Check for adequate grease on the motor

If your boat's steering is unusually stiff, it is important to check for adequate grease on the motor. Grease is necessary to keep the components moving and functioning as they should. Without this lubrication, the steering wheel may be difficult to turn.

To do this, first locate the motor. Look under the power head of your motor where the motor pivots on the shaft. Here, you should find several grease nipples. These need to be greased at least annually and should be well-greased to promote smooth, unrestricted movement. A good rule of thumb is to grease this area about once every 12 months.

If it has been over a year since you last greased this area, or if there is little-to-no visible grease remaining, you should add more. Be careful not to add too much, as this can blow out the seals, depending on the type of grease and the mechanism. If you are unsure, consult your boat's manual for guidance on the type and amount of grease to use.

In some cases, you may find that the grease is not reaching the top of the pivot shaft. This can happen if there is only one grease nipple at the bottom of the shaft, and the grease is not flowing uphill. To resolve this, you can try gently heating the shaft with a portable butane torch until the outboard can be turned freely from side to side. You can then pump fresh grease into the bottom grease nipple. If this does not work, you may need to carefully drill a hole at the top of the shaft and screw in a grease nipple to get grease to where it needs to be. Remember to remove the grease nipple before operating the boat, as it may prevent the outboard from turning fully due to lack of clearance.

Additionally, it is important to check for grease in other components of your steering system, such as the steering cable and the tilt tube. The steering cable, which connects the steering wheel to the motor, should be inspected and greased at least annually to prevent issues. The tilt tube should be cleaned and lubricated with white marine grease once a year for fresh water and twice a year if you are boating in saltwater.

Inspect steering cable for corrosion

If you're experiencing stiff steering on your boat, it's important to inspect the steering cable for any signs of corrosion. This is a common issue, especially in saltwater boats, as salt speeds up the corrosion process and leaves behind abrasive grains of salt. Here are some detailed steps to help you inspect and address any corrosion on your steering cable:

  • Initial Inspection: Begin by visually inspecting the steering cable for any signs of rust or corrosion. Look for discolouration, flaky substances, or any other abnormalities along the length of the cable. Pay close attention to areas where the cable enters or exits components, as these are prone to corrosion.
  • Disassembly: If you suspect corrosion, carefully disassemble the steering system to gain better access to the cable. This may involve removing the steering wheel, disconnecting the cable from the motor, and exposing the entire length of the cable. Be sure to consult your boat's manual or seek guidance from a marine mechanic if you're unsure about the disassembly process.
  • Cleaning and Assessment: Once the cable is accessible, use a clean cloth or sponge to wipe down the cable. You can also use a mild solvent or marine-safe degreaser to help remove any grease, grime, or salt buildup. After cleaning, carefully inspect the cable for any signs of damage, pitting, or extensive corrosion. Look for areas where the cable may have weakened or become restricted in movement due to corrosion.
  • Minor Corrosion: If you notice minor corrosion or surface rust, you may be able to remove it by scrubbing the affected areas with a wire brush or fine-grit sandpaper. Be gentle to avoid damaging the cable. Once the corrosion is removed, apply a corrosion inhibitor or protective lubricant to help prevent future corrosion.
  • Severe Corrosion: If the corrosion has eaten through the cable or caused extensive damage, replacement is usually the best option. Consult a marine mechanic or a boat repair specialist to obtain a replacement cable that matches your boat's specifications. They can also guide you through the replacement process to ensure proper installation and functionality.
  • Prevention: To prevent future corrosion, it's important to regularly inspect and maintain your steering cable. Clean and lubricate the cable according to the manufacturer's recommendations. For saltwater boats, increased maintenance may be necessary to combat the accelerated corrosion caused by salt exposure.

Remember, safety should always be a priority when working on your boat. If you're unsure about any aspect of the inspection, repair, or maintenance process, don't hesitate to seek professional assistance from a qualified marine technician.

Grease entering support tubes

Grease entering the support tubes is a common issue with outboard engines. The support tubes have grease fittings, and if these are not greased annually, water can enter the tube. This can cause the link arm to seize, resulting in a binding in the steering linkage and a hard-to-turn steering wheel.

To fix this issue, you will need to remove the smaller hex nuts holding the steering links at both ends of the hydraulic ram. Then, you can pull the links out of the steering tube. Next, thoroughly clean the inside of the steering tube and the links. You can use a wooden dowel with a solvent-soaked rag wrapped around it to clean the tube. Work the solvent-soaked rag in and out of the tube until all the old grease residue is removed.

Once the tube and links are clean, you can pack some fresh grease into the tube and coat the links with fresh grease. Reinstall the links, using new nylock nuts to secure them to the ends of the hydraulic ram arms. Finally, pump as much grease as possible into the steering tube via the grease fittings on the outboard engine steering tube and bracket. This should allow the link arm to articulate freely, and your steering wheel should move without difficulty.

It is important to note that if the grease fittings are not adequately greased, it can lead to the issue of grease entering the support tubes. Therefore, it is essential to ensure that the grease fittings are properly greased at least once a year to prevent this problem.

Check for tilt tube problems

If you've checked for problems with the engine, stern drive unit, or rudder and the steering problem persists, it's time to inspect the tilt tube. The tilt tube is a metal tube through which the inner metal cable sleeve is routed. It fixes the cable's end in place and allows for adjustments to fine-tune the steering system.

Your tilt tube should be cleaned and lubricated with white marine grease once a year for fresh water and twice a year in saltwater. If the boat has been sitting and the grease has been allowed to harden or corrosion to build up, the cable end will not move freely through the tube. This can be a challenge to disassemble and repair. You may need special equipment like a torch or a push rod to get the cable end out of the tilt tube.

Start by unscrewing the nut that connects the outer sleeve to the tilt tube and carefully removing the cable end in its metal sleeve (if possible). If the cable end is stuck in the tilt tube, it's time to call a professional. If the cable end comes out of the tilt tube and this fixes the problem, clean the tilt tube, lubricate the cable end with marine grease, and reassemble the steering.

If the problem persists, move on to the helm. Disconnect the rack or remove the cable end from the rotary gear. If the steering was stiff or sluggish before, but now the wheel moves freely, you need to take a closer look at your cable. Trace the length of the cable to ensure it is not bound anywhere. The maximum bend allowed for most cables is an eight-inch radius. If you find an area with too sharp of a bend, readjust the cable accordingly.

Check for leaks in hydraulic steering

If your boat has hydraulic steering, leaks are a common cause of stiff steering. To check for leaks, you must first identify where the hydraulic fluid is located on your boat. This could be in the deck, the helm, the lazaret (if your boat has one), or the transom or engine compartment. Once you have located the hydraulic fluid, inspect these areas for any signs of leakage. Common leaks occur where the hoses attach to various components, such as the helm and the steering cylinder. If your boat is a larger vessel, it may also have multiple steering cylinders, reservoir tanks, autopilot pumps, additional helms, or other installed hydraulic equipment, which could be potential sources of leaks.

It is important to routinely inspect the cylinder rod for any nicks or dings, as these can damage the seals and cause leaks. If you do detect a leak, you can then troubleshoot to identify the cause and fix the problem. If the leak is due to a damaged seal, you may be able to repair it by sanding down the affected area with extra fine (400 grit) sandpaper.

Leaks can lead to low fluid levels, which can cause steering issues. Therefore, it is important to check your hydraulic fluid level before heading out on the water. This is normally done at the helm, which should have a removable bolt or screw at the top for fluid checks and refills. When adding fluid, always do so in stages, turning the wheel from lock to lock several times in between to help bleed air and distribute the fluid evenly throughout the system. Larger vessels may have a separate reservoir for hydraulic fluid, which is where you will check and add fluid if needed.

Frequently asked questions

There could be several reasons for stiff boat steering. Some of the most common ones are:

- Lack of lubrication: Grease is necessary to keep the components moving and functioning as intended.

- Corrosion around the steering cable: Rust and corrosion can restrict the normal movement of the cable.

- Grease entering the support tubes: Grease from the fittings can get sucked into the support tubes, resulting in a hydraulic lock.

- Tilt tube problems: The tilt tube should be cleaned and lubricated regularly to prevent the build-up of grease and corrosion.

- Steering cable issues: The steering cable may need to be adjusted, cleaned, or replaced if it is not functioning properly.

It is recommended to grease the steering components at least annually to ensure smooth and unrestricted movement.

It is important to use a high-quality marine grease that is suitable for your specific application. Using the wrong type or mix of grease can lead to issues.

If you notice that your steering is stiff or sluggish, it could be a sign of a problem with the cable. Inspect the cable for any binding or sharp bends that could be impeding its movement.

To troubleshoot stiff steering on an outboard boat, you can follow these steps:

- Inspect the steering wheel, steering cable, outboard pivot point, and tilt tube for any signs of damage or corrosion.

- Clean and degrease the steering components if necessary.

- Check the fluid levels and add fluid if needed.

- Bleed air from the hydraulic system if there is a "squishy" or unresponsive feeling in the steering.

- Seek professional assistance if the problem persists or if you are unsure about any of the steps.
