External Steering......Need Feed Back
Hey give me thoghts on External steering. I have just refresh motor in donzi 22zx. should be 550-600 hp. I know i need external steering but my thoughts/money are go with dual ram add-on or full hyd single ram.
We mainly run lakes in Texas nothing crazy majority of time but look for thoughts on safety. Gimbal etc in great shape, but I have been reading add-on stiffens steering and wife drives boat also so will it make to stiff.
I am torn between dual addon then doing full next winter or just doing single ram full.. Give thoughts boat should run top end about 80-85

I also wouls like to know the same thing. Im in the same boat about this stuff. If the dual ram add on would be plenty or not. Im running about the same speeds and the add on dual ram would be alot cheaper but just dont really know how much the dual ram add on would help. Thanks for any info.

Send hallj on here a message. he is my brother and very knowledgeable on this subject. He has done it on a few boats including his Donzi Minx and a Chris Chraft XK-19. We are doing it on my Formula 242 this spring.

If your budget allows, dual ram full hydraulic with externally mounted cylinders is best. A single cylinder setup will be just fine as well.
Do you plan on using the assist of your PS pump?
I wouldn't bother with systems that mount the cylinder inside the transom as they don't reduce load on the gimble and you are still steering through all of the slop in the Mercruiser steering arm and gimble assembly.
let me know if you have more questions.

Had Lathem dual ram add-on on previous boat. Drive was rock solid with no play. It was a little stiffer at idle speed, but nothing more than a standard PS setup. Off idle rpms it was fine. Current boat is full hid dual. 1 touch finger control at all rpms.
If cost is a concern, get the dual ram add-on, then convert to full when possible.
My thoughts on single ram.....
In theory, the single ram should have an uneven ratio between left & right turns do to the difference of sq. in. on the ram piston. (difference being the rod) In real lifel use, I don't know. Leave that to a user of one.

if you are going to run over 80, you need a dual full system, the dual one takes a ton of load off the housing..real bad things happen when they break...just did mine...CP performance has decent prices and parts..
