How to calculate propeller slip distance
This calculator finds propeller slip distance by subtracting actual distance traveled from the theoretical distance the propeller's pitch would produce per revolution — a measure of propeller efficiency.
How the calculation works
Slip distance = Theoretical distance − Actual distance.
Example
A theoretical distance of 25 ft per revolution against an actual 21 ft traveled: 25−21 = 4 ft of slip.

Pro Tips for Propeller Slip Distance
- Some propeller slip is normal and expected (typically 10-20% for many boats) since propellers aren't 100% efficient at converting rotation into forward thrust.
- Excessive slip beyond the normal range for your boat/prop combination can indicate an incorrectly pitched propeller or other performance issue worth investigating.
Common Propeller Slip Distance Mistakes to Avoid
- Assuming zero slip is achievable or expected, when some slip is a normal characteristic of propeller propulsion, not necessarily a sign of a problem.
