( Manufacturer Part Number: TT284-TT285 ), ( Part Type: Blade Propeller Prop Wheel )
The 1-1-2 18 nibral blade propeller is an exceptional inboard wheel propeller designed for high-performance applications. This propeller is specifically engineered for use with the Tohatsu TT284 and TT285 outboard engines, making it an ideal choice for boat owners looking to maximize their engine's potential.
The propeller features a 18-inch diameter and a 22-inch pitch, providing excellent thrust and acceleration. The 1-1-2 configuration, which refers to the number of blades, is known for its balance and efficiency, allowing the propeller to generate consistent power while minimizing vibrations and noise.
The blades of this propeller are crafted from nibral, a corrosion-resistant alloy that combines nickel, manganese, and aluminum. This material ensures that the propeller can withstand harsh marine environments and maintain its performance over time, even in saltwater.
The 1-1-2 18 nibral blade propeller also features a three-blade design, which is favored for its balance, efficiency, and ability to generate a strong pull. The blades are carefully shaped for optimal performance, with a concave curve that provides lift and thrust while minimizing drag.
In terms of installation, the propeller is designed to fit most standard inboard wheel applications. It comes with a 2-inch hub and a 2-inch-diameter key for easy installation and removal.
Overall, the 1-1-2 18 nibral blade propeller is a high-quality, durable, and efficient propeller that is well-suited for use with the Tohatsu TT284 and TT285 outboard engines. It provides excellent acceleration, balance, and corrosion resistance, making it a top choice for boat owners who demand the best performance from their propellers.
Pros of buying a 1-1-2 18 nibral blade propeller prop for inboard wheel setup (18x22 tt284 tt285):1. Durability: Nibral is a high-strength alloy that is resistant to corrosion, making this propeller a long-lasting option.
2. Efficiency: The 3-blade design of the propeller provides better efficiency, which can result in improved performance and fuel efficiency.
3. Fitment: This propeller is specifically designed for the tt284 and tt285 outboard engines, ensuring a proper fit and optimal performance.
Cons of buying a 1-1-2 18 nibral blade propeller prop for inboard wheel setup (18x22 tt284 tt285):1. Price: Nibral propellers tend to be more expensive than alternatives made of materials like aluminum or stainless steel.
2. Limited size options: The 1-1-2 18 nibral blade propeller is only available in one size (18x22), which may not be suitable for all boat types or power requirements.
Conclusion: If you're looking for a durable, efficient propeller for your tt284 or tt285 outboard engine and are willing to invest in a higher-end propeller, the 1-1-2 18 nibral blade propeller prop is a solid choice. However, if budget is a concern, you may want to consider alternative materials or propeller designs that offer similar performance at a lower price.
After I reconditioned the originals keep these in case needed them again. I don't remember the manufacturer but model numbers on props are TT284, TT285 compare at these were boat and in water for 2 years. Had to use them after I hit a 6x6 and bent my originals.
Used 18x22 nibral propellers. I bought these years ago for my sea ray as a spare set. For a brand new set.
They worked nicely while I had them on and no issues.
