VIF Jason Marine 13 Spline Aluminum Outboard Propeller - Fit Mercury

In this review the VIF Jason Marine 13 spline aluminum outboard propeller is evaluated for owners of Mercury outboard engines between 25hp Bigfoot and 60hp models who need a direct-fit replacement with a variety of common pitch options. The bottom line: this propeller is a practical, budget-friendly OEM-style replacement that matches several factory dimensions and spline counts, making it the simplest route to restore thrust and handling after a damaged or worn propeller. It is especially useful when a reliable 3-blade, right-rotation prop is required that fits a 3-1/4' gearcase with a 13-spline shaft.

Key Features

• 13-spline tooth fit: Matches the factory 13-spline shaft pattern used on many Mercury 25-60hp engines so installation is straightforward without modifications.
• Multiple pitch options: Available in a range of OEM-equivalent pitches such as 10 3/4' x 12' and 10 3/8' x 13' so buyers can select the pitch closest to their original for similar performance.
• Aluminum construction: Lightweight aluminum blades deliver reliable acceleration and responsive handling while remaining cost-effective to replace if struck or bent.
• Right-hand rotation, 3 blades: Standard right-hand rotation and three-blade design balance top speed and hole-shot, suitable for a variety of small to mid-size powerboats.
• 3-1/4' gearcase diameter compatibility: Specifically sized for the common 3-1/4' gearcase used on the listed Mercury models, reducing the chance of fitment confusion.

Who It's For

The VIF Jason Marine propeller is aimed at boat owners with Mercury outboard engines from the 25hp Bigfoot (4-stroke) up through 60hp models who need a like-for-like replacement without changing gearcase or shaft. It is a practical option for weekend anglers, small utility boats, and owners restoring factory performance after damage.

Those seeking a high-end performance prop, stainless steel construction, or specialized blade geometry for racing or heavy-load commercial use should look elsewhere, since this product is positioned as an OEM-style aluminum replacement rather than a premium aftermarket performance propeller.

Pros & Cons

Pros

• Direct 13-spline fit for many Mercury engines makes installation simple and reliable.
• Multiple OEM-equivalent pitch choices allow matching original thrust and top speed closely.
• Aluminum 3-blade design gives a good balance of acceleration, handling, and value for recreational use.
• Sized for the common 3-1/4' gearcase used on specified models, reducing fitment errors.

Cons

• Aluminum construction is less durable than stainless steel and may bend or ding from impacts more readily.
• Not intended for specialized high-performance or heavy commercial applications.

Specifications

Our Verdict

The VIF Jason Marine 13-spline aluminum propeller is a sensible, cost-effective replacement for owners of compatible Mercury outboards who want to restore factory-like performance without extra fuss. It brings the right spline count, common OEM pitch options, and a standard 3-blade, right-rotation layout that suits most recreational boats; choose a stainless alternative only if you need greater impact resistance or advanced performance gains.

Frequently Asked Questions

Will this propeller fit my Mercury 30hp engine?
If your 30hp Mercury uses a 13-spline shaft and a 3-1/4' gearcase as listed for certain 30hp models, this propeller is designed to fit those configurations.

What pitch should I choose?
Match the pitch to your original OEM pitch when possible; available options include 10 3/4' x 12' and 10 3/8' x 13' among others to approximate factory performance.

Is the propeller stainless steel?
No, this model is aluminum construction; it is lighter and less costly but will not resist impacts as well as stainless steel.
