What is Prop Slip?


Pitch is the distance the propeller/boat progresses thru the water in one complete turn. Every inch of boat that's in the water induces drag, and therefore the distance traveled is not always the same. This results in the propeller "slipping" behind the theoretical distance it should travel with each rotation. The difference between theory and reality is called "propeller slip".


How it works...


Inside the DataTachTM is a computer that receives GPS speed & RPM info and it calculates the slip of your boats propeller. It does this 5 times per second, to give you an accurate reading. See the equation below.

Slip = speed (mph) x 1056 x Drive ratio x 100 RPM x Pitch (in)


A few things that affect prop slip...

Pitch of propeller
Propeller size
Condition of boat bottom
Condition of propeller
Engine mounting height
Weight distribution
Jack plate mounting
Trim angle
You need the DataTach multi-gauge to find out


________________________________________________________________________

The DataTach digital multi-gauge makes it possible -- for the first time -- to record test runs of your boat and capture:


GPS speed
Engine RPMs
Propeller Slip

This synchronized data can then be uploaded to the Propslip.com website from the instrument's removable memory card (like those used in digital cameras), processed, and presented in graph form -- to yield the full performance picture .

The resulting printable graphs are an incredibly valuable tool for boat performance testing.

Use them for:

Comparing test runs
Selecting propeller (share them with you propeller shop)
Keeping tabs on the long-term health of your power train
Optimizing engine set-up
Documenting boat performance prior to buying or selling

Also, the easy-to-use DataTach gauge displays several parameters in real time, including propeller slip -- the ratio (for a given engine speed) of a boat's theoretical travel and it's actual travel, calculated using the parameters of speed, RPM, and propeller pitch (entered once during setup).

The gauge's unique prop slip readout helps you identify the optimum settings for engine, outdrive, trim tab and throttle to deliver maximum performance.

So here are the steps to start maximizing the performance of your boat:
Step 1: Purchase and install the Datatach gauge from Marine Toys
Step 2: While on the water, optimize your boat's performance by making real-time adjustments to minimize propslip
Step 3: Record some test runs, load the resulting data to The website, generate performance graphs, and begin experimenting with your boat's setup to improve it's overall performance.



Maximize the performance of your boat

________________________________________________________________________

The DataTach multi-gauge provides:

Instant feedback (via the gauge's propeller slip display) on how changes in engine trim, drive setting propeller selection, and water/load conditions are impacting overall boat performance.

Performance tracking (using the gauge's optional recording module) of subtle changes that may otherwise go undetected, such as engine and fuel system performance, propeller condition, boat bottom condition, hull design, total load, and weight distribution.
Depending on what type of boating you're in to, this functionality delivers different benefits:

High-Performance Boats: find propeller and engine/drive/tab trim that provide quickest mid-range acceleration and top speed.

Bass Boats: find propeller, engine height, jack plate setback and trim that provide best hole shot, efficiency and top speed.

Offshore Fishing Boats: find the optimal trim setting to maintain propeller "bite" in offshore swells, and maximize range and efficiency.

Flat Boats: find propeller, enging height, setback, and trim that provide quickest time to plane and lowest planing speed.

Runabouts: find propeller, engine/drive trim that provide best all around performance.

Cruisers: find propeller, drive trim and throttle setting that provide the most efficient cruise speed and efficiency
The end result is the knowledge your boat is delivering it's maximum performance, because it's optimally configured to minimize propeller slip (for more information about propeller slip access our free report).

In addition, the performance graphs generated by the website View Demonstration
enable you to:
Compare performance when selling your boat or purchasing your next one.
Share graphs with owners of similar boats to compare performance and find out which setup best suits your performance goals.
Intuitive operation merged with sophisticated technology
