Standard modifications:

Seal modification for biodegradable oil

To be able to sail in US territorial waters, you are obligated to use biodegradable oil in your thruster. Unfortunately it is not possible to just remove the existing oil and fill it up with a biodegradable type. All seals need to be suitable and completely clean to handle the oil. We can supply the standard seal kits to replace the existing standard ones. 

No manpower to perform this job yourselves? Our skilled service engineers can perform this job for you. On-site or in our workshop

Modification for under water propeller replacement 

Some of the HRP thrusters are equipped with deep sea seals. Most of these setups use the propeller to hold the seal in place. This is a nice setup, but unfortunately it is not possible to exchange the propeller under water in this case.

We can modify this seal setup. With this standard modifications you will be able to change your propeller under water in the case of any damages.
