    All of the above, maybe add a bigger tank too if it’s undersized.

    Make sure the steering wheel can move in and out in the mount , not bound up, make sure to keep it greased, this can cause problems. They tend to run hot, and if you have one tank for a hauler and steering, adding a cooler will help both. I had a boat that had separate tanks, and the helm was hot to the touch, and the oil would turn black. Never had any other issues with it, and I had the boat for 13,000 hours. Is the pump pully driven? Sometimes a smaller pulley to slow down the oil . If you have a lot of 90's in the system, they cause heat.

    Thanks for all of the help there is a separate Pump and tank for the steering the pump for the steering runs off of the reverse gear when I first start running the boat it’s nice and easy then starts to stiffen up the longer I run it
    The wheel doesn’t seem to move in and out of the mount much

    We use synthetic ATF here and should be 6-8 inches down from the top of the tank.

    Couple of things to check. First make sure that when you turn the wheel and then take your hands off it that it makes just a little wiggle. if that shaft in the helm is binding up at all it means that helm is still trying to be on so to speak. Makes a ton of heat that way. Also look at the filter where return fluid goes back to tank and make sure the arrow on top is pointing the right way. That really heats them up too. If the pump is anything bigger than a v-10 its more than it needs. It should have a cooler too- we put one in every system. They are a great system when things are right with them, you should be able to leave your hand on the helm and have it just a little warm.

    If you have the wrong fluid in the system it may also get hot and not perform well.
    My Duffy also has belt driven system like a hydroslave but made by Downeast Marine Engineering, but they no longer market this system. They should because they are excellent helm units. It uses hydro fluid like you put in hydraulic driven construction equipment, very slippery stuff, and a 10+ gallon tank that I keep about 2/3 full. The helm units will be warm to the touch after running but not hot and it never gets harder to operate.

    Power steering is new to me. I'm learning. Thanks for all the good info !
