When you start looking for a new boat prop you go on-line and search boat propellers to see what is available for your engine. If you have never bought a boat propeller before you will see that the sizes are shown with two numbers not just one. You will see 10 1/8 x 14 or 14.5 x 19 and a bunch of other sizes that make you wonder what do these numbers mean? Well it is really very simple. The first number is the diameter of the boat propeller and the second number is the pitch. First I’ll give a brief definition of pitch and the rest of this blog will focus on diameter.
The next blog will be about pitch. The easiest explanation about pitch is that it is how far a propeller will travel forward through a solid one revolution in terms of inches. A 14 pitch prop will go 14 inches forward in one turn and a 19 pitch prop will go 19 inches forward in one turn.The definition of a boat propellers diameter is a measurement from the center of the propeller shaft hole in the center of the prop out to one blade tip then multiplied by two. For example, if you measured from the center out to one tip and got a measurement of five and one sixteenth inches then the diameter of you propeller is 10 1/8 inches. If you measured seven and one quarter inches then you have a 14. 5 diameter prop.
The smaller the outboard motor in terms of horsepower, the smaller the diameter of the boat prop is. And the bigger the motor is the bigger the diameter of the prop is. The reason for this is that you cannot use a huge diameter prop on say a twenty horsepower engine because it would be trying to bite way too much water for the little horsepower engine to handle and it would bog down the engine so much that the boat would hardly move. The opposite effect would happen if you put a real small diameter boat propeller on a large horsepower engine. The prop would just pretty much free spin at a high rate of speed because it’s not biting enough water to push the boat and the engine would rev way up and the boat would hardly move.
What diameters work best for what engines and for different pitches is determined by the propeller manufacturer through research and development witch means just trial and error on what diameter gives the best performance for a certain pitch.

Turning Point safer boat propellers were developed since every year there are thousands of injuries and even deaths caused by boat propellers cutting people and sea life in all kinds of waterways.
Many injuries happen to people who are in the water behind the boat and close to the boat propeller when the driver puts the propeller in gear to get under way not realizing someone is back there and they are run over and cut up. Regular boat propellers can cause very severe cuts because it is spinning so fast.
Turning Point Propellers has teamed up with Colin Chamberlain the inventor of the ESP Safer Prop and is now offering boat props that can minimize the damage of these propeller strikes at low speeds to people, marine mammals, turtles and other sea life. This new model line is the result of ten years of intensive research and development and are called Aegis Propellers. They are stainless steel propellers that have a green multi-coat paint finish for better visibility under water. Under the green coat they have a red coat that shows when the propeller gets damaged and the green paint is scraped off. This is a great visual aid to see that damage has occurred to the boat prop.
These new boat props are available a variety of sizes for 25 horsepower bigfoot outboards all the way up to 300 plus horsepower outboards and sterndrives in all engine brands. They are all three bladed right hand rotation stainless steel props.

Stern Lifting Propellers or Bow Lifting Propellers?
What type of boat propeller would work best for your boat? It depends on a few things. Type of boat is one and how you want to use it is another. For high powered light bass boats you want the most speed you can get ,that means a three blade prop with a higher rake degree. This type creates the most speed. Three bladed boat propellers with a high degree of rake are generally faster than a four bladed propeller. Four bladed propellers actually give better stern lift and less bow lift even if it has a high rake degree simply because the extra blade. If you have a sterndrive family style boat, a stern lifting prop is most popular because sterdrive boats are stern heavy and need help getting up and on top of the water quicker.
The Jetovator is kind of hard to explain exactly what it is.No boat propellers on this jet powered craft. This thing is something different to say the least. It is a rideable water toy that depends on a jet powered PWC for propulsion. It does not have it’s own power source. You connect a sixty six foot hose that is attached to a PWC to the Jetovator, then the PWC rider uses his throttle to supply water jet pressure to the Jetovator operator who then can use his controls to elevate out and above the water as high as forty feet and can also maneuver turns. Speeds up to twenty five MPH can be obtained. It’s a team effort used here because the PWC and operator are actually towed by the Jetovator operator as he goes forwards, backwards, up and down and turns right and left. Pretty neat ride experience like no other.
You might be thinking the price of this thing is probably outrageous because there is nothing like it and it has no competition. But considering how much fun you can have with it, the manufactures suggested retail price of $5,975.00 really is not a lot of money. There are some options you can get that will add to the cost but they are not too expensive. For more information on the Jetovator go to www.jetovator.com.

Using jet drives, instead of boat propellers, there is a very different and amazing type of marine craft called the Seabreacher you can buy that maneuvers and looks more like sea creature than a boat. It can dive under the water and then pop up and fly out of the water just like a fish at speeds up to twenty miles per hour underwater and up to sixty miles per hour on top of the water. They use jet drives instead of boat propellers and three models are available at the moment with more in the works. The speed and maneuverability of these watercraft will give you a water thrill ride like you never had before.
Seabreacher X,Y and Z models look a lot like a shark, killer whale and a dolphin. The X and Y models are two person models. The Z model is a one person model. All three are about seventeen feet long with a body width of three feet and a wing span of six and a half feet. The cockpit is water tight with a high visibility plexiglass canopy so you stay dry diving underwater.
All three are powered by a quiet Rotax 1500cc four stroke supercharged engine that is rated at 260 hp. They weigh about 1450 lbs. Fuel capacity is fourteen gallons. The price tag on these watercraft with trailer range from $80,000 to $100.000 depending on the options wanted. Shipping charges are extra.

If your boat propeller need repair, you are right, boat propellers can be repaired. If your boat prop looks like it has damage on the blades or if the blades look like they are bent you need to have the propeller repaired. If the blades look just a little frayed on the edges and you do not notice any loss of performance or vibration caused by not being balanced you might be ok to use it but if you have a bigger boat you may not feel vibration. It will be kind of a judgement call in that case on whether to get it repaired or not. You can file off the burred edges a little which might make it more usable. Many boat dealers are hooked up with boat prop repair shops so you can call them and ask if they are and if so take your prop to them and they will have it sent out for repair and then have it returned to them. Some prop shops will deal with the public so you can maybe contact them yourself.
If your boat prop seems to just rev up and not go anywhere your hub is most likely spun and needs to be replaced. Boat propellers made out of aluminum and stainless steel have center hubs that are designed to break away from the inner wall of the propeller and spin inside it apon an impact. If you have a prop that has a rubber hub installed at the factory you need to take it to a propeller repair shop and have them press out the old hub and press in a new one. This is something a professional should do, not you, because the hub has to be positioned in the boat propeller just right and balanced. If you have a removeable hub system all you need to do is tap out the damaged plastic or rubber coated insert and go get a new one from a boat dealer that handles your brand of engine and push that in your prop yourself.

You are out enjoying the day on the lake in your boat with your family or friends just putting along near shore when all of a sudden it feels like your boat hit a pothole and your engine and or lower unit has vibration problems. What happened? Your drive systems lower unit and propeller ran aground and your boat prop blades are now damaged and don’t work right anymore. This is how most boat propellers get damaged. It can be avoided if you have a depth finder system on your boat.
Depth finders are a great way to know how close the bottom of the lake is to the bottom of your boat. And they have sounding alarms you can set at a certain depth that warn you how close you are to hitting bottom. They are a simple sonar that uses an electronic sending and recieving signal device called a transducer that is mounted either on the stern of the boat as low as posible or inside the boat in the bilge erea known as a through hull transducer. Electronic signal pulses are shot down and bounce off solid objects and then are returned to the transducer. The time it takes for the signal to return is then turned into a calculation in feet or yards of what the distance is between the solid object and the transducer. That distance information can then be shown on a display mounted on or in your dashboard. You do not have to be going slow for depth finders to work. They also work at all speeds of your boat but if you are going fast and all of a sudden the depth alarm goes off it might be too late to avoid hitting something. You can set the alarm to sound at a greater distance that can give you more time to react but if you are not sure about the erea of water you are in slow down so if the alarm does go off you have time to stop or steer clear of danger.
If you do not have a depth finder but want to get one installed on your boat you should have a professional install it for you. It is not really a do it yourself project. The positioning of the transducer is most important so it can accurately send and recieve signals.
