I have a 1987 23' CC with twin 110's with hydraulic steering. They work fine but the helm is hard to turn.

I have been using ATF instead of hydraulic steering fluid and have read that ATF will make for stiff steering. Fact? Also is there any kind of marine power steering?

The first thing to realize is that there is no such thing as a free lunch when it comes to steering your boat. Whatever energy that it takes to steer your boat is supplied by your muscles. Hydraulic steering is not power steering. However, there is such a thing as power steering available.

Having said that, yes oil does make a difference, especially in cold weather. However, I see you are in Miami so that's probably not a real big issue. I did see a boat once that was filled with Ford ATF, and what a stiff dog! Ford must have some kind of friction modifier in their oil ?

You can make it easier to steer, within limits, by selection of different helms. But the tradeoff is that to make it easier you have to make more turns hardover-to-hardover. Other factors are the motors, lubrication in the tilt tubes, if used, hose sizes, which ram you are using, etc. So you see, there is no pat easy answer to your question.

What brand steering do you have? I worked for Hynautic, and Teleflex was our arch rival. After I retired, Hynautic sold out to Teleflex. Hurts.

My steering is Hynautic and has been trouble free in the 13 years I have had this rig. Mine is a twin engine set-up with independant steering to each engine. This is a minor pain as I have to "center" the engines at least once a day but not a big deal. I do have a minor leak in that I have to add an ounce or so of fluid to the reservoir at the helm every trip. I bought the seal kit but decided not to bother until it gets worse.

I assume there is a reason you can't use a tie bar to connect the engines together and eliminate the synchronizaton valve?
