Re: OTASCO Engine

The Flying O was a private label built by Eska.They appeared in 68 and 69
5 hp Eska procedures should serve you well.
Motors used a air cooled Tecumserh powerhead with a water cooled leg.
68 used an AV520 power head and 69 used AV 600.
Many private labels were supplied by Eska.
There is pretty strong Eska support here in other outboards.

Re: OTASCO Engine

1908-B comes out as a 1974 AV-600 5 hp built by eska, the powerhead is tecumseh AV-600 and they are pretty easy to work on. before you get too involved into the engine make sure you do a spark and compression test, if you have both then your in luck and in the right place for people to help you on your way of getting it running again.

Re: OTASCO Engine

Well good news, my son and I got it running, a little ruff but still runs. He set the points at 18 degrees and it seems to run ok, we think the carb. needs rebuilding but other then that seems ok. I do have a question how do we know if the water pump is working? I believe it is air cooled but also has a water pump. Thanks again for all your input and info. Fills good to get something like this running again, we found it at a dump, someone just tossed it out.

Re: OTASCO Engine

there should be some exhaust relief holes in the leg and you should get a spray or mist.
It would be interersting to see if your outboard uses a Eska leg and pump and we might be able to point you in the right direction for that part.

Re: OTASCO Engine

Well could be bad news, a very small amount of water came out the relief holes and then nothing, can feel exhaust but no mist.
Thanks again for your info. it has helped

Re: OTASCO Engine

darned old rubber parts, after 40 years they tend to fall apart

 

[jaw1956]

Re: OTASCO Engine

I thought that might be the problem, can you tell me what to remove to check (replace) the rubber parts.
And down the road I'll need a prop for it, if we can get it all running again

Re: OTASCO Engine

You need to drop the foot, 1 bolt 1 nut....clean the drive shaft then remove the water pump housing, 2 screws....find out what size impeller, long or short. check with these people for props and parts. And its a good idea to replace all the seals while your in there.

Re: OTASCO Engine

Just to clear up any confusion 2 fasteners one bolt and one nut.

 

[mrcrabs]

Re: OTASCO Engine

one bolt and one nut

and one washer, And not to forget the stainless steel plate covering said nut and washer

 

[jaw1956]

Re: OTASCO Engine

Ok I will keep track of all fasteners, bolt, nut and washer, also stainless steel plate.
We are going to work on it this weekend, no big hurry, most lakes here in Texas are so low you can almost walk across them.
We will let you know what we find once we get into it, more to follow.

Re: OTASCO Engine

Well an update, impeller is shot, mrcrabs said (It would be interersting to see if your outboard uses a Eska leg and pump) not sure what that would look like, also removed carb, looks good inside.
So now we need an impeller, and a carb. rebuild kit. "the carb. is a Lauson Power Products, Grafton, Wis." Boy will be nice to get this going again.
Thanks

Re: OTASCO Engine
