Arrow air cooled outboard info?

[thephridge]

I have an Arrow air cooled outboard. Serial number 690570. Can anyone help with narrowing down the horse power?

Thanks.

Is there no Model number anywhere?

Here’s a listing of models and a little bit about the company that made them.

Posting a picture would help.

I only have the power head and recoil and the transom mounting part. I can’t see a model number. I checked discount parts sight and didn’t find anything there. I’ve attached an image of the power head. Its not a great picture. Is there anyway from the power head I can tell the HP?

Here’s the other page on discount marine parts that gives the over-view.

From the picture I wonder if that is a tecumseh powerhead? Tecumseh made powerheads and sold them to various outboard manufacturers. If so; then you can look over the powerhead and maybe you will find a Tecumseh model number. Then you can look that up and see the HP. Look for numbers punched into the blower housing or for a small tag mounted on the engine somewhere,

So everything has petered out. The only other number I can find is on the flywheel…610751. And that only comes up as a part number. There has to be a way to find the HP of this motor.

If you can measure bore and stroke and find “specs”, then you’ll know horse power.

Prepare to be boarded!
