Author Topic:   Lack of Snorkle Water When Outboard Run on Hose?

I ran my 1975 85 h.p. Johnson on the Hose this weekend and very little water ran out of the snorkle tube in the upper unit? I ran it for about 10 minutes and it still didn`t do it very much just a mist. I put my hand in the motor everywhere and even on the block, etc. and it was just warm and I could keep my hand there for a long time, what gives, it seams warm, but not very hot? Is this o.k.? Also, watewr was runnong out from betwee the connection of the lower unit to upper unit at the seam, is this normal or do I have a cracked cooling jacket? Any help would be very appreciated! Regards-Jack Graner.

Jack, I experienced the same problem on the 13 SS that i have at auction, except this 40 hp evinrude was getting too warm for my taste. What I found was a bad [thermo]stat. It has now been replaced and I now have water out of the upper vents, telltale and prop when running on muffs. Maybe on your engine you have a large amount of debris in the passageways. Are you getting water out of the prop once the engine has run for fifteen minutes? By that time the [thermo]stat should be open and allow flow through the block. Anyway just my 2 cents of input.

Thanks for the info, I'll check for debris and hopefully change the thermostat! I never thought of that, how about a bad impeller? Regards-Jack Graner.

I had a little bee nest (Mud wasp?) in mine last year. It really slowed down the stream, obviously, and was getting ready to change the impeller and somehow I noticed the clog.

If you are running on the muffs, you may not get much water out of the upper exhaust ports. On the muffs you have no back pressure on the lower unit water cavities and gravity takes over.

But with the stat opening properly you will definitely get output through the prop. With a bad pump you will not get even a tell tale stream. Jack, are you getting a telltale stream?

Thanks for all of the info guys! What is a Telltale Stream, is it that peee hole in the upper section of the motor, if it is no I don`t have one of those on a 1975 85h.p. Johnson or it is clogged? I will let it run for 15-20 minutes this weekend and observe everything and report back. I still can`t understand the water coming out of the case at the seams of the lower and upper case? Regards-Jack Graner.

Water coming out of the seam between the sections is not abnormal and is not indicative of anything being wrong.

I would check the thermostat first. The parts are so cheap you may as well go ahead and have them on hand. You will need the thermostat itself, the o-ring that goes around it and the gasket that goes between the two halves of the thermost housing. You should aso buy some gasket sealing compound to use on the gasket. All these parts should cost about $25.

You should also have on hand some sand paper or emerycloth for cleaning up the mating surfaces of the housing and some small wire brushes for cleaning up the threads of the screws that hold it together. Be sure to use some gasket sealing compound on these screw threads as well, it will help keep water out and prevent rust.

And no, you're '75 does not have a tell tale (pisser).

Yes, telltale stream is G-rated (and correct)
term for the pee stream.

Thank you all so very much for you`re help and I really appreciate it! This may be a dumb question, but where is a thermostat located on a 1975 85 h.p. Johnson, and is it a hard job to do? Anything on this would be very appreciated! Regards-Jack Graner.

If it is like the V6, there are two, one is located above the left a bank of cylinders and the other over the right bank. They are covered by a housing secured by several bolts.

I just called an OMC dealer for the thermostat and he said I don`t have the conventional kind in my motor, I have 2 sets of Vanstats which are tubes, check valves, and misc. parts. He said I would have to buy alot of different parts and he doesn`t have the gaskets in right now. It seams I don't have the conventional thermostats like the car ones like the newer outboards have! Does anyone have a clue to as what thes Vanstats with all of these misc. parts are and how to deal with them? Also he said he has been getting new parts for OMC motors for about a month now, and they are making them again slowly, but Bombardier won`t say where! He said he can now order parts for OMC outboards! Yeeha! Regards-Jack Graner.

There aftermarket parts available for that system from both Aqua Power and Sierra. Aqua Power has a rebuild kit #2658 that runs about $25.00.

I will e-mail you and attach a copy of that parts page.

What is a "snorkle" tube? Is Jack talking about the telltale/confidence stream?

Thanks guys! I will buy the rebuild kit, it seams it would be easier that way. JimH, I was refering to those 2 holes at the top back of the engine that throw a spray of water when hot, they look like nostrols acctually? I still don`t understand those Vanstats, seams like alot of intricate parts? Regards-Jack Graner.

I believe that the "snorkle tubes" are technically called back pressure relief openings.
