Outboard Steering Cylinder Maintenance

Outboard Steering Cylinder Maintenance – Video Transcript

Hi there my name is Mark Adams with SeaStar Solutions. Welcome to our technical training videos. Today we're going to discuss the regular maintenance of a SeaStar outboard steering cylinder.

Proper and regular maintenance of your SeaStar outboard steering system is going to prolong seal life as well as ensure system performance. It's going to make you and or your customers very happy. Today we're gonna remove the support brackets and the support rod. We're going clean, re-grease everything and then reassemble everything back together. We recommend that this is done at least once a year for fresh water and at least twice a year for saltwater.

Only a few tools are required to maintain your SeaStar outboard steering system. You're going to want to have your installation manual, a 5/8" a 3/4" wrench and socket you're going want to have a 5/32 allen key so you can loosen and remove the adjusting nut. you're going want to make sure you have a torque wrench so that you can properly torque everything once you go back to do the installation. And you're going to want to have a rubber mallet just in case things get stuck in the engine tilt tube.

The first thing you want to make sure is that everything is clean and ready for removal. Some good heavy-duty penetrating spray will assist with the removal of the fasteners themselves. We're going start by removing the larger of the two nuts This is the 3/4 inch socket for the support bracket. Just using a socket you're going remove this bracket and then sure you catch all of your hardware as it falls off the end of the shaft. Next we're going remove the shaft nut which is a 5/8 and again make sure you keep this. Next we're going remove the support bracket, if regular maintenance was completed this should be easily removed if it's difficult to get off just a couple light taps with a rubber mallet ensuring you do not damage the cylinder shaft itself should release the bracket from the system.

After this we're going to remove the support rod key, your washers and spacers taking note on what position they're in. Set them aside for later use. Once you remove your support bracket, your washers, your spacers and your adjusting nut you're going to repeat the exact same process on the other side. Next we're going to remove the support rod. Again this should be easily done if the systems been regularly maintained. However if it is stuck or seized inside there a couple good shots with the rubber mallet will get it loose. Once everything's been removed you want to clean everything prior to reassembly.

Using a flashlight inspect the engine tilt tube for any kind of corrosion. If corrosion is present use a wire brush to get it good and clean. A clean tilt tube is extremely important for the performance in the maintenance of the system. Before putting everything back together this is a great time to make sure that this engine is moving freely. If this engine cannot rotate left and right easily you're going to feel heavy steering at the wheel. As you can see this engine moves back and forth easy. If it does not you want to ensure that this gets dealt with before putting anything back together. Now it's time for reassembly. First thing we're going do is make sure that the support rod itself is good and clean. Once we've cleaned the support rod we're going to take a good quality marine grease and liberally coat the entire length of the shaft itself. Once that's done we're going slide it into the engine tilt tube. Next we're going to put the adjusting nut, washer and the spacer back on.

I took note of the orientation prior to removal so I'm going put them on the exact same way that they came off. You're going to want to thread the adjusting nut all the way on to the engine steering tube make sure your washer goes on next then your spacer and finally in this case your key. Now we're going to install the support bracket as with the support rod you're going to use a good quality marine grease and you're going to grease the two inside portions of the bracket itself prior to installation. Next we're going to put our washers and nuts on the support rod as well as the cylinder shaft itself.

Once you've installed your washers and your mounting hardware we're going to tighten and torque the cylinder shaft as well as the support rod shaft nuts. Make sure you torque everything down before you adjust the adjusting nut itself. Once this side is tightened and torqued properly you want to repeat on the opposite side of the engine. The final step of the installation of the cylinder on the outboard is removing all slack from your spacers. That's done with the adjusting nut, you just rotate this adjusting nut until it makes contact and then tighten hand tight. Once it's tightened in place using your 5/32 key, lock the nut down. And that concludes the maintenance of the outboard cylinder. If you have any questions about this process just feel free to give us a call at SeaStar technical support we'll help you out.
