Dometic SeaStar Seal Kit, HS5157, with Wrench

Worked well, no leaks.

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!

Seals worked on Sea Star cylinder

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.

I received the kit in short order. It was very easy to instal for one person. After installing the kit when you go to bleed the system it would be helpful to have a another person turn the wheel while you open and close the bleeders to remove all the air in the line. It took about 20 minutes from start to finish The instructions were very good. The one complaint I have is the price. Way out of line for what you get. What are you going to do when they are the only game in town. I would recommend this product only because it is the only one available. John Collins San Diego,Ca.

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.

Only replaced one leaky side. Easy to remove and install with supplied tool. No more leak and much cheaper to do myself.
