The hole in the rudders leading edge is there for the removal of the prop shaft without having to remove the rudder. If you can remove the prop with the rudder in place.

Update on this OP...
I finally got the modification on my rudder done. They attached a simple 6” strip of steel along the length of the trailing edge of the rudder (creating a 4” extension. Only $300 for the mod, plus labor for pulling/reinstalling.
The results are outstanding! My turning radius is tighter, my autohelm tracks better, and it requires fewer “points” to make a turn in an alley. Keep in mind, this is a single-prop with no thruster, often maneuvering vs current/windage. I highly recommend this mod!

Thanks for posting this up. We have the same type of boat, same engine, no thrusters, hell from your profile picture, we even live in the same marina. We'll look at having this done next haulout. If you could identify who did the work, that would be awesome.
Cheers!
Wayne& Dana.

Was it steel or S/S?

When you get on big following seas trying to not get broached way off course and at full throttle and full rudder deflection are you sure all the components are up to the resulting loads.

Regular steel, but then coated with layers of epoxy and then bottom paint.

That may not be the original rudder. There are plenty of "Ponderosas" around just take a look at one. It will give you a reason to walk marinas. Yours definitely looks on the small side.
My rudder is larger but when you are giving the throttle a "burst" to kick the aft around don't be shy. I give mine a kick up to a couple thousand rpm and maintain the burst for a couple seconds. The kicker boost is almost always followed by a similar hit in reverse.
Don't worry about gaining forward momentum. Your boat weighs 20,000 pounds or more, it aint gong anywhere from a two second burst.
But... I would add onto the rudder for the following sea issue.

This reminds me of the most outstanding shipyard repair work I have ever experienced - pasted from our website Alan & Joan's adventures sailing Moonstruck from America to the Mediterranean. Joan Teed's Art. - It concerns an over night rudder repair in Horta, in the Azores (in the Atlantic Ocean 800 miles off Portugal) during an Atlantic Crossing:
We made friends with John and Ashela on JSEA while we were in Ponta Delgada. John is from Vancouver and has sailed most of the voyage so far (from Antigua to Bermuda, and Bermuda to the Azores) with only half of his rudder! The remaining half was giving way as he arrived in Sao Miguel and was repaired last night. At 5:00 Friday evening, the yard started work. They hauled his boat out of the water, examined the damage, removed the remaining parts of fibreglass rudder blade from the Stainless Steel skeleton and welded on a temporary steel rudder made from two custom bent plates of steel. They applied two coats of epoxy, filled the fillets and at 9:30 pm left it to dry overnight, all while John attended the cocktail party in our honor. In the morning (This is Saturday morning) they added a coat of anti-foul and had him back in the water in time to leave with the rest of us at Noon. The Azores is an amazing place to have work done on your boat. I can not think of a yard anywhere that would have taken on work like that on a Friday evening and had it complete the next morning!

2 pieces of stainless about 10" X 21"
bent at 15 degrees
total cost about $80.00 Cdn (thats about $4.00US )
Two SS through bolts with spacers about $7.00
1/2hr. Installation
Massive difference in slow speed handing and even gained some steering in reverse.
