1963 40 hp evinrude timing/help questions

[xtremefisher1]

i seen the other thread about his 33 hp rude but i have a few question when you rotate the stator plate do you loosen all 4 screws off and rotate it so it hits the stop? or do you just loosen 2 off and rotate the plate?

also my roller cam doesnt even touch the cam plate when at wot. is there something i am missing here? at wot does the plate not lay completely open or for these is it just partially open?

thanks guys

No, you don't loosen the hold down screws at all. No need to even remove the flywheel for this adjustment. There is a little Collar with a screw in it (at least there should be) Items 16 and 17 on the diagram below and they are on the Throttle Control Rod item 18. Turn your throttle lever till you see the mark on the cam plate centered on the mark on the engine block. Once you get it centered, then loosen the screw and collar and slide them all the way toward where the Pivot Pin (item 15)attaches to the Lever. With the motor in forward gear and the throttle advanced, the throttle should be wide open.

Re: 1963 40 hp evinrude timing/help questions

what about the stop arm and the stop under the the flywheel? mine didnt touch the stop on the block. how would i adjust that or is that for only the ideal cruise stop?

Re: 1963 40 hp evinrude timing/help questions

You'll need to put the motor in forward gear to get the stop to touch.

Re: 1963 40 hp evinrude timing/help questions

what do i need to do to get it to touch? also what can i do to tighten everything up ? from the linkage on the side of the motor all the way to the stop? everything seems loose due to age and wear .

Re: 1963 40 hp evinrude timing/help questions

When you put it in gear, just twist the throttle indicator all the way left to the "Fast" position. If everything turns hard, then you likely need to remove some parts to it and clean and relube them.

k sounds good . also another question is where does the water come in from the intake part of the leg? i have absolutely no water coming out so i need to do the impeller but would like to know where the actuall inlet is for this motor

Re: 1963 40 hp evinrude timing/help questions

I would remove the thermostat and run it with the cap off to see if water comes pumping up there. The thermostat is under that little triangle shape lid on top of the cylinder head and it's held down with three slothead screws. If you don't see water gushing out of there after about 3 to 4 seconds, then it's safe to say that your impeller is shot. It would be a good idea to replace it anyway, just to give you good piece of mind, but you can at least check now and see if you have good water flow.

Re: 1963 40 hp evinrude timing/help questions

ya i already did that and the impeller is shot to hell!!

Re: 1963 40 hp evinrude timing/help questions

Yea, I have three of these motors that need impellers LOL A '58, '61, and a '62.

1946 Zephyr is a friend of mine and I totally respect him, but he got it wrong. (Sorry 'bout that)

The carb roller and the throttle rod adjustment are two entirely separate items.

With the motor in forward gear, advance the armature plate as far as it will go, arm up against the stop on top of the block. At that point, the set collar should be just a hair short of contacting the pin in the throttle lever. Further movement of the throttle control pushes on the set collar, moving the rod to kick the carburetor butterfly wide open. Yes, the roller will be way off the cam at that time. And the pin should NOT push on the rod until the armature plate is at full advance position, up against the stop block (in gear).

As for the roller pick-up point on the brass cam, advance the armature plate till the mark on the cam aligns with the pointer on the intake manifold (NOT the roller). When it aligns, the roller should just be ready to start opening the carb butterfly. The cam NEVER opens the butterfly all the way---the set collar & rod does that.

As I said previouosly, these are the most screwed up adjustments on those motors. Once in awhile, you will actually see one that is correct.

Re: 1963 40 hp evinrude timing/help questions

Thanks F_R You're a good friend of mine too. I might check mine over too and make sure they're right. I've been lucky so far and haven't had to mess with that.

Re: 1963 40 hp evinrude timing/help questions

ok thanks for the help i think i have it setup that way already.. hopefully anyways lol .. now for a carb question . i have the 33hp carb and the 40 hp carb. the 33 has the 2 adjustments and the 40 has just the low speed with a set high speed.

what i want to do is change the carb cuz i really hate that stupid stuff on the side of mine now. since the high speed is fixed and the high speed on the 33 is variable cant i just switch the jets on the carbs? i would put the high speed from the 40 hp in where the high speed variable on the 33hp would be????

Re: 1963 40 hp evinrude timing/help questions

Those carbs are quite a lot different. It's not likely to work, unless you changed the whole carb. You can bolt it up and try it.

Re: 1963 40 hp evinrude timing/help questions

Agreed. I suppose you are objecting to that automatic choke. I don't like them either, because they never work. But to answer your specific question, no you can't just swap the jetting system. You would have to swap the carb bowl also. Then that presents a new problem: The choke won't hook up.

I suppose you could swap the whole carb, but may lose a horse along the way. I've never tried it.

Re: 1963 40 hp evinrude timing/help questions

If I'm not mistaken, The 33 used a type I carb and the single jet screw carb on the 40 was a type II. Maybe vice versa. I need to dig out my manuals again. I guess tomorrow, I'll be able to see when the 40 was changed to the single jet screw, because I have a '61 and a '62 here now. I know both of mine have the automatic chokes. A lot of changes in the powerhead in '62 though, that I do know. From what I see, the automatic chokes were operated by water temperature coming from the block, midway toward the head. I can see why they might be an issue, because typically, these big twins, don't really need the choke, once they fire up, which is nice about the electric solenoid choke. The water temp controlled choke opens up, when the water temp warms up, which by then, these big twins are running way rich and fouling out plugs, faster than you can buy them. I have actually heard someone say though, that they work good. It's just a matter of adjusting them, to open up, within 3 seconds after the motor fires up.

Re: 1963 40 hp evinrude timing/help questions

I'd like to chime in regarding the throttle collar adjustment. On my 33hp, I adjusted this the way FR has described, by advancing to full spark and adjusting the collar to 1/32" clearance from the pin. The problem I'm having is once I set this adjustment, my carb butterfly will not fully open when I go to full throttle. The only way I can get my carb to fully open is by moving the collar which would render it out of proper adjustment. Any idea?

Re: 1963 40 hp evinrude timing/help questions

the carbs seem to have the identical carb kit from what i can find on iboats and other sources. also i know from my book i got from the library that there is supose to be a meatl tube coming from the side of the motor to that stupid choke but i dont have that all i have is hoses running all over my engine i will take some pics and show you guys what i am talking about.

i cant seem to find the carb kit with the choke rebuild kit in unless thats a totally different kit. also i tore apart my 33 carb last night when i got home at 1 am from work to find out that its all gummed up and everything was just a mess inside. so a rebuild kit will be ordered. i can just imagine what the inside of my 40 carb looks like since my 40 was a older motor.

if someone knows the exact part number for the 40 hp carb that has that stupid choke rebuild kit that would be great cuz i cant find any.

its 1963 40 hp 40353d

if someone has a better book than i do . if they could find out the specs on both carbs for me that would be awesome cuz i dont know and i have looked around for awhile and cant find any info


thanks guys

Re: 1963 40 hp evinrude timing/help questions

k guys heres the pictures of the stupid setup i have for a choke

Re: 1963 40 hp evinrude timing/help questions











as you can see from the pictures i dont have that metal tube coming down the side for the choke
