casement operator with exposed mounting

A quick learner from long beach ca says:

I am looking to replace my operator but I don't want to have to tear

out wood to do it. I have been replacing all my 9" operators with ones that have exposed mounting screws. but when it comes to the 13" ones all I can find are the kind that install under the sill.

can you advise?

If the sill covers the screws, you will have to pry up the trim in order to remove them. I'm afraid there's no other way around it. Check out the video below to see the best way to do so.
