It is easy to make mistakes so you must do your arithmetic before you buy the parts. In the end, the cost difference is minimal. your assumption of similar maintenance between hydraulic and cable is flat wrong. There is much less maintenance on hydraulic systems. In fact, if designed and installed correctly there is No maintenance, just occasional inspection. Steve "Bob La Londe" wrote in ... As I'm sure you are aware in a lot of bigger outboard applications it can be really hard to turn the wheel under high throttle due to side torque. Its why a lot of (most?) bigger bass boats have hydraulic steering. Any reason you can see not to go with dual cable push pull steering on with a jet lower unit? Obviously push pull cables require maintenance, but so do hydraulic systems. I'm probably going to wrap up the weld & rebuild on The Tin Can Too in the next couple months and I have a bigger project in mind. I already have a decent push pull system laying around from another boat I cut up and threw in the dumpster a piece at a time. Is it recommended to use a cable or hydraulic system with outboard units. I am building aboat that is supposed to have twin 40's and I will need a steering system. which is better and easier to install with least amount of follow-on maintenance. Hydraulics ARE easier to steer with and require less force to use. Hydraulics sized properly for your application will last a long time with minimal maintenance. Repairs will cost more when it is needed however. If you are using counter rotating engines side torque will be less of an issue and with the small motors you are using it won't as bad as if you were running bigger motors anyway. I would still go with a hydraulic steering system if I had no steering system already. Tons of bassers had no issue steering 150 HP motors with cable steering. As the motors get bigger, speed gets higher, and the RPMs climb it becomes harder and harder to turn under power with cable steering. I can't imagine driving one of Allisons world record setters without hydraulics, but I have two boats with 50 HP motors and top speeds of 32 mph and 44 mph respectively that handle just fine with cable steering. With two motors as far as I know they only issue is how you choose to link your motors together. My dad's inshore / light offshore rig has dual motors. I can look at it if you like, but I don't think it is that big of a deal. He is running hydraulic steering, but he as dual 150s back there. I would like to point out that when I say cable steering I DO NOT MEAN a cable drum with ropes and pullys. I mean linear jacketed push pull cables made to handle the application. Thanks for the input. Yes this is a fresh installation. Do not currently have a steering system and I am trying to find out which method is better. The cable systems that I am looking at are of the type you described, that being a jacketed cable system. I haven't seen anything in supply store web sites about hydraulic, so the first time heard of them was right here. any other ideas, thoughts or inputs are greatly appreciated. currently the boat is upside-down and slowly getting the battens, sheers, and chine placed so I can shape the stem/keel and get ready to cover it. I have already purchased the plywood (marine grade fir) to cover it, and will be glassing that after finishing up. I'm no expert on hydraulics, although I have had a couple boats with hydraulic steering. If you decide to go that way or atleast investigate it more thoroughly I suggest you start by beginning a new thread here. (since I already torqued Steve L and Wally (pun intended) in this thread.) I do not doubt Steve is well versed in hydraulic steering and could guide you towards the best compromise between price and durability for your application. I suspect that a dual cable steering would probably be overkill for you, but I have not run single cable on anything over 60HP personally. I also think the side torque of two 40s will be greater than that of a single 80 unless they are counter rotating (which I think is unlikely in that size). For that low of an HP rating almost any decent hydraulic will probably allow you to steer with one hand. Teleflex is one company who makes hydraulic steering systems. There may be others, but it's the one I am familiar with. |
