Anyone know anything about Mariner Trolling motors

(I have this in my build thread but thought id get more traffic if I asked here)

I just got a foot controlled trolling motor from my dad for free.  Its an odler style but Ill tell you what, it looks like a stout beast.  all metal design so I dont have to worry about breaking anything lol. 

Its a Mariner 422R (I think) trolling motor and the only thing I know about it is what I found on iboats.  does ANYONE know anything about these or owned one?

Here is what i found (not my motor, but i have one exactly like it)

Well, after playing with it a bit last night, I think I have it figured out. It's a scissor mount, but it isn't nearly as easy as pulling a cord and dropping it into position.

Stowed position:

Operational postion:

Switching between the two, while on the water, may be interesting to put it mildly.

Step 1: Climb out on bow

Step 2: Release catch (marked by yellow arrow)

Step 3: release second catch  (marked by yellow arrow)

Step 4: rotate various pieces into operational positions

I can definitely see myself going overboard trying to stow/un-stow this beast.

Also, should I just screw it down with BIG stainless screws like I used on my casting deck and stuff?
