1992 mx19
 

I believe that my boat uses a 14.5 19 pitch prop. I have an opportunity to use a 14.25 mercury SS 22 pitch prop. Any problems?

Read the Sticky entitled Basic Propeller Rules. That 3" increase in pitch will result in a WOT drop of about 600 rpms which is a lot. For every inch increase results in a 200 rpm drop and every inch decrease results in a 200 rpm increase (give or take a few).
