Old Johnson Identification

Hi

I am looking at buying a used boat that had a 150 Johnson Fast Strike on it. However, the guy blew that powerhead and apparently a 175 USED powerhead was put on as a replacement. The guy has no idea on the year of the powerhead. So if anyone could tell the year from these pictures, that would be great. I tried looking for more serial numbers but couldn't find any with letters at the end.

The engine block is a 1991 thru early production 1993 with the non-adjustable carbs.

What numbers are stamped on the round silver disc on the back of the engine?

Thanks for the reply. The numbers on the plate are 33055646

Are you sure that is the correct number of digits?

On the quarter sized silver plate below the OIS 2000 on the back? Yes I am sure

Hi dbenner,

That number sequence contains too many digits for a proper serial number but if the first character is actually the letter " G " with 3055646 after it, then the powerhead is from a 1992 175 HP Johnson outboard.

Could you provide a well focused close up of the silver plate numbers?

I only had the pictures I took of the block when I went and looked at it, but after zooming in again, it does look like the first character is a G not a 3. The lighting just made it look like a 3. Good knowledge. Thanks!
