Serial number 30822 makes it an early 1926 model. The models built that year were the A-25, a two horse power twin - The AB-25, same outboard except with a canoe bracket instead of a transom bracket. The J-25, a horse and a half horse power single - and the P-30, a six horse power twin. Johnson sold 14,471 motors that year. That is all I have . . .
