PROPELLER AND GEAR RATIO SELECTION
PROPELLER AND GEAR RATIO SELECTION
Selecting the correct gear ratio and propeller for your application
Choosing the right propeller is the single most important decision you can make to get the best performance
from your OXE outboard engine. Propeller choice can affect boat top speed by as much as 5 to 10 knots. It also
has a direct effect on acceleration, cornering, pulling power, and fuel economy.
An improper propeller choice can significantly affect the performance of your boat and could result in damage
to the outboard engine.
The OXE diesel engine, in comparison to a gasoline outboard engine, delivers a lot more torque at the propeller
shaft and therefor makes it possible to select a larger propeller blade surface area to deliver torque and
maximise performance.
UPPER (PRIMARY) BELT HOUSING
The upper (primary) belt housing is a unique feature of the OXE Diesel. It functions as a quick interchangeable
gearbox. The clever design makes it easy for end users to change gear ratios at the dock or at the shoreline.
By turning the upper belt housing180 degrees, the end user can change the gear ratio between 1:73 to 2:17,
adapting the vessel for heavy or light applications.
A
: High Speed ratio 1.73:1. – Suitable for medium/high speed applications
B
: High Torque ratio 2.17:1 – Suitable for slower heavier applications
1.
Disconnect coolant hoses from the upper belt housing and remove
bolts 1 - 3.
2.
Turn the upper belt housing 180° and remount.
NOTE!
