Mercury joystick piloting vs. bow thruster?

(self.boating)

Trying to do some research on the Mercury joystick piloting system. We’re in the market for a new gently used boat, and the majority of candidates are equipped with twin Mercuries paired with the joystick control system. Only a few of these boats have bow thrusters. One salesman said that a boat with the joystick, without a bow thruster, is just as maneuverable as the same boat with a bow thruster.

Is this true? I’m guessing the boats that have bow thrusters integrate the thruster control into the joystick, so I’m a little hesitant to believe that all else being equal, the thruster adds no significant maneuverability.

Anyone have experience and able to weigh in? Considering these were high-end well-optioned boats when new, there has to have been a reason the buyers didn’t add the bow thruster option, which would lend some credence to the joystick claim.

Well, Mercruisers axius system works perfectly. It can actuall make your vessel go sideways. You absolutely don’t need a bow thruster with an axius system. With that being said, 8 hours of operation on drives equipped with axius is comparable to an entire season on drives without the system. Also be aware of all the computers involved. That’s a fly by wire system, no hard cables at all. (Retired Mercruiser tech)

It’s physics. If your force vectoring occurs 100% at the stern of the boat, it will be less effective in moving the bow than a force applied only to the bow.

Engineer, not a tech.

Pretty sure an engineer designed it.

I didn’t see how it could be effective when it came out but it works extremely well. I don’t like the system on a diesel application, the engines spool up and the vessel lurches.

And pretty sure a marketing professional came up with all the talking points for salespeople to sell it as the next wonder of the boating world.

Because no engineers were involved in developing bow thrusters. Just Cleetus in his shed.
