Suzuki Outboard Water Pump Repair Kits FAQ

How do I troubleshoot a Suzuki Outboard Motor?

It’s best to first address the simplest potential problems before getting into more complicated matters. The following quick fixes may address the reason your Suzuki outboard motor stopped working. 

• It may sound obvious, but check if there is gas in the tank. If so, is the tank vent open? A closed vent prevents air from replacing fuel as the motor pulls it out, which is necessary for firing up the engine. 
• If the kill switch isn’t properly attached it could very well be the source of your motor problems. Undo the electrical connection and put it right back into place. The kill switch may need to be replaced altogether. 
• The next point to check is your gear shift. It’s easy to knock out of place, which prevents the engine from starting. Make sure that you’re in neutral and try starting your engine once more. 
• Sometimes, the issue may simply be that your Suzuki engine propeller has something tangled around it. This may be a fishing line, excessive seaweed, or some other material that’s worked its way around the blades. Carefully remove anything that may be wrapped around the propeller, and give it a once-over for any damage that may be present. If the propeller is damaged, it needs to be replaced. Debris around the propeller is the most likely culprit if your boat motor starts, but quickly dies.
• Try to start the engine both with and without using the choke. If this doesn’t work, try altering the throttle position. Applying more or less gas can sometimes do the trick. Finally, squeeze the primer bulb a few times to make sure the engine is primed up.
• Some batteries have an on/off switch. If this is true for your battery, make sure the switch is on. Then, if your engine is under 25HP, you may be able to use the emergency cord to pull-start. It’s possible to do this with up to a 50HP engine, but be aware that the higher the HP, the more difficult this will be. If this works, the battery is likely the issue. You may need to replace it.

How do I service my Suzuki outboard lower unit? 

Suzuki lower unit gear lube is drained by removing the lower drain screw first and then the upper plug vent to allow air in. On most models, both plugs are clearly visible on the lower unit, but on models with low water pickups, the forward pickup will need to be removed to access the drain plug. 

Have a drain pan and extra rags handy as the gear lube will begin running down the skeg as soon as you remove the upper vent plug. Be sure to collect the fiber gaskets from both plugs after removal, as these are not reusable and should be discarded.

Use a properly sized screwdriver assisted by a wrench if necessary to loosen these screws which should be pretty tight. An impact driver and hammer may be needed depending on who serviced your engine last. The drain screw has a magnetic tip, so inspect the plug after removal to see if heavy deposits exist. Some fine shavings are normal, but chunks or a large quantity of metal are cause for further inspection. 

What are common Suzuki outboard engine fuel system issues?

One of the most common ways your Suzuki outboard motor will break down is a fuel system failure. Whether you’re experiencing an intermittent bog down, poor performance, or complete engine failure, your fuel system is a common culprit.

1. Ethanol gasoline: Only use premium low-ethanol gasoline for your Suzuki outboard motor. The reason is that ethanol attracts water, causing fuel to dilute through “phase separation.” Additionally, ethanol gasoline can also gunk up fuel lines and fuel system components due to additives used. To help prevent these issues, regularly use a high-quality fuel stabilizer and other Suzuki fuel additives (such as Suzuki ECSTAR Fuel Conditioner & Water Remover).
2. Fuel lines: Check your fuel lines. If you discover any breaks or leaks, you should stop using the engine and make any necessary replacements. Also, take a look at any fuel hoses with an interior liner.
3. Fuel filters: The Suzuki fuel filter is designed to catch any debris and contaminants that have entered your fuel system. Regularly replace your fuel filters to keep fuel running freely.
4. Fuel pump: A malfunctioning Suzuki fuel pump can significantly reduce engine performance and, over time, severely damage other components. If your fuel pump is not working correctly, replace it and any hoses that may have been affected.

Why is it important to flush my Suzuki outboard if I’m a freshwater boater?

Your Suzuki outboard is raw-water cooled, meaning it uses the water it’s operating on as cooling water. All water, fresh or salt, contains contaminants that will eventually build up in the cooling passages over time. Additionally, saltwater is naturally corrosive and any remaining in those cooling water passages after use is left there to do its worst, unabated. Saltwater can also experience crystallization when exposed to heat above 170 degrees, which causes deposits to form and potentially restrict cooling water passages. For these reasons, it’s a must that you flush your engine thoroughly with fresh, clean water after every use.

How do I perform a 100-hour service on my Suzuki outboard engine?

To ensure proper engine function, it’s always best to service your Suzuki outboard engine every 100 hours after the initial break-in period (first 10 hours) and after the first maintenance interval (at 20 hours). 

The following is a Suzuki outboard 100-hour service checklist to help you service your engine properly:

If you want a more in-depth explanation of how to perform a 100-hour service on a Suzuki outboard engine, read our blog “Suzuki Outboard 100-Hour Service Checklist”. Also, be sure to refer to your Suzuki Outboard Service Manual for which parts you’ll need, how to perform basic repairs, and other engine specific tasks

To make engine maintenance even easier, PartsVu has a wide selection of Suzuki outboard engine 100-hour service kits available. They’re pre-assembled with everything you need to keep your boat happy and healthy every 100 hours.

How do I know if I have water in my Suzuki outboard engine block?

If you are confronted with water in your Suzuki outboard engine, the first place to look before disassembling the engine and checking for a porous Suzuki outboard engine block, cracked Suzuki cylinder head, eroded exhaust-water passage, frozen oil cooler, or other labor-intensive issues, is the Suzuki thermostat. Remember that some engines have two thermostats, like Suzuki’s V-engines.

To locate the Suzuki thermostat(s), be sure to refer to the service manual as the location varies by the engine. The service manual procedure states that you should put the thermostat in a pot of hot water and check if it opens and closes at the correct temperature. If you do not have access to this method, then an infrared temperature gun can be used at the thermostat housing to get an indication of engine temperature. Again, refer to the service manual for the correct temperature operating range.

If you’ve determined that the engine is running cold, it’s a good indicator that the thermostat is stuck open. Remove the thermostat housing and inspect it. If it is stuck open, replace the thermostat with a new one, and be sure to do several oil and filter changes to ensure water is removed from the engine’s oil.

You might be wondering how water gets into the oil due to a thermostat being stuck open. If the engine is running cold, the hot oil meeting a cold engine can produce condensation. The condensation eventually condenses into water and falls into the oil. With an engine running cold, water isn’t the only pollutant getting into the oil. The piston rings (running cold) won’t fully expand to thoroughly seal against the Suzuki outboard cylinder wall and may allow a small percentage of raw fuel to constantly seep past them and collect in the sump. Prolonged running with this condition can cause the oil to develop a milky residue. Debris can also get stuck in thermostats and prevent them from retracting back to the closed position.

If you suspect water in the engine oil, there are a couple of quick ways to check. One way is to remove and look at the underside of the oil cap to see if there’s moisture in it. Another way is to pull out the dipstick to check for moisture in the oil. Either method is effective. Suzuki thermostat issues can be prevented by flushing the engine regularly per the owner’s manual.
