What causes prop slippage?
There are many factors that affect prop slip including the actual pitch of the propeller, the condition of the propeller, the design of the hull, the condition of the bottom of the craft, additional weight on the craft, distribution of weight, height the engine is mounted at, engine trim angle and setback, jack plate …
Why is my prop slipping?
Prop slip occurs when a prop fails to achieve its power potential. This is due to resistance from the water that prop is working to propel the boat through. As the prop endures the resistance, it tends to slide back and does not go the actual full distance in that one revolution.

How do you fix a prop slip?
Calculate Propeller Slip: RPM div by GEAR RATIO x PITCH div by 1056 = Theoretical Speed. Then you divide the customers actual (gps) speed by the Theoretical speed to get propeller efficiency. For Example: 5500 div by 2.07 x 20 div by 1056 = 50.23mph.
What is a spun propeller and how to fix it?
by Kevin Mclain. A spun propeller means that the prop hub has spun inside the propeller. Once the hub spins inside of the propeller, the propeller will spin freely and not along with the hub. A hub can spin inside of a prop due to damage to the hub, damage to the inside diameter of the propeller or incorrect propeller installation.
How do I know if my prop hub has been spun?
You will likely feel the prop slipping at high RPM. Sometimes, the hub only spins when the engine revs above a certain RPM, causing many boaters to wonder if they have spun a hub, are experiencing ventilation or cavitation, or have some kind of gear or power issue with their outboard.
