TOPIC: Found a neat little Evinrude

Anyone know anything about this? The PO thinks he got it sometime in the 70's. It runs on four D cells.
I know it's a toy...or memorabilia if you will but you guys really know boat stuff so here it is.

looks like a vintage K&O....usually go for big bucks...john

Thanks. With that info I was able to find a website about them, this one is a 1957 35HP Big Twin. As vintage K&O motors go, this one is very common.

If it works it will start at $145.00

It works perfectly, had it on the boat and running in my little pond just a few days ago. I should probably sell it and buy the parts my real boat motor needs.
