"Outboard won't start" is well covered in the Engine FAQs Forum, dodad.

Good luck, and let us know what you find. :)

Internal, or external fuel tank? If external tank, check fuel pump screen. Or fuel pump diaphragm.

Troubleshoot logically. An internal combustion engine needs fuel, air, spark and compression to fire properly. Start with compression and test. Then spark. Then fuel. Let us know what you find. This will save alot of pull rope blisters and cussing.

If you come back and read this, please give us the model number of your outboard. I suspect it's Chrysler-made, but so many people made outboards for Montgomery Ward that we need the model number.

its a 66 6hp seaking model vwb19074a serial 66x11816 i have changed all gaskets so i know its getting good compression it had alot of guk in it i cleaned cause by the time the gas got to the combustion chamber it was black but still wont start so now im gonna clean the magneto even tho i get plenty of fire doing that today and suggestions?

What do you mean by you "changed all gaskets?" All? Every one? What made you do that?

The only way to know what the compression is required a compression gauge. You haven't mentioned the carburetor at all.

See...figuring out why your outboard won't start is a step-by-step process. Before doing anything, you need to know why you are doing that thing. First step is to check compression with a proper gauge. Second step is to check for a strong spark on both cylinders. You said it had good fire. How did you determine that?

If both of those things, compression and spark, are good, then it's time to move on to fuel delivery. You start by spraying some fuel mix (not starting fluid) into the carburetor throat and seeing if it'll fire. If that works, then you need to disassemble and clean your carburetor, making sure every orifice in it is clean and that the float is set properly and the needle and seat are working correctly. A Carburetor kit contains a needle and seat and all other parts you need to do a proper job.

You need to make sure that the fuel is getting to the carburetor, too. You can test the fuel pump by simply disconnecting the hose from it to the carburetor and turning the engine over. Fuel should come out. Sometimes the problem is in your fuel tank or fuel line or bulb.

Once you sort out all of these things, your engine should start and run. Until you have gone through all the steps, in the proper order, as I have described them above and as is described in that FAQ you were aimed at, we'll just be telling to to follow those steps.

I don't work on Chrysler outboards, so I can't give you detailed instructions on that outboard. You can get a service manual for your outboard right here on iboats. It will show you how to do those steps.

We don't have a magic wand here. We can't see your outboard. We have to rely on you telling us everything you have done and everything you've found if we're going to help you.

Re: 6hp seaking wont start please help

i saw how gunked up all the internals were and had to clean it out thats why i replaced most of the gaskets this motor looks to have been sitting sence the 70s from the inside but only other explanation is a sheared key and i dont have a compression gauge so now i know it has to have good compression right

Well the "beating on it" trick never works, and could ruin your flywheel. As I said, I don't work on Chrysler-based outboards. Are there three holes on the flywheel, in a circle near the crankshaft? If so, an automotive harmonic balancer puller is the right tool.

Get a manual. Go to your local library and check out an aftermarket manual that covers your outboard. It will have answers to all of your questions. Even better is an actual factory service manual. You can buy an aftermarket manual here on iboats. It's a lot cheaper than a busted flywheel.

You cannot know what the compression is without a gauge. You can get one cheap at any auto parts store. It will last a lifetime.

I know you're trying to get this outboard running on the cheap, but that trick never works. Unless you do things the right way, you may never get it running, and may ruin it in the process. Your description of how you're trying to remove the flywheel is a good example. Break the flywheel, and you're in deep doodoo.

Do it right or don't bother. That's my advice. You mention the internals. How far did you have this torn down? Are you sure you got it all back together correctly? It sounds to me like you're approaching this whole thing in a haphazard, unplanned way. That will lead you down the wrong path every time.

I have no more advice for you. I've already suggested that you get a manual and buy or borrow a compression gauge. Those are the first steps in resurrecting your old outboard. Parts are scarce for the 6hp models from those early days. Break something and you're going to spend a lot of time trying to find it. Just take this one step at a time. Eliminate each problem, in the order that has been recommended to you. If you do that, you may end up with a working outboard.

Continue as you are, though, and you'll end up spending a lot of wasted time and still won't have a running outboard. Seriously.

Re: 6hp seaking wont start please help

There aren't any published numbers. As I said, I'm not a Chrysler expert. I'd expect that if both cylinders test out at above 70 psi and are nearly the same as each other, the compression will be good enough for that outboard to run.

You can find guides on how to check compression by searching here on iboats. If you follow them, you'll get a good reading. You need a gauge that screws into the plug holes, since you can't hold a gauge and pull the rope at the same time. At least five pulls on each cylinder.
