1965 Evinrude 18hp has no holes in flywheel.

[monriverguy]

Hello to all, This is my first post on here and i thank everyone for there help upfront. I have a 1965 18hp fast twin evinrude motor that i got about 15 years ago. the engine ran good when i got it and i used it for about 3 yrs. It has sat in my basement for the last 12 years and i got it out last week and want to try to get it running again. It is in pretty good shape and i tried to start it with new gas and oil but no luck. Got a spark tester and no spark so as i have read here i need a rebuild of coils, points and so on.. My problem is i got down to the flywheel but have no holes in it to use a puller like is shown is this forum. Any help PLEASE?

Thanks
John

Quite a few of the engines in that hp range had a cover attached to the flywheel by the flywheel nut. This covered those threaded holes. If those holes aren't there... that would be a first in my book.

Re: 1965 Evinrude 18hp has no holes in flywheel.

You likely have to remove the flywheel nut and the collar underneath.. that collar covers the puller holes. At least there should be 3 puller holes there.

Welcome aboard, and good luck!

Hi monriverguy. Welcome to iboats. You have to remove the pull starter to access the flywheel nut and puller bolt holes. You'll then need 3, 1/4 x 20 GRADE 8 bolts and washers to use with the puller as the stock bolts are not strong enough. Here are some links that can walk you through a tune up from top to bottom. You can get any parts you may need for the job right here at iboats.

Re: 1965 Evinrude 18hp has no holes in flywheel.

Wow thanks all , You all was right once i took of the flywheel nut and what i thought was a big washer there was the holes. I went out got a puller at sears and wola the fly wheel is off. Now here is the question every thing looks good in there no cracks in the coil, can this go bad just sitting? i thought i would have more trouble with the carb then spark.
as i said this engine ran well when it was put away 12 yrs ago the basement it a bit damp but had it coverd.

and thanks again all i will keep you posted on this as i need your help...

Most likely you have dirt or corrosion on your points.Give the points a very light sanding with a points file or a very fine piece of sandpaper. Dip a clean white business card in a solvent like lacquer thinner and pull it through the points and then blow them with compressed air. Set them to 0.020" gap and give them a try.

You don't need to torque the flywheel down to its maximum torque just to test for spark. Put the flywheel nut on very tight, by hand and do your spark test. The flywheel will be fine that way as long as you don't go and start it up. Torque it to spec before you run the motor.

Re: 1965 Evinrude 18hp has no holes in flywheel.

I am going to try that first. cant wait to get home and work on it again.. i will try and post some pics too

THANK YOU ALL again i really love this motor and this site!!!!

Re: 1965 Evinrude 18hp has no holes in flywheel.

(Point Setting Of Magneto Models)
(J. Reeves)

Set the points as follows. Have the flywheel key aligned with the fiber rubbing portion of the ignition points. Adjust the gap so that a .020 gauge will pass thru but a .022 will not. Should there be any question of the points being dirty (touching the contact with your finger would cause them to be dirty), clean them with a small brush and acetone or lacquer thinner.

NOTE 1: Should the operating cam have a small portion on it with the word "SET" imprinted, align this portion with the fiber rubbing portion instead of the flywheel key.

NOTE 2: Should the cam have the word TOP embossed on the top of it, that is a cam that could be installed upside down and this is simply telling you which side is up. It is not a position where one would set the points.

Not professional videos, but they can help guide you through ignition diagnostics and repair. The motor in the video is a 1968 Johnson 6hp.

I posted this to help another member, it may help you with the ignition.


Well, after having camera issues and having to use an older video recorder, I finally finished the video. The video was an 1hr and 7 min long, but I had to break up the video into 10 min segment to place on you tube. I had not originally wanted to put on you tube, but photobucket was acting up.




Hopefully will give you a visual and help you some.

Sorry the camera and video edit software was not all that great. It is very hard to see the spark when I am checking with the spark checker, but in the end I get both set of spark plugs to fire even though you may not be see them. Anyway, I think you will get a good idea how to work on OMC ignition from 1950 to 1973. I know I repeat a lot and videos are a little long, so I had to break each segment into 10 min. I am not that good a videoing or editing.

Hope it helps anyway. Oh, sorry about the caption that the video edit was not activated so it is a little distracting.

Cheers, hope y'all have fun working on old outboards!!!



***[highlight]Oh, by the way, I cleaned the carburetor and connected it to the fuel tank and it started on the 2nd crank!!! It may look old but she will be a runner!!![/highlight]

Re: 1965 Evinrude 18hp has no holes in flywheel.

Thanks for the videos and all the setting points info, i have a question that i just saw in the 1st video, on one of the plug wires past where they where held to the motor there is a tiny metal ring around one of the spark plug wires.. What is it for, Is it necessary...

I am missing mine but do remember seeing that on my motor also....

That metal ring is to help identify which spark plug wire goes to the top cylinder. It is not necessary to have but it is convenient. You can use a piece of color electric tape or whatever to label to the top spark plug wire.

Hope the videos help you!!

Re: 1965 Evinrude 18hp has no holes in flywheel.

Yes. Those wires can usually reach either cylinder and if they get mixed up (top wire to bottom cylinder, etc.) the motor will never run. As Cajun says, a piece of tape will suffice.

Re: 1965 Evinrude 18hp has no holes in flywheel.

+1. A metal clip, or piece of tape is used to simply denote the upper/#1 cylinder.

Re: 1965 Evinrude 18hp has no holes in flywheel.

David,

I thought the videos were great, got my ohm meter in hand and cant wait to get home and test coils and wires like you showed in video.

Thank again for all the quick and helpful reply's to all my questions.

Re: 1965 Evinrude 18hp has no holes in flywheel.

Ok guys here is what i found so far, tested coils last night and one showed signs of bad secondary coil on one, will remove coil completjy to see is its the coil or a bad connection as i tested it thew the spark wire like video showed... Another question for all you out there......


There is 3 wires hooked up to my points one from coil one from condenser, IS the 3rd wire from my kill switch?
My motor is a 1965 evinrude 18 hp 18502s

Thanks again to all

 

[kfa4303]

Re: 1965 Evinrude 18hp has no holes in flywheel.

Hello again mon. Glad you got some spark. Yes, the third wire is from the kill switch. There should be one to each set of points. They connect to the backside of the switch itself. I would suggest swapping the stock switch for one of the lanyard kill switches in the pic below. They only cost about $10 and install in about 5 minutes in the stock location. Not only do they add an extra layer of safety, but they offer a bit of extra security by allowing you to take the lanyard with you at the dock. Not to mention the fact that the red kill switch makes a lot more sense to me than the stock black button.

Re: 1965 Evinrude 18hp has no holes in flywheel.

Ok all i removed coil last night for sure got a bad secondary coil, plus got no reading threw spark plug wire. I want to order new coils and points and just replace all why i am this far into it. Is there a preferred brand i should get? does all the replacements fit good?

And once again i cant thank you all enough for all you advice as this is the first boat motor i have ever worked on and would not have a clue if not for all the great people here on this site

Re: 1965 Evinrude 18hp has no holes in flywheel.

For outboard parts, there are two big competitors. The BRP brand, which is the OEM brand and there is Sierra, which is the aftermarket brand. I have never had any problems with the BRP brand and only the occasional problem with Sierra. Sierra will be cheaper. I would go with BRP. One of my problems with Sierra, in the past, was a faulty point set.

If you have the right part number the parts should work fine.

Re: 1965 Evinrude 18hp has no holes in flywheel.

Below decribes how to align the coils so that they are the proper distance away from the flywheel magnets.

See my other reply above on how to make sure the points are set properly.

(Magneto & Driver Coil Alignment)
(J. Reeves)

To align the coils properly, have the metal vertical portion of the coil yokes aligned with the inside edge of the bevel that exists on the top portion of the aluminum seat upon which the coils sit. This creates the proper distance between the coils and the flywheel magnets. Faulty alignment creates friction and the yokes of the coils heat up, turn blue and expand.
