Thrust Output Drive (TOD)

Fitting for all inboard motor HP 150 ~ 350 power output


This product is for conventionally driven vessels. The system uses a constant velocity joint to self-align the shaft. Thrust taken up on the engine from the propeller invariably changes the angle of the shaft line, particularly when the engine uses soft rubber mounts. Using a single TOD replacement coupling will ensure the shaft is correctly aligned at all times, especially under high load. The result, reductions in many cases of around 50% in noise and vibration.


The TOD standalone unit that resists the propeller thrust compensating for up to 3 degrees in all directions.


Looking at the second vibration picture; you can see the usual method of connecting an engine with a propeller. The three fixed points, consisting of the propeller mount, the mechanical seal and the engine / gearbox, are individually or collectively capable of creating the two potential causes of noise and vibration. Firstly, any imperfect alignment of the three points can create vibration and noise. Secondly those vibrations and the associated noise are then transmitted directly through to the hull of the vessel and thence throughout the boat.
