Not an Aquasport story but it could apply to any motor.
The skeg on the C60 Yamaha on my flats boat was broken when I got it.
I procrastinated about getting it fixed until I got into some oysters and dinged the leading edge of the prop. Thank goodness I was only idling. I did not want to mess with welding so I researched the existing add-ons with nothing jumping out at me. I decided to go with the Blackfin just because it was easy.

Sand, clean, then tape off the gearcase.
The package
Tape off the skeg to keep the sealant squeeze out off.
Knowing how messy I am, I also taped some paper around the skeg. Here it's in a wooden jawed vise to hold it while you fill it with the adhesive.
It took the entire tube to fill the skeg to 1/2" from the top. Instructions said to use duct tape to hold it in place on the motor. I was not happy with that because it kept sliding a little no matter how tight I pulled the tape. I had some giant re-usable zip ties so I used them and a block of wood to hold in place for the cure.
One place in the instructions says 24 hour cure. Another says 72 hours so I left it the 72.
I fished the boat several days. I definitely have more steering torque. The boat seems to turn sharper but that is hard to judge because every time I used it the water was very choppy and I had total of 3 people in the boat and it doesn't perform so well when it's loaded that much.
I guess the next time I misjudge the depth of a flat we will see how rugged it is.
Oh, cost with shipping was something like $86.
