Aluminum is the most common of metals used in casting boat props. Aluminum boat props are painted to prevent corrosion. They are lightweight, high performance and cost effective propellers. Aluminum boat props are best used in small boats. They are easily available and portable.
There are props of every size, pitch, material and number of blades available at a discounted price. Some websites offer discount and gift coupons for the propellers listed. It is always advisable to keep a spare propeller for. Emergencies and purchasing a spare propeller at a marked down price will make budget friendly sense. Discounts are available on props made by renowned companies and there is no need to compromise on quality when purchasing a marked down prop.
The benefits of using aluminum props are that they are cheaper than their stainless steel counterparts. They are available in all sizes, pitches and diameters. Two, three and four blade props are available. They are the ideal spare prop for emergency repairs. When aluminum propellers hit obstacles, they break but protect the engine system and the other motor units. Aluminum will not damage gears of the boat if it is left idle or set too high. All major motor manufacturers manufacture aluminum props. Small leisure boats with outboard motors use aluminum props to protect the motor and for easy replacement in the event of a collision with an obstacle. Aluminum is a rigid metal compared to stainless steel and can withstand damage better.
Aluminum props are not as durable and strong as stainless steel props. It is not easy to cast innovative designs and as a result the range of designs that stainless steel props have are not available for aluminum props. Aluminum needs to be painted with anti corrosive paint because it is not resistant to corrosion. Stainless steel will not corrode in salt water but aluminum is not resistant to brine. A choice of aluminum props can be purchased online and in boat accessory stores.
