 Good to know

The gearbox is not filled with oil before shipping to avoid contamination in the package. It is therefore urgently necessary to fill up with 10-15ccm gear oil before use.

Which oil should I use to fill my gearbox?
We recommend the use of our gear oil 

How much gear oil should I fill?
You should fill in 10-15cc gear oil. Under no circumstances should the gearbox be completely flooded with oil.

How often should I refill my gearbox with oil?
We recommend to check the oil level 3-4x per season and top up if necessary. 

My boat was completely flooded with water now what?
The old oil must be completely drained from the gear box. Then clean the gearbox with spirit (this binds water) and benzine. Thereafter, the gearbox can be refilled with oil and put into operation. 

My gear loses oil
Please check if actually only 10-15ccm oil was filled. Felt discs on the output shafts help to prevent contamination. To be on the safe side, you can use our rubber cuff set here # 1543-S 

Why do not you use Simmerrings?
Simmerrings would affect the smooth running of the transmission, so that this would no longer be suitable for electric motors.
