## Questions & Answers

**Q: Want to make sure it will work for hc5342**
A: This is the correct repair kit for your hc5342, please let us know if there is anything else we can do to helpThank you very much

**Q: do you have the seal kit HS 5156?**
A: Yes i do have them in stock.

**Q: I have a HH5271, will this kit fit ?  Thanks**
A: First, most suppliers on Amazon list the compatible model numbers for these seal kits.  Many of these kits fit multiple different model numbers so you can Google your model number to verify compatibility.
Second.  I cannot overemphasize the value of buying OEM replacement seals.  Definitely worth the cost difference in this case.  I bought cheaper knock offs to save money.  Argh.  Started to leak within a few months and could not get a response from the seller.  Amazon took care of me however.  Very impressed!  So I purchased OEM and they have been perfect.  But what a nightmare to have to replace them again.  The biggest hassle is the purging and addition of new hydraulic oil.  What a mess!  Obviously I don't have all the fancy equipment my mechanic has but it was eventually a happy ending and I still saved  bunch of money!  Have fun!

**Q: I have a 20' cc with one 1996 evinrude e200txedr with a seastar unit; i dont have the model number, as the cylinder label is gone.  will this fit?**
A: I’m not real sure, this kit fits the sea star pro unit! Mine is a 2006 with a 250 mercury motor!! They only have a few cylinders so I’m not sure what cylinder you have!! Sorry I couldn’t give you a solid answer!!

### ⭐⭐⭐⭐⭐ Perhaps the easiest repair I have ever performed!
*by R***T on October 7, 2015*

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!
