1977 Evinrude Wiring

Re: 1977 Evinrude Wiring

I went down to vatozone and got me some bolts for the stator and put everything back together. I go to crank it and the damn gear on the end of the starter is the wrong size. It's too big for the flywheel so it just grinds the bottom side of the flywheel. The guy I got the boat from told me that was the starter for the engine. It's brand new so maybe I'll be lucky enough to just exchange it. If not, is it possible to just replace the gear on the end of the starter?

You have the website for the parts and their numbers; check them out.

www.marineparts.com has all that stuff and a catalog that gives you the interchange info. Look it up.

P.S.

How did you get hung with that P.O.S.?

Don't ask. A guy here in town had this boat sitting around. He replaced the transom and some other stuff. Long story short, I wanted another trailer and I hit him up about the trailer and he told me that he would sell me the boat, motor and trailer for $200. He was hurting for cash so I figured I would take the whole thing. I figured I'll get it all running and put back to together and try to sell it. I actually have another boat that I was in the middle of restoring when I came across this one. I'm about tired of messing with it now though.

My $.02 worth, complete the dismantle and get an ebay account. You'll come out of the deal with the trailer and money in your pocket. Take what the deal gives you; throwing good $ after bad is a sure loser.

Re: 1977 Evinrude Wiring

Actually I only have $100 in parts for the engine. Got the stator off a used motor for 60 and the rectifier for 40. I went back out there this morning and swap starters with him. Got back home put the starter on and started it up. Here's my next question. I have good compression, spark and I have gas but I can't keep it running without keeping fuel fed to the carburetor or in the cyclinders. What do you'll think? Fuel pump or carburetors? I guess the carburetors work a little different on these engines. I was thinking it was like a car carburetor where you could throttle it and see the gas pumping down. Anyways, input is always appreciated.

Re: 1977 Evinrude Wiring

You can buy a can of carburetor dip & clean the carbs yourself. Be sure & dismantle in a place where small parts won't be lost forever.

The carbs are cleaned and bowls are filling like they should. I can choke it and stick my hand over the carbs while cranking it and my hand has gas on it. What is the mix ratio on these engines? Right now I have it mixed 50:1. I'm stuck now. I can pull my plugs after cranking it for a couple of seconds and they have gas on them. I also took the plugs out and made sure they firing when I crank it over. Anything I might be missing?

What is the compression?

If the compression is good and you have fuel in the cylinders, now you have to throw more dollars at it. Power pack? coils? stator? etc. Now is where you need the manual and some diagnostic devices.

Now might be the time to see what you can buy a 1977 for and balance that against what you will have in this Waukegan anchor.

Re: 1977 Evinrude Wiring

Actually as funny as this sounds I think it is the timing but I'm not real sure how to adjust the timing on a boat. It backfires so that hints something in the timing but like I said I'm not sure how to adjust it. I have a manual so I guess I'm fixing to dig into it. Thanks for the help and if you have any other suggestion speak your mind.

Re: 1977 Evinrude Wiring

Ok, well my timing is off. I think the manual I have is not really specific to this engine. Does anyone else know where a manual is on timing or know how to set the timing? I guess what is confusing me is there is not distributor and I can't see how to set it. I would figure if you had #1 TDC there would be some points or something to line up. Someone else chime in and tell me how to do this in Lehman's terms.

Re: 1977 Evinrude Wiring

If it's backfiring, chances are you've got one of your coils hooked in to either your power pack, or plugs incorrectly. Timing isn't really adjustable in the same way as a car. If you have instructions for a link and sync and follow them to a tee, your timing will be dead on. Double check your coil wiring, that's probably where your problem lies.

Re: 1977 Evinrude Wiring

No my wiring is correct. I've been over it about 4 times. Spark plug wires are on correctly. The timer base and everything moves freely. I was reading up on some of the other questions asked and I thought it might be the flywheel not being lined up on the key correctly. I had to take it off to put a new stator on but it's lined up. If I pull the number 1 plug and run the piston to TDC, where should my timing marks be set? I know the engine need to be 28 degrees advanced. Anyone?

Who's Lehman? Does he post here?

Perhaps Joe Reeves' instructions in this thread will help:

Used Factory Service Manuals are real easy to find and not at all expensive. One screw-up, and you will spend lots more:

Re: 1977 Evinrude Wiring

If I get some time tonight I'll PM you with more link and sync instructions if this doesn't help. My big gripe with the '77 manual is that the link and sync is scattered among several sections. You do a lot of page hopping. I much prefer the later ones where the full link and sync procedure is all in one spot.

Here's the low-speed instructions though.

"Adjust throttle cam as described on page 3-11, section 3. Connect a timing light to #1 cylinder. Start motor and advance control box lever to show 3-5degrees advance timing on 85, or 0-3degrees on 115. See figures 4-26 and 4-29. Stp motor and adjust center of throttle cam roller. See Figure 4-27.

[some WOT adjustments]

With timing light still connected, start motor and check timing as described on page 4-4, Step 4. ADJUST IDLE ADJUSTMENT SCREW SO MOTOR WILL IDLE AT 650 RPM MAXIMUM IN GEAR."


Now, here's page 4-4 Step 4 in summary (this assumes you've set the TDC marker as on page 4-16):
1. Make initial adjustment of full advance stop screw per diagram (diagram shows 5/8" of thread on screw exposed). This is just an initial setting.

2. Timing light on #1 start and set to 4300 to 4600 in gear. 28-degree mark (115) or 26-degree mark(85) on flywheel must align with pointer.

3. Adjust stop adjustment screw as necessary.

Re: 1977 Evinrude Wiring

The manual I have is from promanuals.net. I'm not really happy with it because it deals more with lower HP engines. Anyways, here is where the timing is set right now. I did notice that even at WOT the butterflies in the carbs are barely open. Look at these pics and see what you'll think. Thanks.

Re: 1977 Evinrude Wiring

If the carbs are barely open at WOT, then something is out of whack in the link & sync. From the pics I can't tell what that is though. I'll look a bit harder.

Re: 1977 Evinrude Wiring

I think your problem is this piece is upside down. I'm just going off of memory though, so check the diagrams you have in the manual.
