Review of the HydraStar Marine Electric Over Hydraulic Actuator


Speaker 1: Today we'll be having a look at the Hydrastar Marine Electric Over Hydraulic Actuator, with breakaway and 7 way RV harness, rated at 1,600 psi. This is part number HS381-9067. Now the reason you're going to want an electric over hydraulic actuator to control your trailer brakes, such as this one is because it's far superior than your typical surge coupler style brakes that your boat trailers normally have. With your surge brakes, you have no control over it whatsoever. With this, you can dial up or down the intensity of the brakes being applied with the brake controller inside the truck.Also, when you go to back up your trailer with surge brakes, as soon as you start to back up, the brakes are being applied. The more force they're using to back up, the harder the brakes are going to be applied unless you have a manual lock out, which you have to get out of your truck, engage the lock out so you can back up without the brakes being applied.

With this, where you have your brake controller set up at when you're backing up, that's how much the brakes are going to be applied, so it makes it easier to back your boat into the water, down the ramp, but yet you still have some brake assistance there, so you don't have all the weight of the boat or the trailer, dragging you into the water.Also, with the surge coupler, the way the brakes are applied is the weight of the boat and the trailer start to push the coupler against your truck, and as the coupler collapses, it applies pressure to the fluid, and engages the brakes, so there is a delay of the brakes being applied. With the actuator here, being electric over hydraulic, is immediate. There is no delay, so as soon as we start to activate our brakes in our vehicle, the brakes are being applied on our trailer.Now this is a marine rated actuator. By being marine rated we have an aluminum construction here, which is corrosion resistant, and it is also vented to help relieve pressure and let moisture escape. This will ensure that our brakes will operate appropriately, and we don't get any moisture inside our unit causing corrosion and damage.

Our gaskets inside are also marine rated, so you don't have to worry about saltwater corroding them.Now what's great about this kit, compared to other options out there is that this comes with everything you need in order to convert your existing boat trailer or other trailer that has hydraulic surge brakes, over to one that has electric over hydraulic set up. We have our actuator, and a new junction box to hold all of our wiring, and a 7 way plug, so we can utilize the brake controller inside of our vehicle, which is great since most boat trailers only come with a 5 pole flat to get the reverse signal out to your lock out for your actuator. We also have this breakaway kit, with this nice battery box here, which is self-charging, so you don't have to worry about taking the battery out to charge it. It has a built-in charger, and we can check the condition of the battery by pushing this button on the top. We also have the breakaway switch, which will apply our trailer brakes in the unlikely event that our trailer came disconnected from our truck.

With the pin pulled, you can hear the brakes being applied.This kit is rated up to 1,600 psi, so it will be perfect for our disc brake applications on our trailers. It is rated to support trailers up to 3 axles, anywhere from 1 to 3. Now one thing that I really like about this kit, and with electric over hydraulic brakes in general, when comparing them to surge couplers, by having so much more control over them, we can activate our brakes manually from inside our vehicle by using the manual brake override on our brake controller, so if our trailer starts to sway side to side on us, and we need to bring in back in line of our vehicle, we can use the manual override by sliding the adjuster over, just to slow our trailer down and bring it back in line. With the surge coupler, you can't do that. Many of our customers feel that this is a much safer way of towing their trailer behind their vehicle.When comparing this actuator to other electric over hydraulic actuators out there, such as the Dexter DX Series, this is a much slimmer design actuator, so we're much more versatile in our mounting solutions.

It will work great on top of narrow channel frame trailers, such as this one.Now for a few measurements to better assist you in choosing mounting locations for your components, our actuator measures 11 3/4 inches long. It is 3 inches wide at its widest point, and it is 7 3/8 inch tall from the bottom to the top of the cap. Our junction box, at its longest points, measures 6 3/4 of an inch long. At its widest point it is 3 1/2 inches wide, and it is 2 1/4 inch tall. Now the battery box for our breakaway system is 5 7/16 of an inch long. It is 4 1/4 inch wide. It is also 4 1/4 inch tall. Our 7 way cable measures 6 feet long from the very end, to where it goes into our junction box.That completes our look at the HydraStar Marine Electric Over Hydraulic Actuator with breakaway and 7 way RV harness, rated at 1.600 psi. This is part number HS381-9067.
