I am sure Frank will mention the 25/20 jet option to you but just in case.............

The HP rating plate on your boat only accounts for the actual HP at the impeller which is 20 so you will be legal on PA waters with a 20hp restriction.

If you want to convert your existing outboard to a jet, there is 1 company in the US that has the patent on the jet pumps located in California. I think they call themselves Specialty Marine Company. Several years ago, the unit price was around 1500.00. If you are planning on doing a conversion, now is the time cuz they get backlogged with orders and sometimes require a 6 month waiting period during the summer months.

Here is the link to the company in Cali:

Good Luck!
