Dometic SeaStar Seal Kit, HS5157, with Wrench

The SeaStar Seal Kit is a must-have for anyone maintaining their hydraulic steering system. The kit includes everything you need for a smooth and hassle-free installation. The instructions are clear, making it easy even for those who aren’t seasoned DIYers. The seals themselves are high-quality and durable, ensuring a long-lasting fix. After using this kit, my steering feels as good as new! It’s a great value for the price and a reliable solution for keeping your system in top shape. Highly recommend!

Perhaps one of the easiest installations/fixes I've performed on any outboard. I have 26' Boston Whaler Outrage with twin 225 Merc Opti's steered with one HC 5345 Sea Star / Teleflex cylinder. One original seal began to leak slightly, so I decide to rebuild myself. The kit comes with all of the instructions, the magic wrench, and the upgraded seals (glands as they are called in the instructions), as well as the o-rings incase you need to disconnect the hoses and/or bleed valves. I did not have to remove the cylinder from the boat (yes, correct, I left the cylinder attached), nor did I have to disconnect the hydraulic lines. I was able to unbolt the bolts from the end of the piston and undo the bolts at the swivel and as if by magic was able to unscrew the leaking seals and slide off. Reverse for installation of the new seals. FYI - the new glands have more pin holes, so you are able to get the wrench on at more various angles versus the old glands which only had four pin holes. The teflon looking adapter slides over the threaded ends of the cylinder during install, and makes it super easy to install the new glands onto the piston with no damage. This might be hard to believe, but if you follow the instructions and turn the steering wheel (hence move the piston) the way it indicates, you will hardly loose any of that expensive Sea Star steering fluid. I replaced both glands and lost maybe 2-3 ounces total; not even enough to have to bleed or add fluid. I will top-off at the helm, but the loss of only a very small amount of steering fluid was remarkable to me.Bravo to Sea Star for offering us a rebuild kit which was easy to install and includes straight-forward directions. It sure beats paying a marina to do this same work at 5x the price! Thanks for a super product!

This kit has everything you need and saved lots of money on repairs. Watch YouTube for a 10 minute overview. The major issue is getting the brackets off. I used a drift pin, hammer and some penetrating oil. Don't bang to hard. Better many firm hits and more penetrating oil. Next challenge is to ensure the pins in the wrench seat well in old seals. The tool has a square whole to add a socket wrench for leverage. That work well for me. Seals fit well and went on smoothly. Good luck.

Seals are good. But the tool sucks. Bent on first try to break the cap loose. Invest in a better tool.

works good

Fantastic! I'm a DIY person with above average experience working on my own stuff. So when my P/Steering went out on my boat, I went looking. After watching numerous YouTube videos and deciding to do it myself I searched the internet and found Amazon had the best deal going. Could't have picked a better way to order the parts! The whole process was painless and my boat's P/Steering system is good to go!I highly recommend educating yourself b4 trying it. I watched numerous tips on that type of seal installation and purging the air (one person can do it by themselves). Get plenty of the recommended p/steering oil/fluid. I will say that I got the gallon size when I could have done it with 2 qts. But having it on hand and the price difference of letting my local dealership do it was a no brainer. Again the recommended fluid was ALLOT cheaper on-line. And delivery to my front door was a real time saver. I am a mechanic by trade so this was actually a very simple process for me.

Great seals and Completely worthless tool - Far worse than feared.Tool is aluminum and bends easily - pin holes bent and pins fell out - 3/8 torque hole rounded before reach torque. I used huge pipe pliers to remove end-caps, which were destroyed by the pliers. I did my best to install caps with the tool. If they come loose, I'll cough-up for a real tool. The wheel puller tool is a must, otherwise you will damage the easily dinged hydraulic bar; which means replacing the entire unit (SUPER EXPENSIVE). I used extreme caution and Spiral Wrap Tubing to protect the bar. Because I dinged my previous bar.

This is not from Dometic / Seastar / Teleflex. This is cheap knockoff that came incomplete (without plastic end cap or instructions). If you want the cheap knockoff, just buy the $25 part.
