cooling on Honda 40

I went for a little cruise yesterday. After starting noticed port engine 'dribbling' water from cooling vent. I fast idled. Flow of water stopped!

I lifted motor...inspected intake...dropped...started...now water...stopped...removed hood...blew through hose...droppped motor...started...no discharge...lifted motor...removed hose from the discharge 'nipple'...dont know if this is right term...dropped motor...started...water galore. I ran a little wire up the nipple from outside...and discharged a slug of 'goo' about half the size of a grain of rice. Hard to believe that was the problem, but it certainly was. Anyone else with this sort of problem?
 
All the time on my Hondas on the 22and the 16. That tube is a favorite spot for bugs of all kinds. Kept a pc of wire in the well for just that purpose. If they really overheat, the warning light/buzzer should come on! You did just the right thing!

Yes, I have had the same situation on my honda 40's. I have had minimal discharge even with a new impeller and tried running a wire up the "pee hole" with no improvement. But I found the clog to be on the other end of the little hose at the fitting on the motor housing. It seems that the passage is more likely to be obstructed at this end of the discharge tube.
I have run the motors in a tub of vinegar and lime-away and it seemed to help.

Weed wacker line works real good up the pee hole.
:shock: :cry

Ouch...oh you meant.... :oops:

Charlie- I thought of that too!

Fortunately, when Captain Catheter comes calling, usually Captain Morphine is still around, or some other anesthetic just used in surgery.

Then there's the Urologist with the request for a quick "look-see' with the Medical Bore-O-Scope! All sing: :note "You Light Up My Life,……." :note

Better get back to the original thread, before anyone gets bored, so to speak…

We now use a piece of duct tape over the pee tube's exit on the motor to prevent mud bugs or whatever they are from crawling up in that tube and clogging it up with there exhaust mud or what ever they leave behind. I just put a note with a piece of tape on the steering wheel to remind me to remove the tape from the pee holes exit. Seems to happen more in the early spring in our area.
D.D.
 
I too use weedwhacker line. I keep a piece handy and when the flow starts slowing down I lay over the motor with a small mirror and guide the line up the opening. I too find that it is usually at the engine end where the flow is obstructed. My 35's were used a lot in salt water before I purchased them and I doubt they were very often flushed with fresh. I am guessing there is a lot of salt built up in the cooling channels. Sometime I am going to find a way to rig up a reservoir full of vinegar and go at them.
 
The mirror is a great idea. That is most challenging bit when you can't see and are hanging over transom. It is always the outlet fitting where reduction in diameter seems to facilitate clogging. You would think Venturi effect would help to eliminate plug but nooo...
 
DD - good idea with the duct tape. We have a lot of mud daubers around here as well.

As I understand it - IF it is just a plugged tell tale, the engine MAY still be getting cooled. Like Charlie said if it is actually overheating the warning buzzer/light should activate.

Funny story --- years ago we were at a marina on Big Creek(Long Point inner bay, Lake Erie). From the mouth of the creek it was over a mile run along a marked channel to get out into the bay. It had to be done on plane as it was shallow, narrow and heavy weeds on both sides. One time my water intake must have got clogged with weeds. My water pump was fried but we made it back in on the kicker. The next time we went out my grand daughter was with us. I gave her the job of keeping an eye on the tell tale - which she did religously. When we got the Stingray(stern drive) we took her out again. Shortly after leaving port she came and said to me "Grampa, I can't see the water". At first I thought the seats were too low or something -- then I realized she was looking for the tell tale!! :lol:

When I first got my hondas I worried when nothing came out the so called pee hole. I have found they get easily clogged with salt and other contaminants. I don't really worry about it anymore until an alarm goes off. Then, it is time to stop and put a new impeller in it. I guy should probably do them periodically anyway just to make sure the bottom end comes apart.
 
Over 900 hours on my twin 40's and they have never peed strongly or consistently. 3 new impellers during that time and even then they would be weak or nothing. I quit worrying 6 years ago.
