Suzuki Outboard Propellers & Propeller Hardware FAQ

What causes outboard engine vibration?

One of the primary causes of Suzuki outboard engine vibration is a damaged or compromised propeller. A characteristic sign that your propeller is the source of your problem is if throttling to higher RPMs intensifies the vibration. 

First, check each of your props to ensure that each is in relatively good condition – any bends or damage can cause vibrations from the uneven propulsion. If you find damage, you’ll need to repair or replace it.

Suzuki propellers tangled with seaweed and fishing line can also restrict the propeller’s ability to rotate evenly, causing unwanted vibrations. If you boat in shallow waters or heavily trafficked waterways, you will need to monitor your propeller even more regularly.

During your inspections, be sure to look at your Suzuki propeller shaft for damage. Use a wrench to tighten the steering pivot and mounting bolt if either is loose, which may be the source of the excessive outboard vibrations. Once again, if you find damage or believe that the shaft is misaligned, you may need to visit your marine mechanic.

One of the most common types of Suzuki outboard engine vibration may come from loose engine mounts. As you throttle up, reverse, and idle, the bolts that mount your engine(s) may come loose during prolonged operation, creating an intermittent vibration – as well as steering issues (i.e., steering towards starboard or port when the wheel is straight). 

To rectify this vibration, mounting bolts should be torqued to the degree specified for your engine. Carefully use a torque wrench to perform this task accurately and to ensure equal torquing across all mounts.

How do I install a propeller on my Suzuki outboard engine?

While many believe that installing a new propeller on a Suzuki outboard is a tedious and cumbersome task, it is not the case. In fact, armed with the right knowledge, one can conveniently pull off the task of installing a new prop within a few minutes!

1. Using a screwdriver, push down the two bent-up tabs that are holding down the propeller nut.
2. Insert prop stop to prevent spinning.
3. Open lock nut retainer with Flat Screwdriver.
4. Remove prop nut.
5. Remove locknut retainer.
6. Remove drive sleeve adapter.
7. Remove drive sleeve from the boat propeller.
8. Remove forward thrust washer.
9. Clean any debris or old fishing line around the prop shaft.
10. Then inspect the shaft and analyze if it needs to be greased. If it does, coat a thin, even layer of grease on all of the splines.
11. Select replacement propeller
12. Install forward thrust washer
13. Slide drive sleeve into the propeller
14. Insert drive sleeve adapter
15. Slide the new propeller on the prop shaft
16. Slide locknut retainer on prop shaft
17. Insert prop stop to prevent spinning
18. Tighten propeller nut
19. Finish with torque wrench, and tighten the nut further until you hear a click sound.
20. Close locknut retainer against locknut

How often should you change your prop?

In general, it is recommended to change a boat prop if one or more of the blade edges are chipped or broken by over 15%. In case the propeller is in good condition, and the blades haven’t suffered any damage, you can continue using the same without the need to change 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. 

How do I choose the right propeller for my Suzuki outboard motor?

Your propeller decision-making process will include the following factors: pitch, diameter, aluminum or steel, blade number, rake, cupping, and rotation. 

Pitch is a critically important factor when selecting a new propeller. Pitch is the distance the prop would travel forward after one complete rotation, assuming no resistance or slip. 

If you need more speed, a higher pitch is generally the way to go. However, If you use a propeller with a too high pitch, the motor won’t have enough horsepower to turn it adequately, so the revolutions per minute will drop. Referred to as over-propping, it overloads the engine and causes excessive wear. Under-propping—fitting a propeller with too low a diameter or pitch—can damage your engine through over-revving. Under-propping will also adversely affect fuel consumption. 

A larger diameter propeller reduces the RPM and top-end speed. On the other hand, smaller diameter propellers increase RPM and top-end speed. However, smaller diameter props slip more frequently and are not good choices if hole-shot or acceleration improvement is your goal. 

Aluminum propellers are the most common and the least expensive. Stainless steel propellers are more durable and generally perform better due to both thinner and stiffer blades.

Most commonly, Suzuki marine propellers have either three or four blades. Three-blade propellers are most common on general use recreational boats. With only three blades in the water, they encounter less resistance increasing fuel efficiency, and they generally have minimal impact on your outboard engine’s RPM. 

Four-blade propellers improve hole-shot acceleration; therefore, commonly used on ski boats. These props improve handling and are generally better in rough water. 

Propeller rake is the angle that the blades slant backward. The higher the rake angle, the more the boat’s bow lifts out of the water. A high rake angle reduces time to plane and increases top-end speed. However, if a rake is too high, the outboard motor will operate under strain and experience premature wear.

A cupped propeller includes a curved lip to the trailing edge of propeller blades. It will get better traction in the water, reducing prop slip and ventilation, and improves hole-shot and acceleration. Cupped props allow the engine to be trimmed so the propeller is closer to the water’s surface and can dramatically reduce RPM.

Rotation is not an issue for most boaters as most outboards rotate the propeller shaft and propeller clockwise. However, a few run counter-clockwise, especially in dual outboard setups in which one motor runs clockwise, and the other runs counter-clockwise for better balance. Make sure your selected prop is designed for the correct rotation.

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.
