Can someone ID a Johnson powerhead?

[Bearcamp]

There's a like freeze plug on the motor with the number 25352A and under that is E01615. Would that be the number to ID it or are there others? And if so, where? Need to know what year and hp.

Looks like the power head came off a 1973 25hp bearcamp.<br /><br />EDIT: First number (25352A) is the model #.
