One thing that each and every boat needs is the optimal boat propeller. Boat props serve to move your boat through the water, however not all boat propellers are the same. In fact there are many different variables that can effect your boats performance when choosing a propeller. The primary factors to consider are the number of blades the propeller has, the diameter of the propeller and the pitch of the propeller. Other factors to keep in mind are the material the propeller is made from, whether the blades are cupped, how much rake is there to the blades and how well are the blades ventilated. One other factor that plays a role in choosing boat propellers is the type of engine your boat has. Below is a bit of information to help you choose a boat propeller based on your engine type or boat usage.
Outboard Propellers - Outboard propellers are those used on outboard engines such as Yamaha, Evinrude, Johnson, Force, Mercury, Nissan, Tohatsu, and Suzuki. Typically these boat propellers are the 3 or 4 bladed variety as these provide the best performance for the size and class of boat that uses an outboard motor. Outboard propellers can be made from a variety of materials, but aluminum and stainless steel are the most common. As with any boat propellers the proper outboard propeller is determined by a combination of diameter and pitch that will allow the boats engine to operate at the manufacturers recommended RPM's when at wide open throttle (WOT). Deep Blue Yacht Supply carries the complete line of Michigan Wheel and SOLAS outboard propellers.
Inboard Propellers - Inboard propellers are those installed on an inboard motor. Inboard propellers are typically constructed of NiBrAl or Bronze materials, with NiBrAl being the optimal material. When choosing a diameter for your inboard propeller you must be sure that it leaves adequate clearance with the bottom of the hull. A general rule of thumb for this is that the clearance should be equal to 20% of the diameter of the propeller. So a propeller with a diameter of 20 inches should have at least 4 inches clearance. If this become a problem a propeller that is 1-2 inches smaller can be used with a corresponding increase in pitch to maintain engine efficiency. Deep Blue Yacht Supply stocks the complete line of Michigan Wheel inboard propellers.
Sterndrive propellers - Stern drive engines are widely regarded as one of the great improvements in the recent history of boating. Stern drive props are able to be trimmed with controls at your fingertips. This can result in better fuel efficiency, safer shallow water boating and better handling in rough waters. Stern drives have the rudder built in providing much better control, especially when docking. The major downside of stern drives is the high cost of maintenance due to the fact the often the engine must be removed to work on parts that are in a space that is too small to access. Deep Blue Yacht Supply carries the complete line of Michigan Wheel and SOLAS boat propellers, and is able to provide props for OMC, Volvo Penta, Yamaha, and MerCruiser sterndrive engines.
Ski Propellers - When choosing ski boat propellers some of your decisions have been made for you based on the type of boating you will be doing. For example, you will often want a lower pitch to increase your hole shot speed and get the skiers up out of the water as quickly as possible. Hole shot speed and quick planing are two extremely important performance variables when selecting the best propeller for your boat. Afterrmarket ski boat propellers routinely outperform stock propellers from hole shot to top end, which is why so many ski boat owners select ACME or Ambush ski propellers. Deep Blue Yacht Supply is the marine industry leader when it comes to supplying ACME and Ambush ski props.
Volvo Duo propellers - The Volvo Duo propellers revolutionized propellers when they were introduced in 1982. These revolutionary boat propellers provide boaters with increased bite in the water, faster acceleration combined with better fuel efficiency, less vibration and noise, quicker planing and improved maneuverability. Designed as two counter rotating blades with the end result being the engines power is directed at driving the boat forward rather than sideways due to lateral forces that can act on conventional single propeller stern drives. The Volvo Duo propellers are available in a wide variety of sizes and materials depending on your engine and boating needs. Deep Blue Yacht Supply is the price and service leader when it comes to Volvo Duo Props, and stocks the complete line.
The Need for Aftermarket Boat Props
Those who are new to the leisure activity of boating may not be aware of one key fact about outboard propeller engines. In most cases, the propeller that ships with an outboard engine is a “stock” part and is not, in fact, the ideal propeller for every boat that may elect to include that particular type and model of outboard motor. Stock boat propellers such as these tend to be designed along “compromise” principles that will allow the motor to be used with a large number of different boats.
Depending on the hull and load that the motor must eventually contend with, however, these boat props may range in performance from average to unsatisfactory. The solution to this problem is to look at the range and variety of aftermarket boat propellers instead. Choosing the correct propeller for a specific boat and engine will allow the engine to run properly at its rated horsepower, which is usually marked clearly on the engine cover.
Outboard engines are supposed to be able to run at their maximum rated revolutions per minute – this situation creates peak efficiencies. The wrong propeller can cause an engine to run at an exceptionally high RPM. This leads to faster wear and tear on engine parts because it creates additional friction. Too few revolutions per minute are also inadvisable since it causes carbon build-up as well as poor fuel utilization. The right boat propeller, however, can help boaters to avoid both of these situations so that they can derive maximum use and pleasure out of their watercraft.
Changing Your Boat Prop
Boating enthusiasts know that for all the wonderful times and adventures they have on their water craft, there is also a maintenance aspect that must be considered. One periodic task that must be taken care of is changing out an old propeller for a new one. This is not a frequent job; it needs to be done only when the existing propeller shows serious signs of wear or when it has been subject to an accident or some kind of malfunction. Of course, some boaters also change their propellers simply to get better performance from their water craft.
Boat Propeller Pullers: A Handy Tool
The most useful tools a boater could have in this situation include boat propeller pullers. With such a tool, the task of removing the old propeller becomes much simpler.
How to Use a Boat Prop Puller
Using boat prop pullers is not difficult, but for the job to go well, it requires a little advance planning. First, take a pencil and use it to mark where the old propeller lies in the propulsion system. You will use this mark later to make sure that the new propeller is seated in exactly the same location.
After that it is time to get the old propeller ready to remove. The first step is to turn the propeller slowly while you hold on to a ratchet around the retaining nut. Do not loosen the nut 100 per cent of the way. When the propeller is loose, it is time to use the prop puller, which is used to remove the existing propeller from the shaft it normally sits on.
Lesser-Known Outboard Propeller Terms
Most people understand the difference between diameter and radius, but other terms that are used to describe outboard propellers may be less familiar to the general population and may even cause confusion among boating enthusiasts.
Terms Used to Describe Pitch
There are several ways, for example, to describe the pitch characteristics of outboard boat props. Pitch itself refers to the distance that a single full revolution of the propeller will cause it to move through a stable medium such as a soft wood. Some outboard propellers, however, can be described as having a propeller that features “controllable pitch.” This means that the propeller blades are each mounted separately onto the central hub. Each has its own axis of rotation, which means that pitch can be changed.
A fixed pitch propeller, on the other hand, features propeller blades that are mounted permanently and exhibit a fixed axis of rotation so that pitch is not adjustable.
It may be tempting to equate fixed with constant, but when it comes to propeller pitch, the terms are not interchangeable. A constant pitch propeller is one in which the propeller blades themselves are engineered to have a constant value of pitch from one end to the other – in other words, from their roots to their tips and from their trailing edges to their leading edges. The opposite of a constant pitch propeller is a variable pitch propeller. In this arrangement, each section of a propeller blade may have different pitch values from the other sections.
