    I have a crazy question I just ran into winterizing my 2018 for the first time. Hoping that somebody else that has the SeaStar hydraulic steering can take a quick look at theirs and give me an assist, as I would sure hate to have to tow the boat back to the dealer to get an answer on this one.

    My steering cylinder has a grease nipple on the port side of the cylinder. However, on the starboard side, securing the ground strap, there is what sure looks like a grease nipple that my grease gun attaches to as expected. But there is no hole in the nipple. It's not clogged, I picked at it with an awl and it is filled with metal. I'm trying to figure out if I got a bad grease nipple that wasn't machined correctly, or if that fitting on the starboard side really isn't supposed to be a grease nipple.

    It's certainly easy enough to replace the nipple. but I don't want to shoot grease into some place that it was not intended.

    Can't help with your question as I don't have power steering but if it is plugged , the grease "ZERK" as they are called is a simple part to replace. If it's over/around any linkage I lcouldn't see how you'd hurt anything with grease.

    Are they for bleeding air out? I would hold off on pumping grease into the system for now.

    Top two look like hydraulic. Bottom look like grease zerks. And the bottom two look like pivot points.

    Thanks. The bottom 2 on Spoiledrotten's pictures are the ones. Talked to SeaStar - they are both grease zerks. They were great, immediately dropped me a new set in the mail. Upon examination of the new ones, they are unlike any grease zerks I have encountered in the past, the hole in the nipple has a small spring loaded ball bearing in it. I imagine to keep water out, and when you pump grease it pushes the ball in to open it up. Now I am thinking the old one maybe had a rusted ball or spring. Going to grease up the end of the zerks to protect that mechanism.

    All zerks have the ball and spring.
