## How do I know what gear ratio I have outdrive?

The numerical ratio is calculated by dividing the number of teeth on the meshed gear, or gear with the large number of teeth (output) by the number of teeth on the input drive gear, or gear with smaller number of teeth (output # / input # = x).

## How do you calculate gear ratio speed?

To calculate speed ratio, otherwise known as gear ratio, you divide the number of teeth of the input gear by the number of teeth of the output gear.

## How do I find the best gear ratio?

How to Choose Your Axle Gear Ratio –

## How do you find the gear ratio on a cobra outdrive?

The numerical ratio is calculated by dividing the number of teeth on the meshed gear, or gear with the large number of teeth (output) by the number of teeth on the input drive gear, or gear with smaller number of teeth (output # / input # = x).

## What is outboard gear ratio?

The lower unit Gear Ratio and its importance. This is due to the reduction gear which exists on all the outboard engines among their crankshaft and propeller shaft. Gear ratio (or reduction ratio) is expressed by the number of crankshaft revolutions for one revolution of the propeller.

## How do I calculate RPM?

Calculating the RPM for your machines –

## What is the ratio of speed?

Speed Ratio Definition

When the first gear (the driver or input gear) turns, the second gear (the driven or ouput gear) turns in response. The difference between the speeds of the two gears is called the speed ratio or gear ratio.

## What is the ratio of velocity?

Velocity ratio is also defined as the ratio of a distance through which any part of a machine moves, to that which the driving part moves during the same time. An object has a mechanical advantage if it exerts a force higher than the velocity ratio.

## What is the difference between 3.73 and 4.10 gear ratio?

Use this rule of thumb: The higher the gear ratio, the easier it is to get the vehicle moving and better accelerating, but lowers top speed. Vice versa, if the gear ratio is lower it has worse acceleration but a higher top speed.

WHICH GEAR RATIO IS FOR YOU?

3.73 RATIO | 4.10 RATIO |
---|---|

Higher top speed | Lower top speed |

## What is the difference between 3.73 and 4.10 axle ratio?

A 4.10 rear axle ratio is ideal for towing larger 5th Wheel or Gooseneck trailers. FACT: A 3.73 axle ratio is ideal for towing heavy loads on flat terrain and will produce increased fuel economy during steady-state, long-distance highway driving.

## Is it better to have a higher or lower gear ratio?

The lower the number, the faster the car will go with the same number of engine revolutions. The higher the number the better the car will accelerate, but at the expense of high speed cruising. Now for the confusing part of the story. A high numerical gear ratio is called a low gear or low rear end, and vice versa.
