Hey NL,
I will cast another vote for the TR-1. If it's an independent system you're looking for then this is it!
Yes, it's expensive but with the strong Canadian dollar you can probably score a deal at portlandmarineelectronics.com
Ask for Todd and tell him Nelly sent you!
If you've spent any time at all wrenching on your boat then the TR-1 system is no real biggie to install.
There are five components:
-Electric/Hydraulic pump
-Steering ram that mounts to your kicker above the lower unit
-Remote throttle mounts to the kicker's carburator
-Compass ball which mounts forward of your boat's pivot point
-Hand held remote and deckmount (on/off) switch
Optionally, there is a wireless control fob that looks like a keyless remote entry pad for a car. The wireless hangs around your neck and allows you throttle and steering control from anywhere in your boat!
The Electric/Hydraulic pump needs to live in a splash-proof location and the Compass ball will have no problems staying happy up forward in your 21', tucked up under the gunnel.
Depending on your use, you should enjoy 3-4 years of trouble-free use and then there will be some maintenance but overall, it's worth it.
The TR-1 is basically a silent, invisible fishing buddy that steers an inhumanly straight course, takes up no room, drinks no beer and doesn't fart or smoke.
It's fish netting skills are non-existent however...
