old sears outboard

[kpk]

Hi,<br />I recently bought an old sears and roebuck 8 hp outboard at a barn sale. It will need to be cleaned up but it isn't seized and I plan on running it. However, I don't have the manual and I might need some parts. Any idea where I can get a manual and parts? The serial number is 641.4623 and the model number is 571.58641.<br /> <br />I was also curious to know how old it is.<br /> <br />One more thing, I assume it is a 2 stroke. What fuel to oil ratio should I use?<br /> <br />-Kris

Re: old sears outboard

You have a 51 6hp.It was built by West Bend for Sears.West Bend was purchased by Chrysler circa 1965 and became Force circa 1985.Fuel mix is 1/2 pint to a gallon.Use TCW3 rated oil.<br />Parts will be hard to find.You could try at www.aomci.org or watch ebay parts and parts motors appear regularly.As far as a manual try ebay for an an aftermarket manual that covers many brands.West didn't sell domestic motors until the mid 50s but Elgin or West Bend information should serve.

Well I just got around to checking the old outboard out. I did a quick triage so I don't waste too much time with something that won't work. The Wico magnetos look to be in bad shape. The outer black insulation is all cracked and falling off. How do I test these to see if they are ok? Also, if they are bad, where can I find replacement ones?

Can't tell you how to check coils but if they are cracked and flaking its time to replace them.<br /> You should also figure to replace the impeller.<br /> Check the sites posted above for parts.

The impellar seems to be in good condition. I pulled it out and it is flexible. Although one of the fins has a "set" to it where it was compressed for a period of time. The rest are good though.
