Need help Id'ying older Evinrude

[tycooper]

I picked up an Evinrude outboard that I thought was a 25 HP but I would like to confirm the HP and Year. Here is the SN: 25022-18690. Does any one know for sure what this is? I put a photo of the hood if it helps.

The Cowl has the colour scheme and script of the 1957 models. However there was no 25 hp in 1957. The 25022 puts it as a 1956 30hp

Yep, 25022 is a 1956 30hp. Either the hood or the serial number plate has been swapped. Look at the cylinder head. A 1957 (35hp) has compression relief valves next to the spark plugs.

OK, thanks for the input. I think it is the 1956 30 HP according to the SN. It does have compression relief on the head.

A 1956 30hp does NOT have a compression relief on the head, making yours most likely a 35hp with a 30hp clamp bracket/serial plate. The serial/model number should also be on a small disc on the cylinder block.
