The old "enough water in barrel" question

[WimJall]

So conflicting for me.. My 1967 evinrude runs great, but I don't get a stream of water out the exhaust when running it in a barrel of water. I have the water line half way up past the 'shifter rod connection plate'. I fill the barrel and let it sit for a bit so I think its priming.
Last year I had it in the water once until it broke the shear pin and never had time to get back out.
Now I'm looking to get out and I ran it in the barrel and didn't get a "stream" of water out the exhaust. If I hold my hand in front of the exhaust my hand would get wet but never any sort of splash or run of water.
Has new impeller and seals. The faces are not scored. New thermostat. The little plastic ball under t-stat is there. And I can hold my hand on the head without burning.
I made sure to turn the shaft clockwise "while looking down on housing" when installing and everything seems to be right.
After running I pulled t-stat housing off and there is signs of water on top of t-stat but may be condensation.
Any thoughts?

Everything you've written is confusing.

Of course your hand got wet - You stuck it in a barrel full of water or should have to feel the exhaust, which isn't a good idea. Water doesn't stream out of the exhaust like a hose, it kind of spits.

I think you're talking about the idle relief port, which also spits.

You might want to ID the motor for us - 1967 Evinude just ain't enough.

Ha sorry, its a 1967 Evinrude bigtwin 40 HP. 40752E.
No I'm not sticking my hand in the water lol. I'm talking about the 3/4" hole that is just below the cowl, that should have water coming out of it. I realize that water will not run out like a hose, but I have more condensation coming out then any sort of water.

There will only be a bit of water blowing out there till the thermostat opens. More blowing out when open, but never a stream. The 'stat constantly samples the temp and opens and closes as required to maintain proper temp.

Having said all that, "condensation" is not enough.

Any suggestions? Pulled lower unit off tonight, and checked impeller. Keyway is there, and impeller was facing in correct direction.

Like I said - The idle relief spits. If you hold your hand there long enough, it will get very wet.

Most of the cooling water exits through the exhaust, not the idle relief.

You said the motor isn't hot, go boating.

 

[kbait]

I had the same motor. No/little water until thermostat opens. Then some would spit out..more at higher rpms. Just check head temp and go boating.

 

[WimJall]

Alright! You can call me Larry, because I'm just gonna send it!

When that motor was new it would.------Spit a little water out of that exhaust relief hole on warm up and idle.-----If you were water skiing behind it water would POUR out of that hole.-----Then on slow down and idle it would diminish to spitting out a little water again.

Our 1963 40hp would send various amounts of water out of the relief, the amount varied as to engine temp, engine load, temperature of the water in the lake. Engine had an Idiot Light for overheats, and it lit up on regular basis. Pump was good, new stat, pressure valve all ok. It was always pumping lots of water out the relief when the light was on. In hindsight, I think the problem was from the old man putting a large quantity of sealer on a Head Gasket, and some of the goo blocked some of the transfer holes. Sold the motor before next summer.

 

[WimJall]

Well she ran great as expected. Took it to the lake for a few hours. Now just need to figure out how to raise the idle so it doesn't stall when shifting F to R.

#37 is idle speed control

 

[WimJall]

Is the small screw and collar the idle adjustment?

Or does it have something to do with the two screws on the end of the throttle cable?

 

[jimmbo]

The small screw and collar are part of the Fuel Saver Linkage for that motor. Don't mess with it. If you messed with it, you will have to reset it properly.
The two screws on the Throttle connector, are there to kink, and then to anchour the cable to the Throttle Connector

There is an idle speed adjustment screw on your engine, it should be located on part #41 on the drawing supplied by F_R, right behind the emergency throttle lever. There might also be a screw limiting the throttle lever on the remote to set the idle speed

I can't make out the image F_R posted to compare it to my engine and find said screw. Currently trying to upload image of my carb so maybe y'all can help point it out. Just need to resize photos.

The screw and collar in picture #13 are often adjusted by a novice.-----When it is " right " it looks wrong.----Do not touch that.

Yeah that's what I gather. I'm just trying to decode the image F_R posted. I don't see anything in that general area with a knurled screw that is adjustable..
On one of the images I posted you can see a larger "screw" just above and to the starboard side of the carb that is knurled but I don't think that's the screw being spoken about.

 

[WimJall]

You can see the only knurled screw I found here.. Its just about the choke lever seen in this photo.

 

[F_R]

Ooop, I think you got us on that one. That is different than the bazillion models we've worked on. In fact, I had to look it up in the book. Yep, that's the idle speed adjust screw.

 

[WimJall]

No worries F_R ! Sometimes it takes a young chap to refresh y'all memory. Glad we got this hashed out. Can't wait to get home and tune her in. Thank you very much for your patience with me!
