-------------I have an older Parker 1800 an I installed a MotorGuide iX5 24 volt, 80 ft/lbs thrust, 60'' shaft length. It's a 2019 model motor. I've had no issues with it.
The GPS antenna is also built in, so the only wires to run are your battery cables. Easy enough DIY job. I agree with Warthog5, I also ran 4 gauge cables (those cables are $$$) and a 60 amp breaker/cutoff switch. Both of my trolling motor batteries are in the console, so I snaked the cables through the tunnel to the transom box, then up to the bow under the gunwale cap and used about 30' of cable.
My iX5 has the "Pinpoint" GPS anchor, which is the feature I use the most. I fish the lower tidal Potomac, and it'll hold the boat in place with up to ~5 mph current and 15 knot winds. Any more current or wind than that and it's hard to fish anyway. It'll cavitate some in 2 foot seas, which again makes fishing a bit tough. A longer shaft wouldn't be a bad idea though, if I was buying another one I'd get the 72'' shaft just to have the extra length.
You can hear a slight whine when it kicks on, but its not loud. I also use it for fishing the skinny water, and it doesn't seem to spook fish. I've hit a few big rocks and logs with it in the skinny water, and it never damaged the shaft. My prop has a few small nicks, but I'm actually surprised at how little damage some of the collisions did to it and I'm still running the original prop with no noticeable loss in performance.
It's very easy to 'manually' drive the boat one handed with the remote while I have my rod in the other hand. When you're in a good spot, just hit the anchor button, and it holds you in place. You can also save up to 6 waypoints and have it run a course between them or take you to them and "Pinpoint" anchor.
The remote is easy to use, and the GPS connects quickly and holds signal well. I like to catch my bait fish under a metal bridge that's near my dock, and it even holds signal pretty well under the bridge.
This is my first GPS bow mount trolling motor, so I can't compare it to other brands. I'm happy with it, and would buy an iX5 again.
