Awesome thanks for the info! I ended up getting a nice new 40# Minn Kota saltwater motor this afternoon. Also bought the Minn Kota power center battery holder and a 100 Ah Group 29 battery deep cycle marine lead acid battery. So I should be set for some long days out on the water sailing and trolling around!I do just use the standard motor vice screws to hold it onto the fiberglass and hadn't had any damage for a couple years.
I do just stuff the batter center up in the cuddy, but I have plenty of stuff up there... and oar, extra cushions for when we beach, boat bumpers that I use to roll up beaches etc. So I'm actually setting the center up out of any sloshing water (which is minimal) and it's braced by all the other stuff so it's not banging and flailing on it's own. Works great. I stuff the motor up there as well if you hadn't thought of that.. you will want it out of the way in good wind. I put it in prop first then there's a swing maneuver that gets the handle in. The battery center goes in last.
I can send pics sometime if you can visualize the functional mess up there.
Two questions for you:
-My transom is hollow and I have a hard time imagining that those clamps won't wreck it, even if I put some wood in between the planks to distribute the load. Do you know if your transom is hollow? Does it flex much? I can make it flex with just medium pressure from my hand.
-Have you capsized with your battery/motor up there? I'm pretty certain I'll be doing some capsizing over the summer and am afraid of the damage both to the cuddy and to the battery/motor...
