INSTALLATION INSTRUCTION
5. 10. ELASTIC SHAFT COUPLING
For engines with elastic suspension and a rigid stem bushing, an elastic shaft coupling is always to be mounted.
Even for a rigid engine suspension, an elastic propeller shaft coupling should be mounted if there is any risk that
the engine may change its position with regard to the propeller shaft, e.g. with different load of the boat.
Never use the elastic shaft coupling together with the elastically supported stem bushing. This may result in heavy
vibrations. Elastic engine suspension and elastically supported shaft bushing may, however, be used without
elastic coupling.
Engines provided for operation under heavy conditions, e.g. way through ice, are always to be equipped with
elastic propeller shaft coupling. A special thrust bearing for the propeller shaft is also to be mounted. The elastic
coupling should be situated between reversing gear and thrust bearing, to avoid tensions between the parts.
5.11. STEP BEARING
If the distance between the supports (a in ill. 12 and 13) exceeds 6 1/2 ft (2 m), a step bearing is to be mounted.
The correct distance between the step bearing and the engine is of utmost importance, which requires a
computation of vibrations.
