Mercury Racing Revolution 4 XP propeller offers an extended range of pitches from 13 to 25.5 of the 14-5/8"=14.63" diameter in one-half pitch increments; and 26 to 27.5 pitch range of the 15" diameter in one-half pitch increments.
It also provides extreme precision when dialing-in and fine-tune engine RPMs on multi-engine, stepped-bottom performance center consoles (triple, quad, quint installations) and single-engine bay boats to enhanced throttle response, optimized cruise fuel efficiency, and top speed.
It is well-suited for Mercury Verado 350 and Mercury Racing 400R outboards.
The stainless steel prop features the Mercury patented Performance Vent System (PVS). PVS enables the user to fine-tune the amount of venting needed for quick planing. The standard length exhaust tube, in addition to reducing the time-to-plane, also provides stern lift for maximum hull performance and an improved ride in a variety of conditions. A majority of Mercury Verado, Mercury Pro FourStroke and MerCruiser sterndrive applications will use the Revolution 4 XP with all four vent holes plugged with solid PVS fittings.
Using the XP with the 400R Verado expect 75 to 100 RPM change per one-half pitch. They are designed for performance outboard walleye, pontoon, single or dual center console and some bay boats. It is also used on sterndrive pontoon, deck and sport boats single or dual.
