MARINE PROPELLER INTERNATIONAL PATENT FOR PROPELLERS WITH COUPLINGS

The Sail Drive model J Prop propellers also exist in a version with tensioner (SDB). This version was developed due to the presence of stern-drive strength issues on the market.
The tensioner, internationally patented by Marine Propeller, is able to effectively cushion abnormal accelerations in the event of sudden maneuvers or small bumps, avoiding consequences for the transmission system.
The coupling version boasts two models:

  • SDP: fits small engines up to a maximum of 56 hp;
  • SDB: available for engines up to 120 hp.


Yanmar Marine International has also tested two J Prop propellers with “sd20” and “sd50” tensioners, the results obtained show that “SDB” and “SDP” are products with technical characteristics compatible with the Yanmar guarantee.
