Which Propeller Is Best For My Boat

Aluminum Or Stainless Steel Prop

The Correct Prop For Your Boat! How To Know!

Another choice to make is choosing between aluminum and stainless-steel materials. Common with new package boats are aluminum props, which are inexpensive and repairable. Consider these differences when thinking of upgrading to stainless steel. Thinner blades and more advanced designs give stainless steel a performance edge over aluminum. Stainless costs more but is five times more durable than aluminum. Stainless props can be repaired, at a higher cost, to like-new condition, while repaired aluminum will suffer from metal fatigue and a loss of strength.

Family & Watersport Boats

Reliance

The Reliance family of outboard props is also great for many family boats pulling towables and boaters who participate in watersports.

Talon Pontoon

Excellent low-speed operation, providing higher thrust and control than conventional propellers on pontoons using T50-F115 outboards. Features an SDS design that requires no special hardware to function.

Dual Thrust

Harnesses the power of Yamahas high-thrust outboards for pushing heavy loads such as sailboats and pontoons, and provides outstanding reverse thrust. Standard on T9.9 and T25, optional on T50 and T60.

Pros & Cons Of A 4 Or 3 Blade Prop

For us, if we go from a three blade to a four-blade without changing the diameter or pitch of the prop, we will lose top-end speed. What we will gain, however, is our hole shot .

Meaning we will be out of the water and cruising much quicker thanks to the extra blade generating a better grip from the prop to the water.

With the extra grip also comes better control and handling of our craft. Understanding these simple concepts is the crucial base foundation for us to begin the propping procedure to get the correct prop for your boat.

At the end of the day, it is ultimately up to you and what you are looking to get from your boat. Would you rather have a better hole shot or top-end speed?

Its your call! Personally, running larger boats close to the 30-foot range or higher calls for a 4 blade as its best for the size and weight of the boat. That extra blade really makes a notable difference in getting the boat out of the water and controlling it at higher speeds!

    Does My Boat Have The Wrong Size Prop

    If the boat is over-propped the engine will not reach maximum rpm and the boat will underperform. Equally, if a boat is under-propped and the engine easily reaches or exceeds maximum rpm, the propeller needs more bite to get the boat to maximum performance level.

    With outdrives, adjusting the pitch of the prop is often the only option, as the maximum diameter propeller is often already installed. Increasing the pitch will decrease the revs and vice-versa. If the engine revs seem OK with the current prop, but you want better acceleration, it is often possible to reduce the diameter and increase the pitch by roughly the same amount to give added acceleration without losing the top-end speed.

    Tips On Choosing The Right Propeller For Your Boat

    Does your boat take a long time to get up on plane? Maybe not hitting the top speed you think you should? Are you looking for better all-around performance and fuel economy? Apart from keeping your boats hull clean and your engine tuned, selecting the right propeller is one of the easiest actions you can take to get the most out of your boat.

    First of all, note that the primary criterion for selecting a propeller is to make sure it allows the engine to turn up to a speed within the range specified by the engine manufacturer usually within 500 revolutions of absolute top rpm. This ensures a long life for the engine, neither lugging it down nor letting it over-rev. Your engine probably came with a propeller that achieved that basic requirement, but you can select a variety of props that will allow the engine to turn up yet have differences in pitch and number of blades, plus possess more subtle characteristics. For example:

    Propeller Size

    Expressed with two numbers, diameter and pitch, with diameter always stated first. Diameter is two times the distance from the center of the hub to the tip of any blade. Smaller prop diameters generally go with smaller engines, or with fast high performing boats. Pitch is the theoretical forward distance, in inches, that a propeller travels during one revolution. Think of pitch as speed, or as the gear selection on a cars transmission.

    Three or Four Blades

    The Meaning Of The Numbers On A Prop

    Choose the right propeller for your boat

    Typically, most propellers will have specific information engraved on them. This information usually consists of two to four sets of numbers and letters.

    One being the propeller diameter, the second being the pitch length, third representing the rotational direction and fourth being the bore/shaft diameter.

    An example of these numbers displayed resembles the following: 15.6 x 15 | RH | 1 ¼

    The Quicksilver Black Diamond is the best all around boat prop youre going to find. Its not too expensive, but its built to last and to perform. In fact, its the best-selling aluminum prop in the world.

    This is Quicksilvers 3 blade design. Its right hand and comes in a large range of pitch sizes. You can use this anywhere from 25 horsepower up to 250 horsepower outboard motors. Its also suitable for Alpha One sterndrives. It operates with the Flo-Torq hub system youll find on many outboards.

    The included hub will work for engines up to 60 horsepower. If you have a bigger engine, you can pick up a different hub system to get the job done.

    Once installed, expect to see a big improvement in planing. This model also offers a solid hole shot. That refers to your boats ability to accelerate. That means from a standstill or just low speed. If you hate slow acceleration, a good hole shot is important.

    Should You Pitch Up Or Pitch Down

    Boat Propeller

    Engine rpms and pitch are inversely related. Increasing the pitch will decrease engine rpms and decreasing the pitch will increase engine rpms. As a general rule, a two-inch increase in pitch will result in a reduction of 300 to 400 rpm. Conversely, a two-inch decrease in pitch will result in an increase of 300 to 400 rpm. Going back to the question of performance at WOT, if your engine is under revving, consider a propeller with less pitch. If your engine is over revving, consider a propeller with more pitch.

    What Is Hull Resistance

    Resistance is the hulls natural tendency to drag through the water. Bare hull resistance is produced by skin friction of the hulls surface, waves created by the hull running through the water and the shape of the hull below the water. To the bare hull, the drag of appendages must be added such as rudders, shaft support brackets, shafts, depth sounder transducers, stabiliser fins, etc. However, the design of the lift surfaces of the hull also have a very significant effect. Designers work to ensure that the lifting characteristics give the hull the least resistance at normal operating speed.

    Once this resistance is known, engine and gearbox specifications can be combined with maximum propeller diameter to determine the props minimum requirements. The vessels duty cycle, which is simply a judgement as to whether a boat is to be used for heavy or light commercial or pleasure purposes, then also influences a designers final specification.

    Propeller diameter is first decided by the type of boat. A large-diameter slow-revving propeller is the most efficient type but this wont provide the necessary acceleration to get a sports cruiser onto the plane. Acceleration is achieved by increasing the rotation speed, which usually means a smaller diameter propeller. The fact that many modern sports cruisers have limited propeller clearance space is another reason for fitting smaller diameter propellers.

    Tips For Knowing When To Replace Boat Propellers

    How can you tell if your boat propeller requires replacement? There may be an obvious reason for doing so such as if your prop has sustained visible damage to a blade. However, even when your propeller is performing within manufacturers recommended guidelines, often there is room for performance improvement. Reasons for replacement include:

    Close inspection reveals broken or cracked blades. Upgrade to different materials such as aluminum or stainless steel. Upgrade to a different number of blades, from 3 to 4 for example. Upgrade to a larger size boat propeller to improve acceleration and top end performance. Want to carry a replacement propeller on board just in case.

    Select The Right Boat Propellers For Maximum Performance

    The drive train is an important system on any engine-driven vehicle, car, truck or boat. For land vehicles, the system concludes at the tires, where the rubber meets the road. There, the choice is simple: select the right tire for the roadway and intended vehicle use. The difference for water-based craft is, of course, that the drive train ends at the propeller which is the liaison of horsepower to the water. Selecting the right propeller is very important. Boat propellers are available in a wide assortment of sizes and shapes. Sizes are referred to in terms of diameter and pitch. To make the best selection, sync the propeller to the manufacturers wide open throttle range. The right propeller will turn the minimum engine RPMs required by the manufacturer with its throttle fully advanced.

    The next consideration is diameter. This will also determine the propellers RPM capabilities. Overall engine performance can be improved by selecting the right boat prop. The number of blades is also a consideration. Standard rule is the fewer blades, the faster the vessel, however, this rule is not cast in stone. The deciding factor will always be the particular application the boat is used for in order to determine the number of blades required to achieve the best engine performance.

    Prop Size and What to Consider

    You may already know that not all boat propellers are the same. Understanding how they differ in size in important. Prop sizes refer to the diameter or the propeller and its pitch. Boat propellers with smaller diameters are meant for smaller board with smaller engines. As you might assume, larger propellers are designed for maneuvering larger boats. Pitch means how much the boat will move in one revolution. If you purchase a propeller with a higher pitch your boat will move faster as long as the engine is powerful enough to keep the RPMs in the right range.

    Which Material is Best

    How Long Does A Propeller Last

    Like with anything, if you take care of your propeller, it should last the lifetime of your boat. Props do not have an expiration date as long as they arent damaged from impacts with foreign objects.

    This is where knowing how to trim the engine is critical. To trim the engine simply means moving the engine up and down by using the trim function typically found on the throttle.

    If youre in a shallow area, trim the engine up to avoid hitting the propeller on inanimate objects like rocks and lake debris. In deeper spots, you can trim the engine down without the threat of propeller damage.

    Small nicks and dings on the blades are usually no cause for concern, but larger damages should always be inspected by your dealer and either repaired or replaced.

    If you find that the boat has lost acceleration, top-end speed, and has any vibrations that are abnormal, it could be a sign that you need to take a closer look at the prop.
