Re: Need help bigtime!!!

<Does anybody know the easiest way to bend that shaft back.>

Find out where local motorcycle shops sent bent fork tubes to be straightened. I used to work at a motorcycle shop where we had a mechanic (trained as a machinist) who straightened forks and pressed crankshafts apart and pressed them back together after installing new bearings. He performed that work for most of the other shops in a wide area and brought a lot of $ into our service dept. I've seen him straighten forks I would have sworn were 'goners' but when he got thru they were as straight as the day they were new and would hardly wiggle a dial indicator when chucked in the lathe.

If you have no luck in the motorcycle shops start stopping in at machine shops.

I believe it would only be the tube itself but I haven't had the thing apart yet to try to figure it out.

The bend is really so very slight that I really don't know if it would be affecting it that much. If you expand the pics I posted earlier in this post you can see that it just barely makes a curve, but it's possible that it's just enough since it's so high on the shaft.

I guess i'll just go tear it apart and it I can't get it fixed i'll just sell it for parts or something.

Sorry to plague you guys with so many newbee ?'s. I haven't ever done any work on an outboard before so this will be an experience in itself. I love these kinds of challenges though so it will be fun.

I am actually taking some college courses here at the local college and they have a machine shop there. Maybe I can get one of the guys there to try. Thanks for the suggestion Tom @ Buzzard Bluff.

It appears from the pics that the bend is immediately below the lower pivot clamp. It will definitely affect it! Even if the shaft itself proves to still be straight the bent tube creates a misalignment between the crankshaft and the lower unit that will trash one or both very quickly! If the shaft is bent also then you can pick your own multiplier for 'very quickly'!
The lower crank bearing is most probably a ball bearing but You can almost bet that the upper driveshaft bearing in the lower unit is nothing more durable than a bronze sleeve bearing. With any side load such as will be imposed by mislaignment of driveshaft OR tube that bearing will be toast. In fact if the driveshaft is straight I would go so far as to suggest replacement of the tube that is bent with a new part.

Where are you located?

Careful! I got infected with the old outboard disease merely by deciding I owed a '62 3 horse Evinrude a tune-up after @ 20 years of dependable service!
I learn something new nearly every day. Today I finally got a motor cranking and running sweetly that has been frustrating me off & on for the past 5-6 years. It was all the sweeter for that!

I am in Groveland, Il. That's close to Peoria, IL if you've heard of it.

Tom, are you saying that it might just be as simple as to repair or replace that shaft (and or tube) and maybe a bearing or so?

That would be amazing.

I just can't see not taking the time to at least investigate it when the motor runs so smoothly. It doesn't even shake like I keep reading all these other people telling me the Eska's are famous for.

Should I start from the top or the bottom to tear it apart?

<Tom, are you saying that it might just be as simple as to repair or replace that shaft (and or tube) and maybe a bearing or so?>

Almost certainly. If it hasn't been run much in the condition it is in then the bearings may still be good.

<I just can't see not taking the time to at least investigate it when the motor runs so smoothly. It doesn't even shake like I keep reading all these other people telling me the Eska's are famous for.>

The vast majority of the Eskas use a much bigger single cylinder engine than does your Eska/Tanaka. The smallest Tecumseh engine on Eskas that I can recall at the moment is 5.1 cu.in. The bulk of Eska production then ranged from 5.1 cid thru almost 9 cid. Big singles DO vibrate! Reciprocating mass of the big singles was a far greater factor then than the comparatively tiny amount of fast moving metal in your motor.
Some find the vibration much more disconcerting than others. My 7.5 Eska certainly vibrates MUCH more than my 3 horse Lightwin but I enjoy both of them------and far too many others.

<Should I start from the top or the bottom to tear it apart?>

Never worked on that model but bottom up is normal practice. Just take your time and work LOGICALLY! Now would be the time to have the shop manual in hand. It will repay you many times.

Re: Need help bigtime!!!

Do you know of anyplace that I can find an ACTUAL shop manual, not just an in general repair guide for ones that are close to mine?

All I seem to be able to find is the owners manual and the general stuff you guys sent to me earlier. None of which seem to match what i am looking at.

They are close but I don't think they're close enough.

Do you think it'd be worth it to take to a local shop and try to get a free stimate on repair?

Re: Need help bigtime!!!

Some things I've neglected to mention:

Now would be a good time to contact the customer service dept. at Tanaka USA with your model & serial #s by either phone or e-mail. Tell them that you need to know which of the illustrated parts breakdowns and part # list applies to your motor since you will be making up a list of parts to order from them. And go ahead and get the applicable shop manual on order!

That illustrated breakdown--once you are certain which one applies---will be your guide for disassembly. Examine it closely before each step before picking up a wrench or screwdriver. The pics and the logical process I mentioned before should see you thru. Even tho I've been tinkering with old motors for almost a decade and am fairly familiar with them I would be reluctant to start on one without a manual---it always saves me $ in some area!

At the top of your parts list go ahead and write in 'driveshaft seal' & 'propshaft seal'. They are rubber parts that at this point can be no less than 24 years old. Even if they're still good at this time (& I doubt the driveshaft seal can be since you've ran the motor---BTW---just how much run time HAVE you put on it?) then it's a cinch that they won't be much longer and it would verge on criminally stupid () to pull down the lower end as far as will be necessary without replacing them.

There may be other seals and there's sure to be some form of fuel line from tank to carb. Now would be a good time to refresh ALL 'soft' parts.

I'm outta here---got things to do in the shop.

Have you asked Tanaka US about a shop manual yet? If they don't have it then you are stuck with the aftermarket manuals. I use the Intertec series and they are surprisingly good in most cases.

<Do you think it'd be worth it to take to a local shop and try to get a free stimate on repair?>

Not a chance! The odds of finding a shop that will touch an Eska--much less one from Tanaka--are infinitesimal and the $75-$80 shop rates for the research we have helped you with for nothing would be brutal. Just find the best manual you can, roll up your sleeves and THINK before each operation!

Re: Need help bigtime!!!

Thanks everybody! Sorry it took me so long to respond. Wife and daughter both were in hospital and the motorcycle broke down so that all took presedence. I'll keep you informed of my progress.

No problem with response time! Sure hope the wife, daughter and motorcycle (in that order!) are ALL doing better!!!
I too come and go according to what is happening in 'real life'.

Please do come back to tell us how you fared with your motor. Success stories always boost our egos and fire up our willingness to help others. Should you encounter problems don't hesitate to ask for guidance. Even tho I (& apparently everyone else judging by lack of concrete commentary) have never encountered that particular motor someone will always be along to offer general advice. Good luck! Tom

Re: Need help bigtime!!!

Be patient and keep an eye out on CL and other sites...prowl the boat bone yards...Eska's are common and generally cheap. Bet you can find one with a good lower end but bad powerhead for less $$ and effort than you would spend on parts...unless the parts are dirt cheap.

here you go,

http://cgi.ebay.com/ebaymotors/ESKA-2-0-OUTBOARD-BOAT-MOTOR-RUNS-GREAT-/120582798772?cmd=ViewItem&pt=Boat_Parts_Accessories_Gear&hash=item1c134b7db4

Up for Auction is a Eska 2.0 Horsepower Outboard Boat Motor. Item has been stored in the garage for several years. Model # 14205 A. Serial # 38-362369. Two Stroke, Air Cooled. Requires a 25 to 1 Gas / Oil Mixture. Self-contained Fuel Tank. Motor Spins 180 Degrees for Reverse. Item is in Good Condition and Runs Great. Cosmetic Condition is also Very Good. There is one issue with this item: There is a plastic collar that clamps around the shaft. This collar allows the motor to lock down to the motor mounting bracket when using the motor in reverse, (so the lower end wont lift up out of the water when in reverse). The plastic collar is cracked, it does function now, but might have problems in the future. It could be replaced, glued or re-fabed with a hose clamp and small piece of aluminum or metal angle iron. There is a picture of the cracked piece in question. Handle will be removed and packed with item for shipping. Fuel tank will also be empty and fuel valve shut off for shipping purposes. Please don?t forget to add 2 cycle oil to your gas! Payment by Paypal would be Great. Shipping for this item will be a Flat $25.00 for UPS Ground. USA Only. Thanks and Good Luck.
