About This Propeller

The Mercury Revolution 4 is a premium 4-blade stainless steel propeller engineered for outboard and sterndrive applications where acceleration, stern lift, and rough-water control matter more than outright top speed. The fourth blade adds blade area compared to a 3-blade prop, which translates to stronger grip on the water, reduced ventilation in turns, and better performance with heavy loads or in choppy conditions. The built-in PVS (Performance Vent System) allows fine-tuning of hole shot performance by adjusting the amount of exhaust venting through the hub — a feature that lets you dial in launch performance for your specific boat and load.

The Revolution 4 uses Mercury’s Flo-Torq hub system. The propeller shell does not include the hub insert — a compatible Flo-Torq hub kit must be ordered separately based on your engine and shaft configuration.

Compatible Applications

Mercury / Mariner Outboards:

• Mercury 135–350 HP Optimax, Verado, and FourStroke outboards
• Mercury 90–115 HP Command Thrust / BigFoot (2014 and newer)

MerCruiser Sterndrives:

• MerCruiser Alpha One sterndrive
• MerCruiser Bravo One sterndrive
• MerCruiser TRS drives

Hub kit selection depends on prop shaft diameter (1.0" vs 1.25" are common) and engine configuration. Always confirm the correct Flo-Torq hub kit for your engine before ordering. Contact us with your engine model and serial number if you need help selecting the right hub.

Performance Characteristics

• Strong hole shot and acceleration — the 4-blade design grips the water harder off the line
• Excellent stern lift for heavy boats, loaded vessels, and offshore applications
• Reduced ventilation and blow-out in hard turns compared to 3-blade props
• Better control and stability in rough water or when running with heavy loads
• Ability to keep boats on plane at lower speeds — ideal for towing or slow trolling
• PVS vent system allows adjustable hole shot tuning without changing props

Note: 4-blade propellers typically offer slightly lower top speed compared to a comparable 3-blade prop of the same pitch. The trade-off is improved handling, grip, and mid-range performance.

Ideal Boat Types

• Center consoles and offshore fishing boats
• Deep-V hulls running in rough or open water
• Heavy boats that need improved stern lift to get on plane
• Boats used for watersports, towing, or carrying variable loads
• Vessels where ventilation or blow-out in turns has been a problem with a 3-blade prop

Pitch Selection Guide

The 17-pitch version of the Revolution 4 is a mid-range pitch suited to engines in the 135–200 HP range on typical planning hulls. As a general rule, each inch of pitch change affects wide-open-throttle RPM by approximately 150–200 RPM — lower pitch raises RPM, higher pitch lowers it. Your engine should reach its rated WOT RPM range with the correct prop. If you’re unsure which pitch is right for your setup, contact us with your engine HP, boat weight, and typical load.

Hub Kit Requirement

The Revolution 4 shell requires a separate Flo-Torq hub kit to mount to your engine. The correct hub kit depends on your engine model and prop shaft diameter. See the related parts below for available Flo-Torq hub options, or contact us to confirm the right kit for your application.

Technical FAQ

Does this propeller include the hub?
No. The Revolution 4 shell is sold without the hub insert. You must order a compatible Flo-Torq hub kit separately. The hub kit required depends on your engine model and prop shaft diameter. See the related parts above or contact us to confirm the correct hub for your application.

Will a 4-blade prop slow my top speed?
Typically yes, by a small margin — usually 1–3 mph compared to a 3-blade prop of the same pitch. However, the gains in hole shot, stern lift, rough-water handling, and reduced ventilation make the Revolution 4 the better choice for most fishing, offshore, and heavy-load applications where top speed is not the primary goal.

How do I know if 17 pitch is right for my engine?
Check your engine’s rated WOT RPM range in the owner’s manual. With the correct prop, your engine should reach that RPM range at wide-open throttle with a typical load. If RPM is too high, go up in pitch; if too low, go down. Each inch of pitch change moves RPM approximately 150–200 RPM.

What is the PVS vent system and how do I use it?
The Performance Vent System (PVS) consists of small holes in the prop hub that allow exhaust gas to vent through the hub during acceleration, reducing load on the engine for a faster hole shot. Plugging the holes reduces venting for better top-end grip. Mercury supplies plugs with the prop — experiment with plugged vs. unplugged to find the best setting for your boat and load.

Parts Desk Insights

Best use case: The Revolution 4 in 17 pitch is the right choice for boaters who want better hole shot, stern lift, and rough-water control on a mid-range outboard or sterndrive — particularly on heavier center consoles, offshore fishing boats, or any application where a 3-blade prop has been ventilating in turns or struggling to get the boat on plane. It’s a significant upgrade over aluminum props and a strong performer for mixed-use boating.

Common issues: The most frequent issue is customers ordering the prop without confirming the correct Flo-Torq hub kit — the prop cannot be installed without the hub, and the wrong hub will not fit. Always confirm the hub kit at the time of ordering. A second common issue is pitch selection — customers sometimes choose pitch based on their old prop rather than checking WOT RPM, which can result in an over- or under-pitched setup. Encourage customers to verify their engine’s WOT RPM range and current RPM with their existing prop before selecting a pitch.
