Look under the prop nut for numbers.
What year Johnson?How many cylinders?
Read the stickys at the top of the prop forum.
Get us as much info as possible.
If it won't plane a 15ft boat with one or 2 people in it I thank you have a setup or motor issue.
Be sure its running on all cylinders. Be sure the throttle opens all the way.
