New to me.....What do you see?

[FirstRealBoat]

This is a 1967 Evinrude 18 HP. My comment will be with the pictures.

Thanks for looking and your replies.

Data Plate. Looked up number 1967 it is.


Dirty it is!



This is on the side to the LU, what does it go to? I can't seem to understand the service manual I downloaded for this model.


This was nasty! Looks like the stop screw is broken, actually it fell off while I was cleaning it. Now what?
I don't under stand this throttle at all. It has a flat spot and only turns 180 degrees if that?



Missing the adjustment, have to take the cover off to adjust the mixture. Where can I find this part? I would like to get this working right.



Nice cable tie....bwhahahah, I will be changing this. Do I need to rebuild the fuel pump? or just clean it so and put back together?



Hole with missing adjustment screw. I whipped this off several times to get it this clean. This thing had so much grease on it! Nasty over greased everywhere!



Linkage was covered in grease..... But new wires for shutoff button! That's one thing that clean...haha



What does this lever go to? It is spring loaded but not attached to anything?



Nice weld job, it is solid, but not clean. Hope it holds!

Thanks for looking. I will take more pictures as I start to clean carbs and pull LU for water pump replacement.

This motor runs as is, but doesn't pump water. So I shut it off after 3-5 seconds. The service manual I have isn't very informative. What is the best way to take the LU off and replace the water pump? What do I need to watch for? Is it as simple as drop it, slide off shaft and replace with new gaskets and impeller and put back on?

I can't seem to find any video's of these engines being worked on like I have for the JetSki and Mercury motor.

Thanks for looking.

The oval plate with the two flat head screws is the cover for the shift linkage. When dropping the lower unit you must completely remove one of the two bolts in the brass connector.

Original owners manual and service manual are available from Ken Cook at www.outboardbooks.com

What about the manuals that are on iBoats? Not the Selco but the one advertised as original?

It's only $2 more than the link you provided, but is it the same.

Thanks

Brass connector? Where would that be at?

Thanks

Yes they look like they are the same. I had not realised that iboats sold them.

I dont know how the prices compare . I get the prices from iBoats shown in GB pounds

Behind the little plate in your picture. It joins the two parts of the shift rod.

Looks like parts are missing on the carburetor.-------------The " lever " on the side does nothing other than mount a wee bracket to attach remote controls.

I think the parts are the mixture knob. Where can I find this? I can run the motor without it, just have to take cover off at start up to adjust the screw then put cover on again. Annoying!

 

[hardwater fisherman]

If it is the mixture knob. Once set there is no need to adjust unless carb has been taken apart for service or cleaning. There are used manuals for your motor on EBAY.

OK-----Is there a roller that contacts that brass cam?-That would open the throttle as ignition advances.-----Words of advise for you.-------Look this motor over very carefully BEFORE you spend any hard earned money.-----Be a shame to install new parts on a motor that is in very poor condition !!

There is a roller that contacts the brass cam that is under the flywheel.

From what I can tell, it looks to be just a bit dirty and missing the mixture attachment. Did a compression check and both cylinders were at 95 PSI. I don't have much into it thus far. If I can get away with less than $200 in stuff, parts and crap.......I would be happy. My 16' alumacraft would be about to hit the lake finally with more than just the trolling motor.

One question for all, how long does the motor run till the thermastat opens and water starts to pump? I started it last night, after cleaning it. It ran for about 15 seconds, I noticed only smoke coming from the LU where water and smoke should be coming from. How much run time do I have till it starts to overheat? I want to test the thermostat, and water pump. But scared to overheat the motor?

Thanks

I like this website, I think I am going to order one from here, unless the one on eBay is less than $30?

This throttle linkage is way out of whack. The first tooth of the horizontal gear must align with the first tooth of the vertical gear. Tilt the tiller handle all the way up. Using a flat blade screwdriver, pry the throttle shaft forward enough to undo the horizontal gear from the aft end of the shaft. Reset the horizontal gear onto the vertical gear so all the teeth align. Slide the horizontal shaft back into the gear, realigning it with the new position AND turning the tiller grip so that the ball gears on the tiller align with those on the fore end of the throttle shaft. The throttle shaft has TWO flats on it. One aligns with the gear, the other aligns with the retaining screw (missing in the photo). Make sure the throttle shaft is firmly seated and the ball gears are aligned properly before lowering the tiller handle, or the cast ball teeth WILL break off.

What years will fit this outboad? It is a 1967, so what other years parts can I look on eBay and CL's for? I can't find an answer using google or iBoats.

 

[Chinewalker]

I believe 1967 was the last year of the small carb motors, so pretty much most parts from 1961 to 1967 will fit. Many parts from 1968 & up will work, too, but less so than '67 & prior... I believe Marine Engine dot com has parts listings back that far for reference.

I looked them up, they don't have the 1967 Evinrude listed. They have the 20HP Johnson, but no 1967 Evinrude 18HP listed. There is the 1966 18HP and the 1968 18 HP.

It's confusing, I actually have looked it up before asking. From what you say, I am going to look at 1966 parts list and see how it goes.

Thanks

 

[Chinewalker]

95% of the 1967 Johnson 20 parts are identical to the Evinrude 18 parts.

Thanks,

Do you know anything about the thermostat? How long till it opens, roughly, so that it will start to spit water? I want it to warm up, but don't want to overheat the engine trying to see if the water pump and thermostat works right.

Thanks

 

[Chinewalker]

Water should flow out within the first 10 seconds of motor start-up. Not all the water runs through the thermostat. Some water will always be flowing through the motor, regardless of whether the thermostat is open or not. Make sure the lower leg is buried well above the bulge that houses the water pump at the base of the exhaust housing. The water pump is not self-priming and needs to be submerged to start pumping. Also, as a matter of course, it is ALWAYS a good idea to replace the impeller on a motor that is new to you unless the previous owner documents it as having been done recently.
