NOVINO Boat Propeller 14x17 RH 4-Blade for Mercruiser Alpha/Bravo One

In this review the NOVINO 14' x 17' right hand, 4-blade aluminum propeller is evaluated for owners of Mercruiser Alpha One/Bravo One stern drives and Mercury outboard engines from roughly 135 to 300 HP. The bottom line: this propeller is aimed at boaters who need a rugged, corrosion-resistant replacement that restores acceleration and top speed while offering simple installation steps. The reviewer found it especially useful for planing boats and for users who want a durable, budget-friendly spare that closely matches the original equipment fit and performance.

Key Features

• 14' diameter x 17' pitch: Provides a balance of acceleration and top speed suited to many 135-300 HP Mercury and Mercruiser applications.
• 4-blade aluminum construction: Heavy duty, corrosion-proof aluminum and heat-treated blades that resist wear and offer steady handling in choppy water.
• Right hand rotation, 15 spline: Matches common OEM shaft splines and rotation for direct replacement on compatible drives and outboards.
• OEM replacement fit: Designed to replace part no. 48-8M0084494 and fit Alpha I/Bravo I stern drives and specified Mercury outboards, reducing fitment guesswork when specs match.
• Improved fuel efficiency and speed: Customers reported lower fuel consumption and quicker acceleration after fitting, which helps reduce engine strain.

Who It's For

This propeller is best for owners of Mercruiser Alpha One or Bravo One stern drives and Mercury outboard engines in the 135-300 HP range who need a cost-effective replacement that restores original handling and speed. It suits recreational boaters who tow tubers or skiers and want a propeller that helps the boat plane earlier and hold steady in chop.

Boaters who require a specific hub type should note this propeller does not include a Flo-Torque hub kit, so anyone needing that dampening system or an exact OEM hub should look elsewhere or plan to reuse an existing hub. Also confirm diameter, pitch, rotation and OEM number before buying.

Pros & Cons

Pros

• Easy installation with straightforward steps for customers familiar with prop removal and reassembly.
• Solid build and corrosion resistance from heat-treated aluminum blades for long service life in salt or fresh water.
• Notable performance improvement in acceleration and planing according to customer feedback, especially when pulling riders.

Cons

• Does not include the Flo-Torque hub kit, so buyers needing that component must purchase it separately.
• Fit depends on matching diameter, pitch, rotation and OEM number exactly, which can be confusing for less technical users.
