Nice rig.
I would change the prop (different pitch) to get to your preferred trolling speed.
I highly recommend only to use rec gas in it, with Amsoil.
Good Luck trolling, Maybe see ya on "the bay" someday I just bought a lightly used 2000 Alumacraft 18 footer (needed different prop), and I am smoking the 'eyes right now.
Sounds like sweet setup, Cooperfan. You're referring to Saginaw Bay, right?
