboards life by years.

Always replace the screw that holds the anode as well because, if left in place too long, it will sieze and break off. Then, you have to drill it out and that is tough because it's so small. Usually leads to redrilling the hole and tapping in new threads.
ANOTHER PAIN on these!
BUT.....
...necessary if you don't want MORE problems :>/

Worlds FINEST twin cylinder outboards with just a FEW maintenance headaches that can aggravate.
 
back at it today. thank you for the helpful suggestions ,
following the tell-tall hose back . only to find it unattached.
I looked every were for that hose connection to the motor . I even removed the carburetor .
after reading the suggestion and comments I see why that hose was unattached.
I do have a honda shop manual for my engine ., no information on tell-tale.
I did order a new hose ,and a internal anode and screw,
like many , that learning curve is challenging
will try again tomorrow
 
If you are going after the internal anode, you also need to replace the complicated o-ring that seals the water jacket cover. Best to read that section of the shop manual carefully as it mentions a few different seals that should not be reused if the motor has seen salt, you will also have a cleaning task when you get that water jacket cover off as it gets pretty gummed up with salt in there. Because to put anti/seize, or grease or Vaseline on bolt threads before you reassemble. Those bolts will come out way easier next time.
 
Again, great info ffom two frogs.

I will try to find a depiction of the hose fitting for you.

The hose comes off because there's a plug up. That's why I suggested replacing it periodically and enlarging the fitting too. There's NO WAY that little hose can stay on the fitting when there's a plug due to what I can only describe as the incredible power of the water pump.

Also, there's a little spring clamp that's likely missing now (just like the ones on the fuel pump hoses) that, even if you replaced it with a better, stronger screw type clamp, wouldn't do any good because, more than likely, a future plug would just result in the hose bursting due to water pump pressure.

A small zip tie is all you need to secure the hose on the fitting.
 
Well, the only reference I could find that indicates the area where the tell-tale fitting is located is is in the very poor link below:


Item 41 is the tube and Item 36 is the tiny clamp I mentioned.
Following the black line from the clamp indicates the area where the fitting is screwed into the engine block.

The F8 reference at the top of that tube indicates the page for the engine cover and under covers.

That's where the tube would route to connect to the tell-tale fitting on the starboard under cover.

Sorry I couldn't find anything clearer for you.
 
update I installed a new anode and screw with new gasket
now on my yearly to do list.
after looking were the tale-tell connect to motor for 3 days , taking off stuff looking
. I was unsuccessful in finding anything . watched A ton of videos, really no help on a 9.9
what a great learning experience , most part I know my motor . thank you to JGMO, and DEUXGRENOUILLES
 
Wel, you shouldn't need to replace the anode every season. More like every 4 or 5 in my opinion.

To locate the fitting or where it's supposed to be, you may have to put the lower end into a trashcan of water and run the engine.
Unless that passage is completely blocked, at least a small leak should lead you to it.

Just be cautious because you WILL be injured if the full force of that stream were to suddenly hit you in the face.
 
thank you.
replace tale-tell hose rightside under cover .
used hose to guide to every location it could fit
ran motor in a 30 gallon drum , no leaks
next added food coloring to water to see if any leaks I could follow ,
hard to believe its that clogged ,or I cannot find that connection
 
Yeah, it's plugged up TIGHT!

You'll see what I mean once you do find where the fitting goes, clear the blockage and then run the engine in the trashcan.

You probably won't believe the force of the water coming out! I know I was shocked the first time I experienced that.

Just a guess but I suspect that the fitting may have been cracked by whatever is plugging the hole and then snapped off. You may even find it down lower if you look around. down there.

That would leave a situation where the blockage and what's left of the fitting is flush with the engine's surface and explain why you're having such difficulty seeing it.

If it's hardened mineral deposit it's likely that the color of that stuff might be matching the color of the aluminum engine or the paint.

The scary part is that, once you do find it, you'll have your work cut out for you clearing what's in there!

I can't wait to see what you report once you do find it so PLEASE, keep us updated. We're rooting fer ya!📣

Good luck
 
back at it again today . plugged water tube in lower unit , threw to thermostat hole , fill with water . with a oil extractor. pulled water out .
ran motor , got a trickle of water out of tale-tell on motor . cleaned fitting . I did find that the original hose from the tale-tell was smaller that the new one I replaced . but success thank you for all the helpful suggestions
 
Well, glad you had some progress. But if you didn't pull the fitting out of the engine and then run it, I think that you may have another no tell-tale stream issue soon.
Just my opinion. Hope I'm wrong.
Good luck.
 
yes pulled and cleaned that fitting , I have a good stream now , engine running well
strange that from the factory . they had the wrong hose on ., and inverted the carburetor hose and the tale- tell
thank you
 
Yes, it's a mystery what goes on in the factory sometimes. I have purchased brand new parts from Honda in the box, inside a heat sealed plastic bag, that had sand inside them.

I once found the crankshaft retainer nut under the flywheel "floating" free along with the big washer it held down on a brand new BF8D. The reason I took the flywheel off was because there was a distinct ringing noise when the engine was idling.

I guess they have parties on Friday night that the workers want to get to early in Japan too:)

Could have been a Saturday morning work assignment after a Friday night party?
