I have seen that tutorial before on refitting the transom on that Grady. That guy is a genius with fiberglass. He is also, obviously directly related to the Energizer Bunny, because he relentlessly pursues his objective. Quite the project.
The "bow catcher he designed and built on the trailer is quite special. That whole sequence is a 2 to 3 beer read. My hat is off to Mommas' Worry.
Working on a re-power at the end of season (2023) ..... only options are ......... Etec 200 (I bought a good pair 2014 200's , 700 & 800 hrs,can be for sale ) removed from a fresh water Grady ..I wanted 300's instead (cannot find any).. same weight ..
or Suzuki DF200AP (4cyl) ($42K,aprox) or DF250AP (V-6) ($52K ,aprox)............ this can be a no-brainer lol
