I have a 2100 Tuffy Osprey with a 200 Verado Big Tiller Hydraulic Engine steering and while I was on Eagle lake Canada my Big tiller failed and I could not steer the boat, luckily I have a 15 H P kicker to get me back to the resort
In the Big Tiller Operation Manual Page 13 second paragraph it says
The power Steering System Has a Manual Steering Override
My Verado does not have it, Does any one knows about this Manual Override
Had to come home a week earlier, it pretty much ruined my trip

| Did you find out what caused it? I blew my battery isolator on Lac Suel this year, which meant the house battery (which powers the steering) wasn't getting charged and toward the end of the day I'd lose steering. It was still possible to steer, just a lot harder.
I've got a Verado as well, and it would be good to know about an override if the steering were ever to go out again.

Location: Glen Ellyn Il | Battery was not fully charged
The manual says that should be a manual override and actually all you need two fitting and a stop valve installed at each end of the hydraulic piston and open stop valve to equalize pressure on hydraulic cylinder
I actually rewired the two batteries so electrically I can run the steer from the starting battery and another switch to isolate the steer battery, very easy to do |

Yeah, if I'd known at the time the problem was the blown isolator preventing both starting and house battery from charging I just would have run everything direct to the starting battery and skipped the isolator...

Location: Glen Ellyn Il | talked to Mercury consumer affairs and they said there is no such thing as Manual Override, in other words the manual is wrong, I feel that Mercury is misleading the consumers and this is a problem that should be addressed by Mercury Big Tiller people
Not Happy
Here is their number
Mercury Consumer Affairs 920-929-5040
I will post the manual references |

Maybe it's meant to be a technician-only option in order to relieve the pressure when working on it, etc. with power disconnected? Ie., they don't want end users doing it?
There really should be a better way for the user to turn the motor without actually cranking it up...the old Merten's systems had steering power without needing the motor to be running.

Mercury bought Merten's, and then changed it to meet their business needs. You must have power to run the steering. There are a couple other options, but for a Mercury, this is the best one available to my knowledge, you just must be set up to power the beast ...

I am glad I have a 15HP kicker |

I also had a Merten's system in the past and now have a Merc Big Tiller, so, yeah.
Obviously power is needed for the pump to push the motor, one of the big differences is that the Merten's only needed the electric power turned on, whereas the Merc needs the motor to actually be running, which is a PIA when you want to turn the motor on your trailer. I'm confident there's some reason for it, but I'm not convinced that it couldn't be engineered differently...

| The 10:30 point of this video on the new Evirnude sytem is of particular interest.
