VIF Jason Marine Upgrade OEM 13 Spline Aluminum Outboard Propeller

In this review the VIF Jason Marine Upgrade OEM 13 Spline aluminum propeller is evaluated for owners of Mercury 30-70hp outboards who want an OEM-style replacement that improves speed and installs easily. The bottom line: this propeller delivers a noticeable uptick in top speed and smooth operation for many users while maintaining an OEM fit with a 13 spline hub, making it a practical upgrade for recreational boaters seeking better acceleration and fuel efficiency without major changes to their drive train.

Key Features

• OEM Compatibility: Designed for Mercury outboard engines 30-70hp with a 13 spline tooth hub, it fits like an original part and reduces installation hassle.
• Aluminum Construction: High quality aluminum offers a balance of light weight and durability so the propeller maintains speed and responsiveness.
• Multiple Pitch Options: Available in sizes and pitches such as 10 3/8 x 13p, 11 x 15p and others, allowing owners to select a pitch that improves top speed or acceleration for their setup.
• Right Hand Rotation: The RH, 3-blade design provides predictable handling and consistent thrust for common recreational applications.
• Preinstalled Hub Kit: Propellers ship as pictured with hub kits installed, simplifying fitment and saving time during replacement.

Who It's For

This propeller is best for Mercury outboard owners who need a one-for-one OEM style replacement for 30-70hp engines and want an economical way to recover or improve top speed and acceleration. It is particularly well suited to anglers and weekend boaters who value simple installation and multiple pitch choices for tuning performance.

Boaters who need heavy-duty impact resistance for frequent shallow-water use, commercial operators, or those who demand cast stainless steel longevity should consider heavier-duty or alternative materials, since aluminum offers good performance but can be less durable under extreme conditions.
