30hp Johnson..Age?

[CarolinaDrumbum1]

I've got a 30hp Johnson for parts that is probably late 60's or 70's. i have looked for model numbers on the port side and cannot locate any id plate or model information. There is a number stamped on the block, 326713 and another number stamped on the bottom of the motor, 331474. does anyone have any idea what year it may be? thanks!

Look for a freeze plug/welch plug on the starboard side of engine block. That may have the model number on it.

If it's one of the old blue ones with a clamshell cover, then it's a 1956 model. Great motors! The 30hp was re-introduced in 1984, on
