Kicker motor installation

[IA bowhunter]

I have a 24 ft Penn Yann, with the long transom I had to get the long kicker bracket due to the height of the transom and the marina has asked several times if this is what I really want as it is a little pricey mounting it to include the mount and the stering bar and fuel line hook up. Not knocking the marina at all just a little skeptical as if its going to be worth it. 4 stroke 9.9 kicker motor cost 875.00 ( I bought seperate)and installation to include controls with steering bar and hooked into my fuel lines 10 hrs X 68 dollars an hour. I know in the long run it will,just want some reassurance and my boat back. Anyone else that has a long transom and what issues /problems did you go through mounting the kicker motor
