Ok, so today we went on a venture to look at a "few" motors. It has been an uneventful year thus far, 2 washers died, dryer died, furnace died, van died, then got laid off to boot. So back to the questions at hand heh.

We managed to pick up 6 motors and 2 trollers today for $125, not a bad start i hope. Out of them there was a clinton (unknown HP) an Eska 5.1 CI, Ted Williams 3hp, Ted Williams 5hp, Ted Williams 7.5hp And a mercury 5hp. They are all around early late 70's except the merc which im thinking more of a 60's. the trollers were nothing special, so wont even mention them ^^.

I spent a few hours fiddling with them, changed out gas, checked plus and for spark and all the normal things. The Clinton is pretty much for parts i guess, the tank is rusted out, they put an external feed on it, and i did not bother to test it nor the 7.5hp. The Eska, Clinton, and two smaller Ted Williams all have similar lower units, and will interchance at the motor, so I know they are from the same manufacture. The Ted Williams and Eska have Tecumseh motors for sure.

Now out of the 6 thus far, I managed to get the 5hp TW to fire and run, ran it for 4 or 5 minutes til warm, but could not restart it, it seems as though the float is out of adjustment, leaking fuel out of the intake end of the carb, so its overfueling. The 3hp TW seems to have no compression, so have not fiddled with it anymore as yet. The question here though, is the carb interchangeable between the 3hp and 5hp TW engines? Being Tecumseh's I am sure I can re-ring the 3hp, but given its great source of parts for the 5hp, if the carb will resolve the issue and get the 5hp running then awesome, we have another motor and parts to spare.

The Eska 5.1ci, I cannot seem to find any information on. It looks like a lawnmower engine cowling, in a wonderful orange color haha. A touch of ether, and fresh gas, now can be started by my 9year old daughter in half a pull. I am stoked it runs so great, put it on the boat and took the kids for a little cruise. However, I cannot seem to determine the HP rating on this engine?? It's a 5.1cu Tecumseh, I am guessing 3 or 3.5hp? It's no racer ^^ but cruises the lake beautifully.

The other motors I will be tearing into tomorrow, I would love to see the 7.5hp run, and the Merc, seeing as my associate and I have both been laid off, we are hoping this small investment will put motors on both our boats, and hopefully replace the cost we paid and then some. Wife told me, I been laid off, cannot seem to find employment, best to get resourcefull and try and turn any profit no matter how small ^^

And for my Johnson Seahorse HD25 in my other post, its still not running, I got hot spark both cylinders now, but cannot get her to stay running =( "IF" I keep pumping the primer it will run but nothing special. So maybe carb is out of adjustment, havnt gotten into it any further yet. I have a possible trade for the work on it versus my parts HD25, so contemplating this as a means to getting it running.

Anyhow, I have written a book, really just wanted to share and put it all up for critisim, hoping spmeone can lead me to if the TW 3hp and 5hp can interchange on the carb. And hopefully what exactly the lil 5.1ci Eska is. Posting a pick of the Eska on the back of the "nasty" boat as my daughter stated when I brpought it home haha, a LOT of work went into her but shes a great lil fishin boat now =)

Take care peoples

Re: Eska 5.1 CI

well as far as the tw i believe that the carbs from 3-7.5hp are almost all compatible but don't quote me on that.you can find some parts for those but the electrical stuff is really rare and difficult to find and i think ebay will be the only place to find anything like that if its even available.also by putting up mode l#'s it will help us help you with info needed...there's a lot of helpful people here with knowledge on that kind of stuff but without model # info is limited....good luck

The Tecumseh motors haven't much changed over the years. The ignition parts should be readily available at the mower shop. As far as I know, the most modern points & condenser from the newer Tecumseh 2 strokes will fit in the Tecumsehs from the 60's - 70's. Coils are getting pricey.

Carbs are difficult to find, however the rebuild kits are available.

Good Luck. I've got an Eska Blue Jet from the early 1960's that I've been running since 1978 when I bought it used. It's not real pretty, but then the last 30 years haven't been so appealing on my features either. Heh heh.

The 5.1 is a Tecumseh V51 power head.It was used for 3,4 and 5 hp motors.
Came with a J13Y champion plug set at .030.
Eska also used a Clinton 501 5.76 for a 5hp I believe in 64,65Clinton uses a Tillotson carb the Eska uses a Powerproducts/Tecumseh carb.
V51 first appeared in 61 as a 4.ran through 65.Also began as a 3 in 64-68,appeared as a 5 in 66,67.

Re: Eska 5.1 CI

Excellent, thanks for the help everyone. Ya that lil orange Eska is no show stopper haha, but 1/2 a pull and she fires right up, cannot pass that kind up!

The Ted Williams, I hope to have the 5hp running tomorrow since its supposed to be 57 out haha, I will try and fire the 3hp again, and if nothing stripping the carn for the 5hp. today is just a touch nippy and we have a lot planned.

The Clinton is parts, I have no real plan for it other than parts, the gas tank is rusted out beyond repair, the rest seems interchangeable with the Eska, so its good source imho.

Hopefully can get the boat registered Monday and take my kids fishing ^^

take care and thanks everyone!

Unfortunately that appears to be the case with them; but part them out.
I hate to see even those problem children go to the trash.At least give them away on craigs list.

Re: Eska 5.1 CI

So far, got the 3hp Eska running like a top, not a worry in my mind at all using it, been out several times, always restarts with 1/2 a pull, tho it needs new pull rope it broke other day, glad wasnt on the lake, other than that will put new plug in it for sake of argument.

the 5hp TW i got running, we took it out and wow, it flew, had my boat nearly on step with 2 of us in it. however once it got warm it idled down a touch, carb is out of adjustment or havnt got the mix right yet, will figure it out tho.

The clinton, got the top end off the 3hp TW, and runs great now, verydependable also.

The 3hp TW i got plans to mount a 5hp Tecumseh/Briggs and Stratton lawnmower engine on, and will have it underway as soon as i get a doaner mower ^^

The mercury, we have great spark, plenty of compression, but it just wont fire. So something is gunked up in the fuel lines or the carb is scraged, none the less its a merc, and im sure parts are fairly easy to find. Its a Mark 5, no idea of year yet hadnt looked into it much.

The 7.5hp TW has great compressiogn, everything looks in order, but no spark, pulled flywheel and havnt looked into it much since, been busy with pontoon boat repairs.

needless to say, i am pleased we have now 3 good running motors, my johnson finally ran, and runs. But i cannot get her into peak rpm range, did manage to go few hundred feet before i decided she wouldnt rev and parked it so i didnt screw anything up.

anyhow, thats a ton for the help, once i et this lawnmower/boat motor going ill get something on here about it too.
