Marine Propellers and Mercruiser Props – PPT Is Your One Stop Shop For Boat Propellers

** Offering the option between Original Equipment, Direct Replacement, and High Performance OMC Sterndrive engines and Marine Engine Parts **

A unique low -copper alloy gives the ultra economical Aluminum line of Mercruiser props greater strength and corrosion resistance. As far as marine propellers go, investment casting instead of sand or die casting provides greater precision, uniform blade configuration and a smoother finish. Easy to maintain and repair, these boat propellers are also economical and make a great spare.

Call us at (405) 533-3812 or send us an email at sales@perfprotech.com for more details.

Boat propellers seem to be a much overlooked item. However, when it comes to achieving the performance we all desire out of our boat, making sure we get that very last horsepower into the water is of the utmost importance. We will go through a brief explanation of what to look for with propellers.

Propeller Basics

3 Blades vs. 4 Blades
In general the 3 blade propeller offer more speed while the 4 blade offers better thrust and acceleration. Today with the engines producing even more torque, we are starting to see more of the 5 blade products. In general the higher number of blades on a propeller, the lower speed the boat will be able to stay on plane.

Diameter
The diameter is the distance/circle that a propeller makes when rotating.

Pitch
The pitch is the theoretical horizontal distance in inches that the propeller travels when rotated. For example a 23p propeller will travel 23 inches in one revolution (not factoring in slippage).

Rake
Is the angle the blades are tilted towards the rear when measured looking at the side of a propeller. This allows using a larger propeller (more blade area) within the same diameter. Positive rake generally benefits in acceleration and good bow lift.

Cupping
Cupping is a means of simulating addition pitch by "bending" the trailing edges of the propellers to increase the "grip" of the propeller in the water. This feature reduces slippage and is usually used with larger, more powerful engines
