How To Find Gear Ratio On Mercury Outboard? Held to a Higher Standard. There are plenty of good reasons these outboards rule the water. Start with no-worry reliability. More low-end torque for excellent acceleration.. Tower, You forgot to add that the higher gear ratio will give higher top speed, if the motor has the power for it. The real reason for the different gear ratios is to allow the. The ratios in modern Mercury lower units are 2.0, 1.87, 1.75 and 1.62. These are based on the propshaft's "ONE" revolution! E.G. 2.0:1, 1.87:1, 1.75:1 and 1.62:1. In.
Finding the gear ratio on your Mercury Outboard can be a tricky task to undertake. However, with the right resources and step-by-step guide, you can easily and accurately determine your outboard’s gear ratio.
The gear ratio is the ratio of the number of teeth on the pinion gear to the number of teeth on the drive gear. The ratio helps you determine the speed ratio between the two gears. This is important to know because it affects how your outboard will perform in the water.
To find your Mercury Outboard’s gear ratio, follow these steps:
- Remove the lower unit of the outboard motor. Locate the pinion gear and the drive gear.
- Count the number of teeth on the pinion gear and the drive gear.
- Divide the number of teeth on the pinion by the number of teeth on the drive gear. For example, if the pinion gear has 12 teeth and the drive gear has 24 teeth, the ratio is 0.5.
- Write down the gear ratio and compare it to the recommended gear ratio for your outboard motor.
It is important to make sure the gear ratio you have determined is the same as the recommended gear ratio for your model of outboard motor. If it is, then you have correctly identified the gear ratio. If the ratio is different, then you may need to purchase a new pinion and/or drive gear.
To make sure you are replacing the correct parts, you should consult your Mercury Outboard’s owner’s manual for the recommended gear ratio for your model. This will ensure that you are replacing the correct parts and that your outboard will perform optimally in the water.
In conclusion, determining the gear ratio on your Mercury Outboard can be an intimidating task. However, with the right resources and a step-by-step guide, you can easily and accurately determine the gear ratio of your outboard motor. Just make sure to consult your owner’s manual for the recommended gear ratio for your model before replacing any parts.
